Subject: [mapserver-users] not unique image filenames problem
References: <000b01c1d64d$a34098b0$7e3c2fc3@HSGIS>
Message-ID: <000501c1d964$0f066980$0400a8c0@matt>

i set the mime type to img/(image type) and wrote the image right on to the
response

print "Content-type: image/$ctext\r\n\r\n";
open(FILE,$mapfile);
binmode(FILE);
@buffer = <FILE>;

foreach (@buffer){
  print $_;
}

close(FILE);

system("rm -f $mapfile");

i call this perl script right from the img src attribute.

also for my variable mapfile i used a exclusively locked file counter as
well as an application url token..  in case the filename was being generated
at the same exact second.

we did some serious stress testing and this is what worked best.  hope it
helps!

Programmatically everything with MapScript and everything is fine. But hey.

I've done everything of the europa example files which comes with its own
.map file.

I've just downloaded some shape files off the ESRI website. Specifically one
for San Francisco nad am inthe middle of trying to define a MAP file for it.
Seems like nothing I do will get it to work. I just end up getting an empty
graphic file. Not being particularly spacially minded, the .MAP file
definition on the mapserver website doesn't make too much sense to me at the
moment. is there a more concise referenceon the net covering both spatial
concepts as well as defining a MAP file?

any hints and tips regarding a map file would be much appreciated.

Cheers

Jeff:

How do I set up a getFeatureInfo on a mapserver layer? I looked
on the website but did not see the particular example for this.
But I did find your email link...

Also, is there a way to slave the "STYLE" request in a WMS getMap
request to go to one or another mapfile section? For example, I
have set up a current conditions weather data server with both
a WMS and WFS interface. Since it has many hourly parameters,
I'd like to expose many possibilities to label. One convenient
way to do this might be have one weather layer and have STYLEs
for each parameter that would set the label item or symbol 
differently, requiring different mapfile blocks.
Thus one could display temperature, dewpoint, wind direction, 
etc as "styles" of weather display.  Is this possible, or must
I treat these as distinct layers?

Thanks.

Doug.

Are you using the correct extents/units?

I had a smiliar problem...  I had also downloaded some shapfiles to test
with.  I couldn't determine the extents to use until I found 'shpinfo', a
util that gave me the numbers I needed.  My copy of shpfile errored out
after displaying the extents and I had to guess at the units to use.
Through some minor tral and error with different units I was able to get it
to work.

I found shpinfo in
ftp://gdal.velocet.ca/pub/outgoing/shapelib129_bin_win.zip  This is for
windows.

I hope this helps...

Ben,
In the imagepath you need to give the absolute path to this tmp dir. while
in the imageurl you will need to give the relative path to the tmp dir.
from your map file. Also your tmp dir. must have write permissions.
Also try checking the server's error log and mapserver's error log.

	Hi Dan,

	Yes, the version of GD is 1.8.4.
	I recompiled libgd 1.8.4 with -DHAVE_LIBTTF flag  as you  suggest. It works 
fine with  freetype-1.3.1.

	Thanks a lot,

You can defina a layer in your .map file like this:

LAYER
  NAME credits
  STATUS DEFAULT
  TRANSFORM FALSE
  TYPE ANNOTATION
  FEATURE
    POINTS 4 596 END    #Coordinates in pixels where you want your text
    TEXT 'Type your text here' 
  END
  CLASS
    LABEL
      TYPE TRUETYPE
               FONT Arial
      SIZE 7
      ANTIALIAS TRUE
      COLOR 0 0 0
      POSITION UR
    END

Is this specific to PHP-Mapscript? Or to Postgis (I use geometry POLYGON)?

Hi guys, kinda off topic but not really.  The terminology overlaps, but
I'll try it anyhow :)
I want to take an image of a map from mapserver and use HTML image maps
(not to be confused with "image of a map") as web links to other documents.
I know I could do the same sort of thing with Mapserver, but the target is
for offline usage.  If would be really nice to be able to do this kind of
thing in a PDF file but even just straight HTML would do.
Here's my (more direct) question.  Anyone got any ideas for how I could
take a shapefile or other vector data and use it as an HTML image map (aka
hotspots?) on a web page.  The input data would have some value in it that
points to a URL or other file.

Any ideas?  Boy that's convoluted to explain.

hi folks,

I apologize, I must have been out smokin' sump'n and missed the following
leap.

In PHP/Mapscript 3.4 there was a queryUsingPoint that returned a
queryObject. In fact, that still seems to be the case for Perl/Mapscript.
But PHP/Mapscript now seems to have acquired a queryByPoint(pointObj point,
int mode, double buffer) which returns an int.

So, what do I do with this? In Perl I still have the queryObject that can
give me the shapeIndex, etc. so I can have fun with the map. But I am now
stuck in a cul-de-php-sac.

As my daughter would say, "Like, wuzzup?"

tia,

Tyler,

The way I generated an HTML imagemap, was from mapscript...  you have
to loop thru all of the element of the labelCache and spit out all
of the bounding polygonal data for the labels and markers that you
place on the image.  I have an example of this someplace, but cant
locate it at the moment.  I will try to locate it for you later when I
get a chance...

Regards,

Chris Stuber (mapsurfer)

Dollars to donuts says you have a degenerate Shape file. All it takes is
a slight coordinate error, and the flood fill with get out of the
boundaries and fill in everything. Unfortunately, files which display
"just fine" in ArcView can occasionally have topology errors, because
ArcView will paper over some error cases.

Hi Tyler,

How it can be done:

1) Retreive shape
2) Get it's extents (geo-coords!)
3) Determine it's Center point
4) Translate Center point to Pixel-coordinates
5) Retreive shape-info from dbf-file

Looks something like this:

<MAP NAME="test">
<AREA SHAPE="CIRCLE" HREF="..." ALT="..." COORDS="167,253,10">
</MAP>

When you load the image, use like:
<IMG SRC="file" USEMAP=#test BORDER=0 WIDTH=400 HEIGHT=300
NAME=yourmapnam>

* HREF is your HTML or PDF you want to refer to
* ALT is 'mouse-hovering' information

Tip: use the overlib class from http://www.bosrup.com/web/overlib/

BTW, did some stuff on this earlier, and found out that it cannot be
used on the PHP/Rosa combination. Bypassed this to use a popup and then
use points of queried objects to use for the USEMAP (imagemap).

Does anyone know if Rosa can handle USEMAPS ?

Subject: [mapserver-users] HTML image maps and PDF

Hi guys, kinda off topic but not really.  The terminology overlaps, but
I'll try it anyhow :)
I want to take an image of a map from mapserver and use HTML image maps
(not to be confused with "image of a map") as web links to other
documents.
I know I could do the same sort of thing with Mapserver, but the target
is
for offline usage.  If would be really nice to be able to do this kind
of
thing in a PDF file but even just straight HTML would do.
Here's my (more direct) question.  Anyone got any ideas for how I could
take a shapefile or other vector data and use it as an HTML image map
(aka
hotspots?) on a web page.  The input data would have some value in it
that
points to a URL or other file.

Any ideas?  Boy that's convoluted to explain.

Aaron,

Yes you can do that. Define the layer in the map file with an empty
FEATURE END block. Then in PHP/Mapscript create a ShapeObj and add a
point with the location where you want the label to go and add the text
string to the ShapeObj. the get the Layer by name, and
$oLayer->addFeature($oshape); and draw the layer. I haven't actually
done this but I think it should work. Let us know the results. So
something like this:

$oPoint = ms_newLineObj();  # shape wants a line object as list of
points
$oPoint->setXY($myX, $myY);

$oShape = ms_newShapeObj(MS_SHAPE_POINT);
$oShape->set("text", "&#169; 2002 Name of Copyright Owner");
$oShape->add($oPoint);

$oLayer = $map->getLayerByName("release");
$oLayer->addFeature($oShape);

$image = $map->draw();
$oLayer->draw($image);

Or something very close to this anyway.

Subject: [mapserver-users] Best way of returning data at a point and doing something with it?
Message-ID: <TS3ZA6JESRVTVUDAEDCBVQ1TVUJHUVR.3ca9062b@rogers>

Hi,

First posting, so firstly I'd like to compliment the developers on the progress so far.  We've been trialling Mapserver for a month now, and have been able to make it do 
quite a lot thanks to the archives of this list and the docs so far.  Very impressed with the product.

This list is also pretty impressive.  I've been on the MapInfo-L list for about 8 years now, and thought it was pretty good, but the correspondance that flows though this 
list overshadows that list greatly.  Be a while before I'll be able to contribute much, but will probably develop some MapInfo apps to generate Map files etc. that I could 
share.  Look forward to the development on being able to read Mapinfo files also.

Anyway, we have reached a point in a project that we have to make some strategic decisions and we need some advice on the best way of proceeding from here.

We have a Image Web Server (IWS) app delivering aerial and satellite imagery to clients and MapServer delivering vector data to the IWS server on request.  We 
also have an ActiveX control on the client side to give a lot of functionality at the client end (possibly to be replaced by a java applet in the future when IWS goes 
java).  The application is for a captive audience so can be as specific as we want.  Once this one is over, we intend to port it to a linux server, and have a simpler 
client side app that isn't MS based, but for now it is on a M$oft site.

Our issue is to how best allow clients to query a location and change this data.

We have used the standard query tool to be able to extract the data from a shape file and display in a table with a map.  Very cute.  We also put some buttons on it to 
close the window and dummy submit button to a database that could contain code to write data back to the server.

But the data in the production system will be on a SQL server database, so it seems that we have a couple of options:
- making the data for the query layer to be a table, or preferably a view in the M$ SQL-server database (how hard is this?)
- make the query templates ASP pages that uses the ID retreived from MapServer to then retrieve the data from the database and display it in a table.

It seems that either way, the page can have a submit button that calls a subroutine to process any changes to the data on the client side and writes it back to the 
database.

The first option seems conceptually simpler and may be more powerful than we are giving it credit for, but the second option may be more flexable and allow us to 
eventually use a dll to do the data retreival from the database.  Like I said, am not sure of the implications of either, but would like any advice or pointers to docs on 
the subject.

Thanks in advance
Robert.

I tried to get the extents using arcExplore 3.1, but couldn't.  I don't
think it's meant to.

Regarding the shpinfo memory error...  Mine errored as well, but it
displayed the extent info before crashing.  I was able to continue my
testing with these numbers, however, I had to guess at the units.

If I get time I'll see if I can recompile shipinfo.c on my win2k box and get
around the error.

hi there

cheers for the quick reply. i've downloaded the shpinfo tools but it wont

do you happen to know how to get an extent of a shp file using ArcExplorer

Subject: [mapserver-users] Mapserver and mapscript APIS for color changing
Message-ID: <200204020607.BAA11466@www23.ureach.com>

Dear Mapserver Users !

I need to change the colors dynamically for certain polygins 
and/or for layers (depends on how the image is composed). The 
mapfile provides color definition, but I would like to change 
it based on some time-dependent process.

I plan to invoke the function (integrated into mapserver after 
processing the map file) or using mapscript.  

If anyone can suggest the APIs to use for 

-> layers color setting
-> individual polygon color setting (based on the attributes in 
*.dbf file)

I will very much appreciate it.

Thanks in advance,

Message-ID: <000301c1da16$9fa52320$55458990@tndn151qlhf5gi>

Hi All,

I use mapscript to dynamically create a point layer with the results of a
query to a MySQL table. Once a hash table is populated from a MySQL query
the following subroutine runs:


################################################################
sub make_unlabled_points {
    my ($layer_name) = @_;

    $layer = $map->getLayerByName($layer_name);

	    my $i = 1; # site counter
	    foreach my $s (@sample_sites) {
	        $point->{x} = $s->{lon};
	        $point->{y} = $s->{lat};
	        $point->draw($map, $layer, $img, undef, undef);
	        $i++;
	    }
}
###############################################################

Given a reference to an existing layer definition in the map file a nice
field of points is rendered.

The following is an example of one of the layers commonly used:

##############################################################
LAYER
	NAME sw_sites_no_lab
	TYPE point
	STATUS DEFAULT
	DATA locations

	CLASS
		SYMBOL 3
		SIZE 3
		NAME "sample sites"
		COLOR 254 0 0
	END
END
##############################################################

The reference to the DATA being in the locations shape file is irrelevant as
the layer definition simply provides symbology. And here is my problem...I
can now do more complex queries of my underlying data and would like to
render points in varying colours reflecting value ranges. How can I do this
with mapscript? The truly dumb and stupid way would be to define various
layers with different symbology but that limits me severely and gives no
real scope for user interaction like refining the colour ramp based on the
range of values in the returned data.

Regards

Steven Hayes

You may still have an older version running, Perl/Mapscript should also
return an integer on a query.? The resultCacheObj's now stay in the
layerObj.

I don't know if you have looked at or used any mapscript yet but
option 2 would be easily done using mapscript/Perl or PHP. Your second
option seems to point more towards a PostGIS/SDE/SDO setup which could
also incorporate mapscript but not need to.

Hi all,

i like to use a map at my website to map the registered users.
I use php and mysql. I have a cgi-bin folder.

You can see my first implementation at
http://www.jan-mantkowski.de/modules.php?op=modload&name=map&file=index.
The map part is not working, because there is no mapserver right now.

Unfortunately the mapserver seem nbot to be available as a "ready to
install" file like the windows binaries. 

Where can i get a compiled version?

I do not have linux, unix whatever nor do i know how to use.

Is there a version available that i can put into the cgi-bin folder and that
will do the work?

How can i get out what operating szstem is in use at my website?

Thanks,

Jan

$paramgk[5] = "x_0=3500000.";
$paramgk[6] = "y_0=0.";
$paramgk[7] = "units=m";
$projgk     = pj_init($paramgk);

$ret = pj_transform($projll, $projgk, $lon, $lat);
$x = $ret["u"];
$y = $ret["v"];

echo "Input:<br>Longitude: $lon <br>Latitude: $lat<br><br>";
echo "Output:<br>x: $x <br>y: $y<br>";
?>

I get the result: longitude 9 deg east  -> x = 3500000. (ok)
                  latitude 54 deg north -> y = 5985297.54 (that is Bessel ->
Bessel ellipsoid)
but it should be: latitude 54 deg north -> y = 5985234.24 (WGS84 -> Bessel
ellipsoid)

These results are the same when transforming 9 deg E, 54 deg N with
cs2cs +proj=latlong +ellps=WGS84 +to +proj=tmerc +ellps=bessel +k=1.
+lat_0=0. +lon_0=9. +x_0=3500000. +y_0=0. -v 
It seems that the transformation uses the same ellipsoid for both systems
(Bessel in this case).

Are there any hints?

Andreas

Do you mean making a layer queryable via GetFeatureInfo WMS requests? 
Simply setting a query template in your layer definition in the mapfile
makes it queryable in the WMS Capabilities, and then you can use it in a
GetFeatureInfo request.

GetFeatureInfo supports up to three INFO_FORMATs in the latest version
of MapServer depending on your configuration:

- INFO_FORMAT=text/plain - List feature ids and attibute names value in
plain text format

- INFO_FORMAT=application/vnd.ogc.gml - returns selected features in
GML  format.  You also have to set "DUMP TRUE" in your layer to enable
this.

- INFO_FORMAT=text/html - Uses the MapServer query template to produce
query results in HTML format.  Works exactly like the traditional
mapserv CGI query templates.

SLD and STYLEs are not supported by the current version.  If I properly
understood what you're trying to do, then it would seem that defining
separate layers would be your best option for now.

Andreas,

The problem is that you haven't specified the datums and PROJ.4 doesn't
automatically convert between ellipsoids.  If you want do the above
translation and assuming no datum shift is needed (likely a bad assumption)
you would just need to specify "0" datum shift parameters.  Use +datum=WGS84
for WGS84, and "+ellps=bessel +towgs84=0,0,0" for the bessel indicating that
no datum shift is required to shift to wgs84.

Hopefully I will incorporate some improved warnings into PROJ.4 in the future
as this is a frequently encountered problem.

Best regards,

Daniel,

You had a really funny quote in your email the other day... something to the
tune of...

"when we discover what we were doing wrong all this time, its a wonder it
worked at all...."

I quite accidentally had been using drawMap() for rendering my map, until I
discovered that was not a part of PHP/Mapscript 3.5 anymore. So, how the
heck does it still work? Did you folks leave it in there for
backward-compatibility?

:-)

drawMap() is not there at all in PHP/Mapscript 3.5 ... you should get an
error about this in your HTML source (do a "View Source" in your

Message-ID: <NGBBKAMCKLCAGHNOCHILAEAACDAA.jan.mantkowski@gmx.de>

Hi,

is there a chance to have a version of Mapserver that will run at real cheap
webspace.
With cheap i mean everything less than 90 US$/year.

In general it is not possible to compile or to place files in the php
extension folder or to change the php.ini file.

Is there a version available that can be placed in the cgi-bin folder and
will just run?
Without any compiling etc.


Thanks,

Jan

Subject: [mapserver-users] Help with compiling on Windows?
Message-ID: <LAW2-F108JBKGMuiS1x00019880@hotmail.com>

Hello,
I'm new to MapServer and at this point I'm still evaluating it.  So far I'm 
very impressed.  However, one of the key items I need to evaluate is its WMS 
Client capabilities.  I'm currently using the binaries on Windows 2000 that 
I downloaded from the homepage.  Per the instructions, I executed "mapserv 
-v" to check out what capabilites it was compiled with.  WMS Server is in 
there, but not WMS Client.  So I thought, no big deal, I'll just recompile 
it and turn on WMS Client.  I didn't know what I was getting myself into!!! 
I'm not a C programmer.  I've followed instructions, searched mailing list 
archives and 3 days later I don't feel like I'm getting any closer.  It 
seems that compiling MapServer itself is straight forward as there is 
documentation and a VC++ makefile.  However it is all the supporting 
libraries that I'm having problems with... and it looks like the regex 
library wasn't even meant to compile on windows.  I think it would've been 
very helpful if, whoever compiled those binares for windows, also made 
available the source that was compiled.. even without documenation.  Then I 
could learn by looking at the changes that were made in order to compile on 
Windows.
I need all the help I can get but I don't expect anyone to spend tremendous 
amounts of time with me.  So maybe, at a minimum I could get someone who has 
successfully compiled version 3.5 on Windows to jot down a few clues. Some 
sample questions I have are..
My understanding is that I need to get ZLib, FreeType and LibPNG copmiled 
first.  Then those three will be used to in the GD compiling process.  Then 
all of the above will be used in the MapServer compiling process.... am I on 
the right track?
Regardless, I can't get anything other than PROJ4 to compile.  For those 
libraries that don't have a Makefile.vc that I can't use VC++ on, what do I 
use to compile?  I downloaded a gcc compiler that has the "make" command, 
but that doesn't seem to work on any of the makefiles and gcc compiles .c 
files into .exe's when I really need .lib's...
I think I could get MapServer compiled if I could just get all these 
supporting libraries how they need to be.

I don't expect anyone to answer ALL my question, but any little bit of 
information would be GREATLY appreciated!!

It works... I was able to determine the extents and unit with ArcExplore 3.1

I'm still very new with Shapefiles and GIS in general.  I was hoping shpinfo
or shpdump would present whatever information contained in a file in an easy
to read/understand tabular layout.

Thanks for the info.

i am trying to change the image size that gets drawn with mapscript using
the $image=$map->draw() function.

i change the dimensions before drawing each time:
$map->width=400;
$map->height=400;

and i have changed the dimensions of the image in the HTML code.
this works, but the problem is that it doesnt REALLY change the output size
of the actual GIF image i am using.  all that happens is that the 600x600
image gets scaled down to whatever size i told it to.  this is unacceptable
because in scaling down, many border lines are lost and the image is
confusing.  any ideas?

You should use:

  $map->set("width", 400);
  $map->set("height", 400);

If you only need the binarries, the mapserver site provides windows binaries

Sometimes I do.  I'll think that I just read a message, then get it the
following morning again :)
I thought it was only when someone would reply to all - both me and
mapserver gets a copy. (like my response to you :).   Are you getting
something more than that?
I noticed that you email said it was sent 8:28am - I received it at ~10:45
- strange.

Is anyone else receiving multiple copies of posts?  I seem to be getting
second and third copies of some posts, delayed by a few days.

Hello Mapserver-users,

I observed that this is happenning for last couple of weeks.
Nothing is changed on this machine which might have caused 
this problem.  One strange thing is that not all messages 
are duplicated. This is an unknown problem, so might take 
a while to fix it.  If anyone knows more about majordomo 
administration and can share useful information, then please 
send me a mail (vrraju at gis.umn.edu).

Thanks
Raju

Yes. But I don't consider it a problem as long as I receive all the
postings.

Using the straight 'mapserv' cgi may be your only option. Just make sure
to compile it on the same os (with hopefully the correct options) as the
web server before uploading it.
Making sure the temporary files are cleared out on a regular basis so as
to not exceed your space limits is a different matter.

Thanks Raju, 

Because I hadn't seen any postings about the problem, I assumed that it was either a chronic case of deja vu or a mail server problem on my end.

Thanks for clarifying the problem.

Frank,

There are several MapServer binaries for Win32 available in the
MapServer site.  Some of them have WMS client support turned on and some
don't.  If you really want to compile them on your own using VC/C++ 6.0,
I've packaged my source tree awhile back and made it available for
download at http://arbutus.gis.umn.edu/projects/ms35.zip.

It's about 95 Mb so might take forever to download if you're using a 56K
modem.

Good luck!
Perry N.

Subject: [mapserver-users] Help with compiling on Windows?

Hello,
I'm new to MapServer and at this point I'm still evaluating it.  So far
I'm 
very impressed.  However, one of the key items I need to evaluate is its
WMS 
Client capabilities.  I'm currently using the binaries on Windows 2000
that 
I downloaded from the homepage.  Per the instructions, I executed
"mapserv 
-v" to check out what capabilites it was compiled with.  WMS Server is
in 
there, but not WMS Client.  So I thought, no big deal, I'll just
recompile 
it and turn on WMS Client.  I didn't know what I was getting myself
into!!! 
I'm not a C programmer.  I've followed instructions, searched mailing
list 
archives and 3 days later I don't feel like I'm getting any closer.  It 
seems that compiling MapServer itself is straight forward as there is 
documentation and a VC++ makefile.  However it is all the supporting 
libraries that I'm having problems with... and it looks like the regex 
library wasn't even meant to compile on windows.  I think it would've
been 
very helpful if, whoever compiled those binares for windows, also made 
available the source that was compiled.. even without documenation.
Then I 
could learn by looking at the changes that were made in order to compile
on 
Windows.
I need all the help I can get but I don't expect anyone to spend
tremendous 
amounts of time with me.  So maybe, at a minimum I could get someone who
has 
successfully compiled version 3.5 on Windows to jot down a few clues.
Some 
sample questions I have are..
My understanding is that I need to get ZLib, FreeType and LibPNG
copmiled 
first.  Then those three will be used to in the GD compiling process.
Then 
all of the above will be used in the MapServer compiling process.... am
I on 
the right track?
Regardless, I can't get anything other than PROJ4 to compile.  For those

libraries that don't have a Makefile.vc that I can't use VC++ on, what
do I 
use to compile?  I downloaded a gcc compiler that has the "make"
command, 
but that doesn't seem to work on any of the makefiles and gcc compiles
.c 
files into .exe's when I really need .lib's...
I think I could get MapServer compiled if I could just get all these 
supporting libraries how they need to be.

I don't expect anyone to answer ALL my question, but any little bit of 
information would be GREATLY appreciated!!

Scott,

Think you need to use (PHP) something like this:

$Map = ms_newMapObj("yadayada.map");
// Resize to specific size
$Map->set("width",400);
$Map->set("height",400);

i am trying to change the image size that gets drawn with mapscript
using
the $image=$map->draw() function.

i change the dimensions before drawing each time:
$map->width=400;
$map->height=400;

and i have changed the dimensions of the image in the HTML code.
this works, but the problem is that it doesnt REALLY change the output
size
of the actual GIF image i am using.  all that happens is that the
600x600
image gets scaled down to whatever size i told it to.  this is
unacceptable
because in scaling down, many border lines are lost and the image is
confusing.  any ideas?

$map->{width} = 400;
$map->{height} = 400;
Should fix it.

Yes I am also getting two emails many times, also I have another problem,
generally if I post my mesg. at 10:00 in the morning it shows up in the
list after 2-3 hrs. But it reaches Steve Lime and other people who are
managing the list immediately.

Frank,

In MapX they call it FeatureID and I guess it is the feature numbers (order)
in table file.
But anyway, it looks like it is going to be simpler and more reliable to use
an ID field
which is created by Mapinfo application.

Thanks

Ari,

I am not sure what you mean by feature id.  The features in a tab file
are numbered (at least by the OGR API).  Is that the feature id you
want?  Are you wanting it from MapScript?

Hmmm... Good point.
Attached is an update to the dump.pl in the mapscript/perl/examples
directory that prints the bounding rectangle at the end of the printout.
Note: If your running it on a big shapefile and are interested in more
than just the final extent make sure to send the output to a file.

Well, there is no priority here ...
Mail processing is done sequentially, and this sequence is established
in the order of subscription (i.e. first come first basis). Steve Lime
gets it first becasue he is one of the first subscribers to the list.

I explained the reason for the delay before, here goes it again.
We have more than 500 subscribes now and some of them are defunct 
permenantly and some are temporarily. For these defunct users, 
mailing system tries several times before givingup and sending 100's 
of error messages to the people who are managing this list - and hence 
the delay.

Well, it takes few weeks to establish these defunct users and remove 
them from the list. Any ideas on how to make things fast are welcome.

Thanks

NO this is a REAL problem!
and it has been happening for over a month now!!

I have checked the full headers like the one below, and in every case it
is coming through taiwan.com. 

Could you see if we have a user subscribed from taiwan.com and
unsubscribe them until they get there mail problems straightened out. or
maybe you can make more sense out of the headers.

It is a most annoying problem.

Thanks for any help in fixing this problem.

I think I have an idea about this. There is a serious bug in the build
environment - when you build mapscript it does NOT link with the just
built libmap.a!!!! It links with the installed version of libmap.a if it
exists! The Makefile(s) for mapscript need to explicitly load
../..libmap.a so insure that the correct one is loaded.

Puneet, see if you have a /usr/lib/libmap.a or /usr/local/lib/libmap.a
and delete it then make clean; make and you will probably get the error.

Could somebody chnage the Makefile(s). I will add this to bugzilla.

Steve,

You could well be right, except in my case it was simply a case of my right
brain not knowing what my left finger was doing. I had written a function
and forgotten all about it, and was inadvertently calling it.

Essentially, I got lost in my own code, and hence it was all my fault.

That said, you may well be right about the bug you note below. I will check
my server and see what all I've got.

Thanks,

Subject: [mapserver-users] [Solved] PHP-MapScript, Postgis & fills of
 polygons /w inner rings
In-Reply-To: <sca87fe8.095@co5.dnr.state.mn.us>

Yes, it works, even for 'lakes on islands in lakes'.

The problem was that I did not realize that EOO files contain the polygons 
in the PAL section twice - once as inner rings inside other polygons and 
once as free outer rings.

The holes were there, but covered with the second instance of the same
polygons, now as free outer rings and thus of the same color.

I changed my e00->postgis script so free outer rings are ignored unless 
they are on top level and, surprise, I got the topology out of the 
e00-files.

My script (Perl) is available for anyone interested at 
http://untamo.ngb.se/download/e002pgis.pl

It's nothing fancy - it will just extract polygons, nothing else, and (for
now) only handles single precision data. But it will rebuild topology
directly as a sequence of INSERT statements for Postgis.

Thanks to all who responded. It's much easier to debug when you know
something works for others. Then you know your own scripts are to blame.

Hello Mapserver-users,

I have unsubscribed several users - based on compilation of bounced messages
(due to several reasons - mostly problems at users end). This should help 
speeding up things (i.e., gap between users posting and reception). Coming
to duplicates, still I couldn't assertain the problem, however, I unsubscribed
the user pointed by Stephen Woodbridge. I will send a seperate mail to each
of these users, but in case any genuine user stopped getting messages - please
send me a mail at vrraju at gis.umn.edu. I will resubscribe them.

Thanks for bringing this to notice and bearing with me.

Best wishes,
Raju

Message-ID: <200204030516.AAA31006@www20.ureach.com>

Dear mapserver users!

Thanks in advance for the help!

If there are a attributes defined for each shape in *.dbf file, 
let's say STATE and LEVEL. State is a string and level is an 
integer.  I need to use it from the map file to set the color. 
Is it sufficient to use the expression , for ezample:

CLASS
  EXPRESSION ([STATE] = &#8220;Alaska&#8221; and [LEVEL] > 3 and [LEVEL] < 
6 )
  COLOR 255 0 0
END
CLASS
  EXPRESSION ([STATE] = &#8220;Virginia&#8221; and [LEVEL]  > 6 and [LEVEL] 
< 9 )
  COLOR 0 255 0 
END

Well, I tried , it does not do anything. But even if it does, 
does it set the color for each shape in the layer? (Not sure)

Thanks a lot

The states must be quoted in the expression, e.g.:

Thanks Frank,
it is good to know how to specify all necessary parameters for the datum
shift to get the proper results. I am now able to add the Potsdam datum
parameters to the transformation.

Andreas,

The problem is that you haven't specified the datums and PROJ.4 doesn't
automatically convert between ellipsoids.  If you want do the above
translation and assuming no datum shift is needed (likely a bad assumption)
you would just need to specify "0" datum shift parameters.  Use +datum=WGS84
for WGS84, and "+ellps=bessel +towgs84=0,0,0" for the bessel indicating that
no datum shift is required to shift to wgs84.

Hopefully I will incorporate some improved warnings into PROJ.4 in the
future
as this is a frequently encountered problem.

Best regards,

Thanks, now it works.  The problem appears to have been the
permissions on the tmp dir.  I gave them 775, but they need 777 (the
cgi doesn't run under my uid).  Stupid mistake on my part...I've dealt
with that problem a 100 times on my own CGI's.  :)

It also worked to convert all the GIFs to PNGs and replace all
occurrences of .gif with .png in demo.map.  Now the symbols all work.

Thanks,
Ben

Subject: [mapserver-users] Problem with DD
Message-ID: <047701c1db0f$0aca3160$0601a8c0@comai.loc>

I have developed a MapServer application where the North Italy Map is
displayed.

My problem is the following:

in the map file I have written the following code:

NAME DEMO
STATUS ON
SIZE 600 600
EXTENT 6.174567 42.975424 14.815678 47.143435

UNITS DD
SHAPEPATH "data"
IMAGECOLOR 255 255 255
SYMBOLSET /Inetpub/wwwroot/Nord/symbols/symbol.sym
FONTSET /WINNT/Fonts/fonts.list
....
....
....

but the Italy Map doesn't appear entirely (only a piece) and if I try to
increase the DD interval MapServer show me the same piece of map.

Why?

Thanks in advance.

Message-ID: <001101c1db35$43502500$967ba8c0@xp>

Regarding my first question I did get some useful answers, however ...

Is there a low budget Viewer + database-editing option available?
In general only ESRI shapefiles are used, so that should keep a lot of
options open.

The reason why I ask is because local resellers are referring to huge
program's, often based on a webserver or the viewer uses a non-standard
file-format.

So if I go out in the field (uhu uhum) with a laptop/PDA and want to
edit data of an object, what would be a simple program to use?

Setting up mapserver+apache+PHP could do this, but I was looking for
another (quicker) solution.

Any tip is more then welcome!

Erwin

Hi All,

I know this is totally off topic, but are there some good GIS-viewers to
view maps also used by Mapviewer on a laptop without a webserver ?

Functionality should be no more like:

* Zoom
* Pan
* Identify/Query
* Search

All data are ESRI shape-files and some GEOTIFF's.

Did some searches on the internet, but did not come up with many
results.

Now I only use ArcExplorer from ESRI, but are there other low-price
solutions available?

Thanks in advance,

Erwin

I'm sorry, I haven't been following this thread but why not get
ArcExplorer2 which is a free download from the ESRI site?

Granted it is view only app. As soon as you want to edit files the
problem become a little more complex. :)

Hi Steve,

ArcExplorer2 or 3 are both perfect,... but only for viewing.

Agree, once it comes to editing it becomes quit a small selection ;-)

MapServer Error in msDrawShape(): Only polygon shapes can be drawn using a
POLYGON layer definition


I get the above error _only_ when I try to zoom around the map. That is, I
am able to draw the map fine while identifying (by clicking) or by directly
zooming to a known feature. I have a map file with 5 layers in it... 4 are
polygons and 1 is lines. As I said, if I search for a feature using an
attribute, or if I click on an existing map and identify and zoom to the
selected feature, it draws just fine.

This is driving me nuts.

Many tia,

Hi,

I am developping a Web Mapping Service. And I have to cascade from a wms
client to a wms server for a feature_info request. If I query directly the
server, I get this:

GetFeatureInfo results: 
	Layer 'Quaternary' 
	Feature 0: 
		AREA = '8.09571119107E-001' 
		PERIMETER = '8.97066357990E+001' 
		GEO2005P_ = '2'

		GEO_PAT = '0' 
		GEO_PAT_CO = '0' 
		GEO_MISC = '' 
		GEO_LINK = '0'

		GEO_PAT = '0' 
		GEO_PAT_CO = '0' 
		GEO_MISC = '' 
		GEO_LINK = '0' 
		CODE = 'R' 

which is what I want to get. And from the client I receive this:
	:

which is nothing in fact. I am searching for a way to get the same thing
from the client as from the server.
Someone has any idea ? Or any explanation on the reasons why it wouldn't
cascade?

Erwin, do you need to do the database editing within the same application
as the one that will do the viewing of the map data?  If not, then you
could simply you Excel or Access to do the database editing and use
something like ArcExplorer or OpenEV to look at your shape files.

I'm sorry, I haven't been following this thread but why not get

Granted it is view only app. As soon as you want to edit files the

Hi Tyler,

It is important that it is a combined view/edit program because the user
needs to select the object to be edited and then easily fill in a new
value like house-number or alike.

When using CDBFW, Access, Excel or alike, he then also needs to find the
id-number and only then he can edit the value. Too much hassle for use
on a laptop ;-(

Thanks,

Erwin

Erwin, do you need to do the database editing within the same
application
as the one that will do the viewing of the map data?  If not, then you
could simply you Excel or Access to do the database editing and use
something like ArcExplorer or OpenEV to look at your shape files.

what is wrong with this PHP code?  i am trying to create a layer of points

Subject: [mapserver-users] inconsistent PHP/Mapscript non-object error 
Message-ID: <3CAB6A16.498A5CBB@geoarctic.com>

Hi All,

My setup:
IIS 5.0
PHP 4.06 as cgi
PHP/Mapscript

I've come across the wierdest of problems with a php script on two
different IIS 5.0 machines.  In my script, with no parameters passed, it
displays a simple map.  I then flag labels on, zoom to different
extents, and the map still displays (on both machines).  The problem
lies with one machine, where I try to turn specific layers on with a php
isset/switch combination, the script bails with an error with:

Call to a member function on a non-object in
C:\MYWEB\newsite\gedcomap\mapscript\postmap.php on line 164

My line 164 is:

$img->saveImage('',MS_GIF, 1, 1, 75);

Now, it is obvious in the error that the $img object no longer exists,
but for the life of me can't explain why it works on one machine, and
not the other.

Any thoughts, ideas?

Message-ID: <scab15d6.072@co5.dnr.state.mn.us>

I don't believe this can be classified as a build bug. One could call it
a feature of ld. If you
"install" libmap.a in the system libraries then of course you need to
install the new one
before building mapscript. The same goes for GD, Freetype, libtiff
etc...

Changing the Makefile won't help. Libs in the system directories always
override local copies.

I think I have an idea about this. There is a serious bug in the build
environment - when you build mapscript it does NOT link with the just
built libmap.a!!!! It links with the installed version of libmap.a if
it
exists! The Makefile(s) for mapscript need to explicitly load
../..libmap.a so insure that the correct one is loaded.

Puneet, see if you have a /usr/lib/libmap.a or /usr/local/lib/libmap.a
and delete it then make clean; make and you will probably get the
error.

Could somebody chnage the Makefile(s). I will add this to bugzilla.

further info on this...

I found a layer (the layer) that was causing the problem. When I take that
layer out of the map file, the map draws fine.

I changed the TYPE definition from polygon to line, and still got the above
error. Changed it to point and it drew fine.

Arcview shows it up as a polygon layer filled with all "area > 0" polygons.

The weirdest thing is that the above error does not occur when I draw the
map by clicking on it, such as when identifying a feature.

Any ideas anyone?

Hi Scott,

There is nothing wrong with the PHP code, except it does not create a
layer, but it creates a new shapefile ;-)

So you want to create a layer, dynamicly, or .....

Example of creating a layer from a shapefile:

0) Create map-object
1) Get object/points from existing-shapefile or from database
2) Put it in new-shapefile (as you did in your php-script)
3) Create dbf-file with name of new-shapefile
4) Clear new-shapefile (as you did)
5) Add new-layer to map-object (default of this layer is set to OFF)
6) Show new-layer (turn it ON)
7) Draw the map (now includes newly created shapefile ;-) )

Explanation:

*** In 0) you use like: $Map = ms_newMapObj("blabla.map");

*** In 1) you determine input. This could be the 3 points you have in
your example, but also could be a shape or lat/lon from a database (eg.
dbf/MySQL)

*** Option 2) and 3) and 4) you have in your mapscript. This creates a
shapefile + corresponding dbf-file.

*** Option 5) and 6) is best done using a dummy-layer which is set to
OFF in your map-file. You turn it on AND attach the new shapefile-data
from by using:
	$Dummylayer = ms_newLayerObj($Map);  // a new layerobject
	$Dummylayer = $Map->getLayerByName("MapLayer");  
	$Dummylayer->set("status", 1);	       // Turn it on 
	$Dummylayer->set("data", $shpFname);       // Add your created
data

	While your map-layer looks something like:

	LAYER
	  NAME "MapLayer"
	  TYPE POINT
	  STATUS OFF
	  CLASS
	    SYMBOL 'circle'
	    COLOR 0 0 0
	    SIZE 3
	  END
	END

*** Option 7) is something like:

$ImgMap = $Map->draw();

This should do the trick.

But mapscript gets built as part of make with the wrong library. So what
you are saying is ...

 1) make to build libmap.a
 2) make install to install the new lib
 3) make clean to remove the bad mapscript that was built the first time
 4) make again to build everything with the correct libmap.a

OR

change the Makefile to explicitly load the libmap.a you just built and
expect to be loaded as part of the build process.

AND

if you don't know all about this in the first place you are basically
screwed!

I think the general expectation is that when I build mapserver and
mapscript that it gets built with the current libraries not some left
over thing that is just out there from the last time you installed
software some 3, 6, 9 , 12, 18 months ago.

I agree this is a good feature of ld, but I respectfully disagree that
our Makefile(s) should pick up the old version when it is a simple
change to force it to pick up the correct one.

Libs in the system directory are only loaded based on the -L path and
-lmap directives, if instead ../../libmap.a were explicitly loaded like
a .o file this problem would go away. Here is the change I made to my
Makefile:

php_mapscript.so: $(PHPMS_OBJS) ../../libmap.a
        $(LD) -o $@ $(PHPMS_OBJS) $(MS_LIBS)

which I think you will find solves this problem.

My point is that if you're going to install libmap.a in a system
directory and don't replace it
when appropriate then you're bound to run into problems at some point.
There is no
"make install" for libmap.a as part of the main makefile for just that
reason. Unless there's a
good reason to install libmap.a (you're building your own C/C++ code
using it) then there's
no reason to install it.

Dan's the keeper of the PHP code so he'll have to make those
changes...

Something kinda weird... maybe someone knows what's going on...

In my perl mapscript file, when I call a raster layer's draw method with a
die clause attached to the end of it, it'll die every time.  When i remove
the die, it lives and my raster is drawn.

I'm just curious if anyone knows why this is.  Thanks!

I get an array with the correct number of elements in it... but the elements

Greetings,
    I am attempting to combine multiple shapefiles (data from different

multiple layers which must be handled seperately in the mapfile?  Is
there a standard method which will preserve the ability to querry
the data?  The mapfile syntax does not seem to allow multiple data tags
for a given display layer.  This leads me to wonder if there are tools
which can merge shapefiles into a larger superset.  Is anyone aware of
such a tool?

Joe,

I believe you want to use a tile index. See the utlities for a program
called tile4ms. Say you have a roads layer for every country, then you
can make a tileindex for all the roads file and then create one layer in
the mapfile and reference TILEINDEX instead of DATA. You can create a
separate tileindex for each kind of data set, like rivers, cities,
landuse polygons, etc.

Hi Steve,

I'm referring to our mails in march this year.

You write that PHP/maspcript crashes too. How do other people handle 
this problem or is mapscript not used at all?

Of course I can call the cgi-program from a java-servlet, but thats not 
so comfortable and not the intention of mapscript.

THanks a lot for your help.

Harald,

I believe Frank or Dan responded to my message about mapserver thread
safety and corrected my mis-informed statements. Please concided my

A lot of people use mapscript built as CGI without a problem.

There is a mechanism in the MapServer that already supports this -
tiling. Basically you create an index shapefile that contains boundaries
for the various shapefiles in the layers (in you case counties). The
index shapefile then references the individual shapefiles as an
attribute. The default attribute is 'location' but you can call it what
ever you'd like to (then use TILEITEM parameter) and can even use a
single tile index for multiple layers (e.g. you have roads and lakes
tiled by county). Support for query of tiled data is supported in
version 3.5+. See the documentation (and perhaps the wiki) for more
details.

    I am attempting to combine multiple shapefiles (data from different
counties) into single layers.  How can I do this without declaring
multiple layers which must be handled seperately in the mapfile?  Is
there a standard method which will preserve the ability to querry
the data?  The mapfile syntax does not seem to allow multiple data tags
for a given display layer.  This leads me to wonder if there are tools
which can merge shapefiles into a larger superset.  Is anyone aware of
such a tool?

How I can protect my files under "data" directory ?

My MapServer is running on Linux and I try to change the "chmod", without success.

Message-ID: <18E0CC75605BD411907800508B8BB8D049E528@odin.enator.dk>

Hi,
I've succesfully run the Gmap and Itasca demo and managed to replace the old
shp-files with my own, but now I want to retrieve data from a database.

On the main page of MapServer it is said: "If the data has a spatial
component and you can get to it via your favorite scripting enviroment then
you can map it."

But I can't find any documentation on data from a database. How can I pass
the data on to MapServer?

I want to use Perl or PHP on Apache HP Unix. I have my spatial data in an
Oracle 8.1.6 database (not Oracle Spatial).

What  to do? 
Any suggestions will be highly appreciated.

Regards
Bjarni Thor Pjetursson

Puneet...

I had some similarly perplexing problems with a poly shapefile about 6
months ago. In my case, the polygon just wouldn't render in my MapServer
app, and I couldn't query the polygon by "clicking" on it, but I could get
it to show up based on a logical query (i.e. turn polygonid=32 red).

On the other had, everything rendered fine in ArcView. For what it's worth,
these were data sets that I had converted to shapefiles from DGN. I think
what I finally ended up doing was converting the shapefiles to ArcInfo
coverages, cleaning them, then converting them back to shapefiles. For some
reason, this seemed to fix the problem, although I have no idea what the
underlying cause was.

further info on this...

I found a layer (the layer) that was causing the problem. When I take that
layer out of the map file, the map draws fine.

I changed the TYPE definition from polygon to line, and still got the above
error. Changed it to point and it drew fine.

Arcview shows it up as a polygon layer filled with all "area > 0" polygons.

The weirdest thing is that the above error does not occur when I draw the
map by clicking on it, such as when identifying a feature.

Any ideas anyone?

Hi,
I ve installed mapserver 3.5 on a suse linux 7.2 with proj support.
When I run ./mapserv -v i have :
Mapserver version 3.5 OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP SUPPORT=PROJ
SUPPORTS=TTF SUPPORT=WMS_SERVER INPUT=TIFF INPUT=EPPL7 INPUT=JPEG
INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE.
I understand that proj support is supported.
But when I put a projection clause in may mapfile I got the following
message :

Warning: MapServer Error in loadProjection(): Projection support is not
available

If someone can explain this to me or tell where I can find something
about using the proj clause even with mapscript....

Thanks

Stef

Do you have the NAME value filled in your map file (like below)?

  LAYER
    NAME "OP0"
    DATA o20_scale.tif
    MINSCALE 24600
    STATUS DEFAULT
    OFFSITE 0
    TYPE RASTER
  END

  LAYER 
    NAME "OP1" 
    MAXSCALE 24600
    MINSCALE 9218
    STATUS DEFAULT
    TILEINDEX "tile_test\s10images\o_10scale.shp"
    TILEITEM "Location"
    TYPE RASTER
    OFFSITE 0
  END

I ran the following code on a map file and it worked fine...

<?
$map = ms_newMapObj("test.map");
$a = $map->getAllLayerNames();

foreach ($a as $v) {
  echo "$v<BR>";
}
?>

btw... I'm running 3.5 mapscript, php 4.06, win2K w/ IIS.

I get an array with the correct number of elements in it... but the elements

I guess I will have to do something like this as well. 

But, here's the funny thing. Exactly the same layer (same physical layer,
same definition in the map file) works just fine in MS3.4, but croaks in
MS3.5.

Additionally, as I noted, as long as I don't use any of zoom methods, it
draws ok as a polygon. As soon as I use a zoom method, it complains that it
is not a polygon.

Tested it in Arcview for unclean polys, or polys with area not greater 0...
nothing out of the ordinary at all.

I think the line:

  print "$layers[i]<br />";

should be 

  print "$layers[$i]<br />";

...I hate it when that happen ;)

I have a related question, in php/mapscript I show the user a html list
from which he/she can select layers to add to the current view, I am
writing some code but it doesn't work can somebody provide me with the
algorithm if not the code like the one given below:
if ( isset($HTTP_POST_VARS["layer"]) ) {
   echo $HTTP_POST_VARS["layer"];
   $layer = $map->getLayerByName($HTTP_POST_VARS["layer"]);
   $image = $map->prepareImage();
   $layer->draw($image);
   $image_url = $image->saveWebImage(MS_PNG,1,1,0);
}   // end of if loop
The above code doesn't work it creates a blank image, moreover if one
selects multiple layers to display then only the last one selected is
chosen.

found it... there was a null shape. I guess, ms3.4 was forgiving where ms3.5
is not.

thanks everyone.

btw, if someone can explain to me what is a null shape I will find my
curiosity satisfied. is it when there is no geog feature but a dbf row
exists? it certainly is not a feature with area = 0. I mean, isn't the
absence of a feature simply no feature?

Hi,

I have a few more questions re: tiling.

The tile4ms utility doesn't support the specification of the TILEITEM 
parameter (i.e., it is always LOCATION), nor does it allow the 
merging of a tile index into an existing tileindex file.

I presume that the only way to create a multicolumn tile index (thus 
allowing the use of multiple TILEITEMs from within the .map file) is 
to write a separate program (e.g., using Perl's XBase module) to 
aggregate multiple tileindex files into a single .dbf file. Is this 
the correct way?

What are the advantages to creating such a multicolumn tileindex, vs 
using separate tileindex file for each logical dataset? Is it more 
efficient?

Also, is it better to create a spatial index from the individual 
shapefiles in a tileindex, or is it better (or even possible) to 
create a spatial index from the composite tileindex?

Thanks

legend depends on the existence of a CLASS NAME. Take away the NAME and the
legend won't be created for that layer.

Unless you declare a NAME withing the CLASS it will not print in the

Hi Pushkar,

Just to check the obvious,....

1) Does it echo the layername?
2) Should you not use 'explode' for $layer when multiple are selected?
3) Is the layername an existing one and not too long?
4) Is the layer STATUS set to: DEFAULT or ON ?
5) Is the layer set in your url like: 
   http://localhost/.../name.php?zoom=1&layer="layer1 layer2 layer3"
6) You sure POST is correct? Did you check GET ?

Option 2) should use a string like "layer1 layer2 layer3" (see option 5)
and then you explode it using the space so you then use $layer[0] for
your first layer of the 'original-string-array'

For exploding use something like:

$LayerArray = explode(" ", $HTTP_GET_VARS["layer"]);

Then from the example above you get:

$LayerArray[0] would be "layer1"
$LayerArray[1] would be "layer2"
$LayerArray[2] would be "layer3"

I have a related question, in php/mapscript I show the user a html list
from which he/she can select layers to add to the current view, I am
writing some code but it doesn't work can somebody provide me with the
algorithm if not the code like the one given below:
if ( isset($HTTP_POST_VARS["layer"]) ) {
   echo $HTTP_POST_VARS["layer"];
   $layer = $map->getLayerByName($HTTP_POST_VARS["layer"]);
   $image = $map->prepareImage();
   $layer->draw($image);
   $image_url = $image->saveWebImage(MS_PNG,1,1,0);
}   // end of if loop
The above code doesn't work it creates a blank image, moreover if one
selects multiple layers to display then only the last one selected is
chosen.

Yes you could do this. I do a variation on this for Census data because
it is organized in directories by county and each county has a full set
of layers. So what I do is make the tileindex index the directories and
then in my mapfile I use the tileindex and DATA roads or DATA rivers.
There is an option that if I remember correctly is not well documented
or I missed it that intedexes the directories instead of the files as
records in the tileindex. I wrote some code to munge the indexes before
I found the option to do it for me. (the programmers curse - if you
can't find it, don't read the manual, just write some code :)

I'm not sure I can help much here, but I would think it would depend on
the data and how it is organized spatially.

It is most effiecnt if ALL .shp files have a shptree index, otherwise
mapserver falls back to a full scan of the file.

I got Proj from ftp://ftp.remotesensing.org/pub/proj/proj-4.4.5.tar.gz. 
I compile it
1)-with --prefix=/home/mapserver_3.5/proj-4.4.5/
./configure
make
make install (ok)
then I recompile mapserver --with-proj
./configure --with-proj=/home/mapserver_3.5/proj-4.4.5/
make (ok)
when I run ./mapserv
./mapserv: error while loading shared libraries : libproj.so.0: cannot
load share object file: No such file or directory


2)- without --prefix :
./configure
make 
make install

Evreything is fine.
Then I recompile mapserver with --proj
./configure --with-proj=/usr/local/lib/
configure: error: couldn't find projects.h or libproj.a/libproj.so in
/usr/local/lib/
libproj.a and libproj.so are in this directory BUT projects.h are in
/usr/local/include/


What am I missing ?

If you installed proj without changing the default prefix, libproj.so goes
into /usr/local/lib

You must let your system know where to find the dynamic library
libproj.so. If you are root, it may be as simple as running ldconfig, if
the path to the directory where libproj.so lives is already defined
/etc/ld.conf.

Otherwise you can edit /etc/ld.so.conf and add the path, then run 
ldconfig.

If you are not root (unlikely), the programs you run will have to rely on
the $LD_LIB_PATH environment variable to find dynamic libraries.

Just use --with-proj. ./configure is smart enough to find the headers and
libraries in /usr/local/include and /usr/local/lib, respectively. If you
want to specify a path, you should use --with-proj=/usr/local.

Jeff:

How do I set up a getFeatureInfo on a mapserver layer? I looked
on the website but did not see the particular example for this.
But I did find your email link...

Also, is there a way to slave the "STYLE" request in a WMS getMap
request to go to one or another mapfile section? For example, I
have set up a current conditions weather data server with both
a WMS and WFS interface. Since it has many hourly parameters,
I'd like to expose many possibilities to label. One convenient
way to do this might be have one weather layer and have STYLEs
for each parameter that would set the label item or symbol 
differently, requiring different mapfile blocks.
Thus one could display temperature, dewpoint, wind direction, 
etc as "styles" of weather display.  Is this possible, or must
I treat these as distinct layers?

Thanks.

Doug.

Subject: [mapserver-users] Mapscript exception from java
Message-ID: <3CADA43F.3050102@hs-harz.de>

I wanted to try out the implemented thread-functionality. I downloaded a 
nightly build today (05.04.2002).

Everything compiled well, even the java-classes were compiled without 
any error and the shared library is successfully build!

Calling the mapObj.draw() method in a java-programm crashes my jvm. I 
narrowed down the error in the mapscript_wrap.c:

--snip
imageObj *mapObj_draw(mapObj *self){
     imageObj *image=NULL;

     image = (imageObj *)malloc(sizeof(imageObj));
     if(!image) return NULL;

     image->width = gdImageSX(image->bytes);          <-- Exception
     image->height = gdImageSY(image->bytes);
     image->bytes = msDrawMap(self);
     image->imagepath = image->imageurl = NULL;

     return image;
   }
--snip

Can anyone help me out of this? Is it a mistake in the gd-library?

Second question: Swigging the nightly build to java no "errorObject" is 
produced. In 3.5 there was this thing.

Thanks in advance

There are two options... By your email I guess the 1st one you don't want to
try, but anyway:

1) Install SDO (Oracle Spatial) which has a whole spatial data support
implemented, including MDSYS.SDO_GEOMETRY type for storing the data in your
shapefiles. Compile mapserver with Oracle Spatial support and migrate your
shapefiles to Oracle using a shp2sdo program from OTN (don't have the URL
with me right now). Create the mapfile with an oraclespatial layer, and it's
done.

2) Split your data in two parts: static base layers are stored in standard
shapefiles; while dynamic layers (which your database handles) are stored in
Oracle in your private format (perhaps you have only lat/lons points and
want to see them). You will have to work with PHP (using OCI) and MapScript
to draw/query your points. Depending on your application, there's a lot of
coding ahead. If data is complex or big, expect delays for delivering
content to the web.

Hi,
I've succesfully run the Gmap and Itasca demo and managed to replace the old
shp-files with my own, but now I want to retrieve data from a database.

On the main page of MapServer it is said: "If the data has a spatial
component and you can get to it via your favorite scripting enviroment then
you can map it."

But I can't find any documentation on data from a database. How can I pass
the data on to MapServer?

I want to use Perl or PHP on Apache HP Unix. I have my spatial data in an
Oracle 8.1.6 database (not Oracle Spatial).

What  to do?
Any suggestions will be highly appreciated.

Hi Topan,

Assuming DTM is digital terrain model points in lat/lon/altitude type,
.....

You could convert this using PHP + Mapscript like following:

if ($init==1) {
// recreate the site layer
   $shpFname = "C:\\Program Files\\Apache\\htdocs\\mich\\data\\shptest";
   $shpFile = ms_newShapeFileObj($shpFname, MS_SHP_POINT);
   $def =  array(array("PROG_ID", "N", 5, 0));
   $dbfFile = dbase_create($shpFname . ".dbf", $def);
   createPoint( 14, 34, 111);
   createPoint( 33, 14, 222);
   createPoint( 10, 20, 333);
// done... cleanup
   $shpFile->free();
   dbase_close($dbfFile);
}


function createPoint($x, $y, $name){
     GLOBAL $shpFile, $dbfFile;
     // Create shape
     $oShp = ms_newShapeObj(MS_SHP_POINT);
     $oLine = ms_newLineObj();
     $oLine->addXY($x, $y);
     $oShp->add( $oLine );
     $shpFile->addShape($oShp);
     // Write attribute record
     dbase_add_record($dbfFile, array($name));
}

Createpoint adds point to shapefile and 'info' to dbf-file. You would do
this for every point of your DTM file and that's it, shapefile is
created.

Code is from list, and there are more examples like this one, so a
search could come up with a better example.

Erwin

Is there a way in php mapscript to know the adjacent lines of a given line?
Can mapscript recognize the shape's topology?
Or it just can be done with postgis or Oracle spatial server?

Subject: [mapserver-users] No errors, but no lines on output map.
Message-ID: <20020405130911.A20520@wblogan.net>

Hello,

I am just getting started with mapserver and am trying a very simple
setup to begin with.  My HTML files are modified versions of the
Itasca demo files, and so is the map file (which I've included below).

My data source is a single county's worth (Carroll county VA) of
Tiger/LINE 2000 files.  I compiled mapserver with projection support
and OGR support, and the log doesn't show any errors when I run it.
However, I don't get any lines in the output map.  I also had this
problem with a shapefile I was playing with, and think it is some sort
of extents problem.  The values for the map's extents (shown in the
mapfile) are known to fall within the county I'm messing with.
(Aren't Tiger/LINE files in lat/lon format?  The extents I placed in
my mapfile are in UTM/Meters.)  I'm trying to generate a street map of
the county, but I'm not sure I'm going about it in the correct way at
all. :)

How do I get the values I need for the map EXTENT?  I was also
wondering how to generate a reference image for the TIGER data.

BTW, mapserv takes awhile to serve the data up when I specify layer 0
in the CONNECTION arg, so it seems to be doing something with the
data.

Hi Erwin,
I wrote code to implement some of the things you suggested. If I use GET I
get all the params. like zoomsize, layers etc. in my address window of IE,
but for POST these params. do not appear in the address window.
But for both these methods when I print out the vals. of layer field I get
only the last element selected.
Here is the code I use:
if ( isset($HTTP_GET_VARS["layer"]) ) {
   reset($HTTP_GET_VARS);
   $selectLayers = explode(" ", $HTTP_GET_VARS["layer"]);
   echo "here";
   foreach($selectLayers as $val) {
      echo "$val ";
   }
}   // end of if loop
same goes if I try POST.

Pushkar,

What does $HTTP_GET_VARS["layer"] return?
What does the url look like when you use GET ?

Maybe rewrite your select list to PHP, so you can 'make' a url array
like:

LayerArrayString = "a c"

Would look something like:

<select multiple name="LayerList[]" size="5">
<OPTION value="A">A</OPTION>
<OPTION value="B">B</OPTION>
<OPTION value="C">C</OPTION>
</select>

Then you can call the LayerList-array using:

$count=count($LayerList);
for ($i=0; $i<$count; $i++) {
    echo $LayerList[$i];
    $LayerArrayString = $LayerArrayString . " " . $LayerList[$i];
}


Erwin

Hi Erwin,
I wrote code to implement some of the things you suggested. If I use GET
I
get all the params. like zoomsize, layers etc. in my address window of
IE,
but for POST these params. do not appear in the address window.
But for both these methods when I print out the vals. of layer field I
get
only the last element selected.
Here is the code I use:
if ( isset($HTTP_GET_VARS["layer"]) ) {
   reset($HTTP_GET_VARS);
   $selectLayers = explode(" ", $HTTP_GET_VARS["layer"]);
   echo "here";
   foreach($selectLayers as $val) {
      echo "$val ";
   }
}   // end of if loop
same goes if I try POST.
My html:
      <b>Select Layers to Display: </b><br>
      <select multiple name="layer" size=5>
      <option value="a">a
      <option value="b">b
      <option value="c">c
      <option value="d">d
      <option value="e">e

      <!-- comment php code for now
      <?php
      foreach($layerNames as $layerName) {
      switch($layerName) {
         case 'six_cnty':

         case '6cnty_quad':
            break;
         default:
            printf("<option value=$layerName> $layerName");
         }
      }
      ?>
      -->
      </select>

Erwin,
Thanks, it's working.
I just found out in a php tutorial that you have to use
<SELECT NAME="var[]" MULTIPLE>
for php code to work unlike perl.
This is a good tutorial for any one interested on more:

Ben,

Change your map file to :

UNITS DD
# extents for all of Virginia
EXTENT -83.682000 36.543600 -74.952000 39.769180

should fix your problem.

Subject: [mapserver-users] Mapserver Compilation Version runtime errors
Message-ID: <200204052012.PAA32758@www22.ureach.com>

Dear Map Server Users !

The opinion is appreciated on the following:

The binary distribution of mapserver comes in 

both 

gif and png versions.

I compiled the mapserver using the source code provided for 
windows 2000. The only problems encountered were:

defining explicitly

#define bcmp(s1, s2, n)	memcmp ((s1), (s2), (n))
#define bcopy(s, d, n)	memcpy ((d), (s), (n))
#define bzero(s, n)	memset ((s), 0, (n))
#define alloca( par ) malloc( (par))

and skipping some *.obj defined in the makefile , but not found 
in regex distribution.


in regex compilcation 

and replacing (as suggested in gd  comments ) *gif functions
by *png functions (there are no *Gif equivalents in gd source 
distribution).

void gdImageGif(gdImagePtr im, FILE *outFile)
{
    gdImagePng(im, outFile);
} // eof 

// 
// 
gdImagePtr gdImageCreateFromGif(FILE *inFile)
{
   return gdImageCreateFromPng(inFile);

} // eof 

in gd-1.8.4
Well, when I placed the compiled version into cgi-bin\ instead 
of precompiled binaries. It gives the error 

that it can not initialize the image.  

? What version is compiled in source distribution: gif or png, 
or anything else

? which flags I need to set to produce either gif or png version
(gif is defined by USE_GD_GIF in the source ... )

Thanks a lot

Adam, I had come across similar problems but am not sure if it was only on

I have some DRG's with collar's intact. The color values in the collar
region have essentially had a value of  20 added to them (so white inside
the color is 1, and 21 in the collar).

I want everything >= 13 to be OFFSITE.

Is there any way to do this?

Thanks Tyler.

I'm running MapServer 3.5 on Windows 2000.  I'm networked to a handful of
county servers including the web server that my mapserver files are on.

LAYER

	CLASSITEM "OWNER"
  CLASS
    OUTLINECOLOR 255 0 0

  END

END

The following works fine...

$str = "foo";
$classObj->setexpression("\"$str\"");
$layerObj->set("status", 1);

But I want to do the following, which, needless to say, does not work...

$str = "([GIS_KEY] in (\"foo\", \"bar\", \"baz\"))";
$classObj->setexpression("\"$str \"");
$layerObj->set("status", 1);


In fact, I can't even get the following to work...

$str = "([GIS_KEY] eq \"foo\")"; OR
$str = "([GIS_KEY] == \"foo\")"; OR 
$str = "([GIS_KEY] eq 'foo')"; etc.


What am I missing here? And if the "in" clause is not supported (doesn't
seem to be per the docs), would I need to do the following...

$str = "(([GIS_KEY] eq \"foo\") or ([GIS_KEY] eq \"bar\") or ([GIS_KEY] eq
\"baz\"))";

I've had a similar problem Adam, again using MapServ 3.5 on Windows 2000.
I couldn't access data on network/shared drives, only locally.   It's been
a while since I tried, but I hope someone else can shed some light on it
for us.  Any takers?

Thanks Tyler.

I'm running MapServer 3.5 on Windows 2000.  I'm networked to a handful of
county servers including the web server that my mapserver files are on.

Adam, I had come across similar problems but am not sure if it was only on
the windows platform or not.  What is your "setup" - are you using windows,
cygwin, unix and maybe you could tell us what version you are using.

Thanks, that did at least cause something to show up.  However, I
wanted to change the layer to represent landmark features, and now
nothing will show up again (same EXTENT as you gave above).  The
output of ogrinfo on the Tiger data looks like this:

INFO: Open of `web/mapserv_demo/test/data/carroll'
using driver `TIGER' successful.
1: CompleteChain (Line String)
2: AltName (None)
3: FeatureIds (None)
4: ZipCodes (None)
5: Landmarks (Point)
6: AreaLandmarks (None)
7: KeyFeatures (None)
8: Polygon (None)
9: EntityNames (Point)
10: IDHistory (None)
11: PolyChainLink (None)
12: PIP (Point)
13: TLIDRange (None)
14: ZipPlus4 (None)

Note:
When I speak of layers below, I'm talking about the argument to
CONNECTION in a LAYER definition.  E.g.,

CONNECTON "data/carroll, 0"

I have skimmed the Tiger/LINE 2000 spec (from the Census Bureau) and
have some understanding (perhaps wrong :) of how the different record
types relate.  Based on that, I thought that I should get a map of the
roads from layer 1 (CompleteChain).  However, the only way I get any
output at all is if I use 0.  If I change the layer arg to 5 and the
LAYER TYPE to POINT, I get nothing and the result is returned very
quickly unlike what happens when I use 0 which takes quite a few
seconds.

I know that it would take a comination of layers to get the names of
the landmark features (or road names, etc), but it seems like I should
get a plot of the points.

Thanks,
Ben

Subject: [mapserver-users] modifiing labels
Message-ID: <20020406003332.GA28053@extempore.otsys.com>

Greetings All,
    I would like to paint highways with the number of the interstate
placed inside an interstate shield.  The trouble that I am having is
that the data vendor has named the highways similar to "I 5".  The
"ROUTENUM" field is also populated with the 'I' as well as the actual
route number.  Is there a way that I can express that the label should
include all text after "I "?

    Another question I have relates to scaling.  I am attempting to turn
off different layers depending on the zoom level.  The trouble I am
having is that the MAXSCALE values I am pushing in do not have the
desired effect.  I am finding the thresholds are on the order of 1 - 5,
clearly not in the range of scales I am used to seeing printed on a map.
So the question is what is MAXSCALE and MINSCALE relative to?

Thanks,

Puneet,

You want to use a regular expression so in your mapfile you would say:

CLASSITEM "GIS_KEY"
CLASS
  EXPRESSION /^foo$|^bar$|^baz$/

or in php you would say something like:

$oLayer->set("classitem", "GIS_KEY");
  ...
$oClass->setexpression("/^foo$|^bar$|^baz$/");

I haven't tested this but it should be close to this syntax. Give it a
try and let us know how it goes.

This could be because the web server process does not have access to the
network drives. This could be because of access rights, or it could be
because you are using a mapped drive which only exists for you as a user
after you log in. Since the web server does not log in it does not have
any mapped drives and can only access the local drives.

Ben,

Do you want shape files for Carroll Co.? It would probably work better
than OGR. What is the tiger file name you are working with for Carrol
county?

Can you handle a big email or would you rather download it froma
website? Assume you want it :)

Subject: [mapserver-users] Mapserver and mapscript APIS for color changing
Message-ID: <200204020607.BAA11466@www23.ureach.com>

Dear Mapserver Users !

I need to change the colors dynamically for certain polygins 
and/or for layers (depends on how the image is composed). The 
mapfile provides color definition, but I would like to change 
it based on some time-dependent process.

I plan to invoke the function (integrated into mapserver after 
processing the map file) or using mapscript.  

If anyone can suggest the APIs to use for 

-> layers color setting
-> individual polygon color setting (based on the attributes in 
*.dbf file)

I will very much appreciate it.

Thanks in advance,

Alexander Shostko

It is a peculiarity of the OGR integration in MapServer vs. ogrinfo that
the layer number is different.  Ogrinfo is reporting 1 based numbers while
MapServer requires zero based indexes. so CompleteChain is layer index 0.

This is noted in the OGR-HOWTO but is somewhat unobvious.

Subject: [mapserver-users] Changing the color of a point with Mapscript
Message-ID: <000301c1da16$9fa52320$55458990@tndn151qlhf5gi>

Hi All,

I use mapscript to dynamically create a point layer with the results of a
query to a MySQL table. Once a hash table is populated from a MySQL query
the following subroutine runs:


################################################################
sub make_unlabled_points {
    my ($layer_name) = @_;

    $layer = $map->getLayerByName($layer_name);

	    my $i = 1; # site counter
	    foreach my $s (@sample_sites) {
	        $point->{x} = $s->{lon};
	        $point->{y} = $s->{lat};
	        $point->draw($map, $layer, $img, undef, undef);
	        $i++;
	    }
}
###############################################################

Given a reference to an existing layer definition in the map file a nice
field of points is rendered.

The following is an example of one of the layers commonly used:

##############################################################
LAYER
	NAME sw_sites_no_lab
	TYPE point
	STATUS DEFAULT
	DATA locations

	CLASS
		SYMBOL 3
		SIZE 3
		NAME "sample sites"
		COLOR 254 0 0
	END
END
##############################################################

The reference to the DATA being in the locations shape file is irrelevant as
the layer definition simply provides symbology. And here is my problem...I
can now do more complex queries of my underlying data and would like to
render points in varying colours reflecting value ranges. How can I do this
with mapscript? The truly dumb and stupid way would be to define various
layers with different symbology but that limits me severely and gives no
real scope for user interaction like refining the colour ramp based on the
range of values in the returned data.

Regards

Steven Hayes

Frank,

There should be a mapserv CGI executable compiled with WMS Client
enabled in the following archive from our download site:

Ahh.  I didn't see that note, and thought that 0 stood for all layers.
It does indeed work now.

Thanks Steve for responding.

As you know, I figured out the regexp solution like you also suggested...

> $oClass->setexpression("/^foo$|^bar$|^baz$/");

actually, since I wanted a full string match of many strings, I did the 
following...

$oClass->setexpression("/(foo)|(bar)|(baz)/");

it works peachy.

For now my problem is solved. However, I still can't get logical 
expressions to works, not at all. I can imagine wanting to do inequality 
operations such as...

$oClass->setexpression("(([CI] < 5) or ([CI] > 7) or ([CI] eq 
\"Puneet\"))");

but, no success. I have tried a variety of different syntactic 
constructs (including different case combinations as well, even though I 
know that the attributes are all upper-case), starting with the simplest 
possible ([CI] = 5) and failed.

I _am_ using PHP/Mapscript right now, but also re-writing the entire 
application in Perl/Maspscript.

Why are my logical expressions failing? Is there something very obvious 
that I am overlooking?

Thanks Raju, 

Because I hadn't seen any postings about the problem, I assumed that it was either a chronic case of deja vu or a mail server problem on my end.

Thanks for clarifying the problem.

Puneet,

Try something like this for the mapfile:

EXPRESSION ('[CI]' =~ /^Puneet/ || length('[CI]') < 3)
or
EXPRESSION ('[CI]' > 3 && '[CI]' < 5)

You can convert this to PHP or Perl

There is my approach which I used formerly for displaying the
dangling/pseudo nodes in ArcView:

- get the last/first point coordinate in the line
- use selectByPoint with small tolerance (if the layer is indexed, the
function would be speedy)
- exclude processed line from the result
- other shapes in the result set are adjacent lines

(For network analysis is good to preprocess these data to get faster
response.)

Hi,
I have a MrSid file I want to display as a layer in MapServer.  Does anyone 
have an interface to do that?
Thanks

I'm new to Mapserver and don't know whether there is a Mapserver
interface or not--it would be very cool if there is.  In the mean
time...

The MrSid Viewer is available for free download from the LizardTech
website (http://www.lizardtech.com).  The Windows version has the
ability to export the whole MrSID file or a portion of it as GeoTIFF
or, I think, TIFF with world files.  If you use Linux (as I do) I
suggest downloading the Windows version and running it under Wine.  At
least that worked well for me.  The Unix version of the MrSID viewer
doesn't have as many features and you can only save the currently
viewed region. :-(

BTW, there seem to be several different flavors of the viewer for the
Windows platform.  The one you want is the Standalone Viewer and the
download is 6+ Mb.

Hope this helps,
Ben

it refering to a QUERYMAP or is the QUERY object undocumented?  If so,

Ben,

In my "MapFile Reference - Mapserver 3.5" doc, it is right after the
Legend Object and imeadiately before the Join object.

Check again ...

Thanks for your suggestion, Ben.  However, correct if I'm wrong, the 
GeoTIFF format is not multi-res like MrSid.

You often get this error when you point your browser to a non-existing
.php page on a system running PHP as a cGI.  The server should return an
error 404 (not found) but the PHP CGI seems to have a bug
(http://bugs.php.net/bug.php?id=13035) and returns nothing in this case,
which explains the error 500 that Apache returns.

Try setting "log_errors = On" in your php.ini and you should (hopefully)
get a more meaningfuil error messaqge in your apache error_log that will
help figure the source of the problem.

You can add overviews to tiff files with the gdaladdo utility. Tiff files 
are large, and overviews make them larger, but improve performance. You 
should also consider ecw if you are working with grayscale images. Ecw is 
very similar to MrSID and is supported by mapserver under windows (not 
Linux/UNIX). If you are working with color, I'd suggest that you stick with 
tiff because the color in mapserver-ecw doesn't look all that great.

The MapServer parser isn't as smart as it probably could be and doesn't
have the benefit of knowing the type of data being substituted using []
or %% replacement strings. Therefore you must tell it. Try quoting
[GIS_KEY] in the expressions. That tells the parser that the value is a
string.

In fact, I can't even get the following to work...

$str = "([GIS_KEY] eq \"foo\")"; OR
$str = "([GIS_KEY] == \"foo\")"; OR 
$str = "([GIS_KEY] eq 'foo')"; etc.


What am I missing here? And if the "in" clause is not supported (doesn't

Hi,
I am trying to display query results, I am using code from the gmap demo.
In short I do this, the gmapDumQueryResults() is unchanged from gmap demo.
In my map file I have:
   METADATA
      "DESCRIPTION" "Buildings"
      "RESULT_FIELDS" "Area Perimeter"
   END
Area and perimeter are the attribs I want displayed.
When I query a point in my map I get:
Nothing found at query location.  even though I click on a layer.
This happens because the numResults val. in gmapDumpQueryResults() is
zero:
        $numResults = $oLayer->getNumResults();

        if ($numResults == 0)
            continue;  // No results in this layer

php code:
if ( isset($HTTP_POST_VARS["mode"]) ) {
   $nClickPixX = intval($HTTP_FORM_VARS[mapa_x]);
   $nClickPixY = intval($HTTP_FORM_VARS[mapa_y]);
   $dfWidthPix = 600;
   $dfHeightPix = 500;
   $dfMinX = $map->extent->minx;
   $dfMaxX = $map->extent->maxx;
   $dfMinY = $map->extent->miny;
   $dfMaxY = $map->extent->maxy;
   if( $HTTP_POST_VARS["mode"] == "query") {
      $nClickGeoX = GMapPix2Geo($nClickPixX, 0, $dfWidthPix, $dfMinX,
$dfMaxX, 0);
      $nClickGeoY = GMapPix2Geo($nClickPixY, 0, $dfHeightPix, $dfMinY,
$dfMaxY, 1);

      $oClickGeo = ms_newPointObj();
      $oClickGeo->setXY($nClickGeoX, $nClickGeoY);

      // Use '@' to avoid warning if query found nothing
      @$map->queryByPoint($oClickGeo, MS_SINGLE, -1);
      gmapDumpQueryResults();
   }
}   // end of if loop
Do I need to call some other functions.

The  mapserver reference I am using also has only Querymap between Join and Legend.  Is there more than one version of the docs?
I am using the docs from http://mapserver.gis.umn.edu/doc/mapfile-reference.html  The query object sounds like something I am looking for.

Pushkar,

You MUST also have a TEMPLATE statement in the LAYER or CLASS definition
or that layer will NOT be queried. It is sufficent to say

QUERYMAP signals the start of a Query object.
I think that IS what you are looking for.

Steven,
Thank you for your response but it didn't work either.
Just to make sure "RESULT_FIELDS" must contain the attribs. name, right?
In doing a query do I need any other function besides
gMapDumpQueryResults() in order to display the info. about the layers?

Hi all,

I noticed today that my application breaks when getting the mapserv WMS capabilities document in mapserv3.5.  There appears to be a reference to:

http://www.digitalearth.gov/wmt/xml/exception_1_0_0.dtd

This no longer appears to be a valid url.  I realise that http://www.digitalearth.gov/wmt/xml/exception_1_0_1.dtd is valid, but this isn't being requested.


Using this url:
http://maps-dev.socialchange.net.au/cgi-bin/mapserv?map=mapfiles/geoscience10m.map&WMTVER=1.0.1&request=capabilities&LAYERS=

I get...................

<!DOCTYPE WMT_MS_Capabilities SYSTEM "http://www.digitalearth.gov/wmt/xml/capabilities_1_0_0.dtd"
 [
 <!ELEMENT VendorSpecificCapabilities EMPTY>
 ]>  <!-- end of DOCTYPE declaration -->

Is this dtd going to be reliable or is it now not being used?

Cheers,

Trem

Pushkar,

The field names are case sensitive. You must match the case spelling of
the field names. One the shp file in ArcExplorer2 and check the case of
the names. You can not rely on "dbfdump --info file.dbf" from the Perl
utility.

thanks to sw and sdl, I now know how to do this (will try it out 
tomorrow at work). one thing though... the documentation makes a very 
cursory mention of this peculiarity without really pointing it out...

Specifically, I could find only one passing references to attribs in 
shape files at http://mapserver.gis.umn.edu/doc/mapfile-reference.html

see the '[LANGUAGE]' eq 'FRENCH' bit... that escaped me completely, and 
now is noticeable only because I have been educated about it.

Nonetheless, many thanks,

Chris,

This might be just trivia.

I picked up a copy of Mapping Websites: Digital Media Design (site maps, 
not map sites) last week.

<http://shop.barnesandnoble.com/booksearch/isbnInquiry.asp?isbn=2880464641>

In Chapter 3 it contains screen shots of an application called NoteCards 
developed by Xerox PARC. The authors consider it one of the earliest 
hypertext systems and a predecessor to Apple's HyperCard. The images in the 
book are from a presentation at Hypertext '87 and they show map images 
being displayed as the result of selecting a hyperlink.

The researchers giving the paper "Hypertext Habitats: Experience of Writers 
in NoteCards" were: Randall H. Trigg and Peggy M. Irish. Additional 
developers were Frank Halasz and Tom Moran.

Message-ID: <1V85WUTSTORN4Y75KJTQSMVP3X623Y1V.3cb169f6@rogers>

Hi all,

Hope this doesn't sound dumb, but am trying to understand how mapserver operates with CGI calls with multiple users.
Have only been working with web map servers for a short period  ( 2 weeks) so some of the concepts are a bit new.

I have used a common map file to set up Mapserver for all users, but the data each user requires is different.
I have been successful in using a URL to change the data string for the layers defined in a common map file, 
so I can customise the layer being displayed based on a variable in my app.

Do I need to pass these parameters every time that I make a call to MapServer?

One reference said that MapServer is stateless, so does this mean that once it renders and image it forgets what it has done
for that user,  and thus I would assume that it needs to have all parameters that are different to the Map file defined on each call? 

It would be easy enough for me to test this for one user, but what about with multiple sessions where each user has a different data value would require a bit more effort.

Oic.  I wondered if that was the case because I'm looking at the same
docs as Robert and only found QUERYMAP.

The only problem is that I don't see why you would nest a JOIN inside
a QUERYMAP object.  Looks like QUERYMAP is simply a way to hilight the
results of a query, whereas a QUERY object would determine how the
query is performed.  I do see that a LAYER can have a TYPE of "query"
so perhaps that's what you nest a JOIN in.

Thanks,
Ben

Message-ID: <20020408070900.B11620@wblogan.net>

I've been searching the docs and list archives, but haven't found much
on getting the Python Mapscript wrapper to work.  I changed to the
mapscript/python directory, ran python, and tried to import
mapscript.py, but got the following error:

Python 1.5.2 (#1, Mar  3 2001, 01:35:43)  [GCC 2.96 20000731 (Red Hat
Linux 7.1 2 on linux-i386

>>> import mapscript
Traceback (innermost last):
  File "<stdin>", line 1, in ?
  File "mapscript.py", line 2, in ?
    import mapscriptc
ImportError: No module named mapscriptc

Here's the contents of the directory:

CVS
examples
mapscript.i
mapscript.py
mapscript.pyc
mapscript_wrap.c

As you can see, there is no mapscriptc.* .  From the messages in the
list archives is appears that I need to compile mapscript_wrap.c into
mapscriptcmodule.so (since I have a mapscript_wrap.c, I'm assuming
that I don't need to run SWIG--if so I'll have to install it first).

I ran

gcc -c mapscript_wrap.c -I/usr/include/python1.5 -o mapscriptcmodule.o

without any errors.  I then ran

ld -shared mapscriptcmodule.o -o mapscriptcmodule.so

also successful.  However, now I get the same error as the OP:

Python 1.5.2 (#1, Mar  3 2001, 01:35:43)  [GCC 2.96 20000731 (Red Hat

  File "mapscript.py", line 2, in ?
    import mapscriptc
ImportError: ./mapscriptcmodule.so: undefined symbol: ms_error

Norman Vine responded to his post and attached a setup script to link
the module with the necessary mapscript libraries, but the list
archive software won't let me download it.

I tried

ld -o mapscriptcmodule.so mapscriptcmodule.o -shared ../../libmap.a

and it seemed to work, but now I get this error:

Python 1.5.2 (#1, Mar  3 2001, 01:35:43)  [GCC 2.96 20000731 (Red Hat

  File "mapscript.py", line 2, in ?
    import mapscriptc
ImportError: ./mapscriptcmodule.so: undefined symbol: gdImageCreate

I have a feeling this could go on for a while.  As you can probably
tell, I don't know too much about building libraries. :) Can anyone
help me out?  BTW, I'm using MapServer 3.5 and you can see my system
setup from the errors above.

Thanks,
Ben

Puneet,

You could help everyone if you would do a mini howto page on wiki.
It could be just a bunch of examples of various expressions it a short
explaination of what is important about each. I would then be easier to
point other people to it in the future.

Anyway, glad your up and running.

Correct, they are not multi-res however nothing says that you can't create multiple catalogs of multiple resolutions.
Dating back to an older post (Ed M.) to the group: if a 1' pixel takes 20MB a 2' pixel only takes 5MB & etc.
We did this for TIFF & WLD files using ImageMagick & Perl and produced 2', 4', 8', & 10' pixel versions of our original 1' photography and are very pleased with the result and speed of rendering. The only special thing that needed done during the map creation is to have a minscale & maxscale for the layers so the appropriate layer is displayed.
If you can use it and are willing to hack the Perl code that has been written particular to our site let me know and I'll send it to you.

Steve et a. -

That's not quite correct.  The Web server runs under a user security context, like everything in Windows 2000.  If you're running a Web server with a site that permits anonymous user access (as most do), your server will have a LOCAL user account named IUSR_<machinename>; for example, if the machine is named FOO, then there is a local user account named IUSR_FOO that is used by the server for anonymous access.

That means that the MapServer CGI runs as if it were run by the logged-in user IUSR_FOO, and it only has access to things that IUSR_FOO can access.  The default setup is for IUSR_FOO to be created as a local machine account, NOT a domain account - it's an account that only exists on the Web server machine.  As a result, since it's a local machine account, it has NO ACCESS to network resources.  You have to be a domain user to get those.  Therefore, you won't be able to see any network data files.

You can change the Web server's user account to be a domain user account, and then you can get access to domain resources.  Remember that this is a two-edged sword.  The reason the default account is a local machine account is to prevent security problems; the default setup only permits access to the local machine, so the risk from a Web attack is minimized.  If you change that account to a domain account you potentially expose your entire domain to an attack.  There's nothing wrong with that; it just means you are increasing the benefits and increasing the risk, and you need to manage the security situation appropriately.

This could be because the web server process does not have access to the
network drives. This could be because of access rights, or it could be
because you are using a mapped drive which only exists for you as a user
after you log in. Since the web server does not log in it does not have
any mapped drives and can only access the local drives.

Aaron,

How do you plan to use this?
Do you need dynamically generated postscript? or are you just looking to
embed a high quality image in another document?

Can you PDF output that you print to a postscript file?

Message-ID: <3DFF131E4E6D2D4198CDD758F35A5353010AB9E7@postoffice.GASAI.Com>

Many thanks to Frank Warmerdam for helping me figure this one out.
Basically, there doesn't appear to be anyway to specify more than one
OFFSITE value in the mapfile.

Ultimately, what he suggested, which worked great, was to use classes to
define the colors that I want to show. Anything not specified in a class
doesn't render, and is hence transparent.

For this set of images, this was fairly simple, since they only contain 13
color (0 - 12). For a more complex set of images (or a less consistent color
set), this would be a big pain.

If anyone knows how to set a color to be "transparent" outside of the
OFFSITE parameter, that would be a cool addition to this. One could specify
a range of values as a class and color them as transparent:

  CLASS
    EXPRESSION ([pixel] >= 13 AND [pixel] <= 255)
    COLOR [transparent] #whatever [transparent] is...
  END


For reference purposes, the resulting map file is below:

LAYER 
  NAME "DRG" 
  MAXSCALE 500000
  STATUS default
  TILEINDEX "DNR_GeoDISC\quadindx\qdrpw924\qdrppoly.shp"
  TILEITEM "Location"
  TYPE RASTER
  CLASS
    EXPRESSION ([pixel] = 0)
    COLOR 0 0 0
  END
  CLASS
    EXPRESSION ([pixel] = 1)
    COLOR 255 255 255
  END
  CLASS
    EXPRESSION ([pixel] = 2)
    COLOR 0 150 165 
  END
  CLASS
    EXPRESSION ([pixel] = 3)
    COLOR 206 0 16
  END
  CLASS
    EXPRESSION ([pixel] = 4)
    COLOR 132 65 33
  END
  CLASS
    EXPRESSION ([pixel] = 5)
    COLOR 206 235 156
  END
  CLASS
    EXPRESSION ([pixel] = 6)
    COLOR 140 48 132 
  END
  CLASS
    EXPRESSION ([pixel] = 7)
    COLOR 255 235 0
  END
  CLASS
    EXPRESSION ([pixel] = 8)
    COLOR 165 227 231 
  END
  CLASS
    EXPRESSION ([pixel] = 9)
    COLOR 255 186 189
  END
  CLASS
    EXPRESSION ([pixel] = 10)
    COLOR 222 178 214 
  END
  CLASS
    EXPRESSION ([pixel] = 11)
    COLOR 214 211 214
  END
  CLASS
    EXPRESSION ([pixel] = 12)

I thought I'd keep adding libraries to ld's commandline until I didn't
get undefined symbol messages anymore.  I got to

ld -o mapscriptcmodule.so mapscriptcmodule.o -shared ../../libmap.a /usr/local/lib/libproj.a /usr/local/lib/libgdal.1.1.so

and then when I tried to import the mapscript module, Python gave this
message:

Any suggestions?

Well, only the mechanism has to be proven. Once tested it can be used
for multiple users: Template substitutions can be used to exchange 
parameters between cgi-binary and web browser. Something like 
layer1_data=someshape in the CGI parameter string will be picked up by
the mapserver whic in trun will replace any occurence of [layer1_data]
in a template by "someshape".

On the other hand you may have a look at the SAVEMAP feature
(http://mapserver.gis.umn.edu/doc/cgi-reference.html)

Therewith you can store a new mapfile (for a session) and only have to
ping-pong the mapfile name between server and browser.

Regards,

        Frank

good idea. I added a long-ish page at PHPMapScriptMySQLShapeFiles

(got carried away) under a meta heading of
DevelopingApplicationsWithMapserver at

rver

the note about character fields in logical expressions is bold-italics
(couldn't figure out a way to color the text red or something using wiki).
will add more to it as a complete, step-by-step primer for developing a full
app with session management, user auth, etc., as time permits.

hope this helps someone.

Subject: [mapserver-users] PNG raster tiles on mapserver 3.5
Message-ID: <OFB94541D2.0329D800-ON85256B95.00633483@irm.r9.fws.gov>

Hi Folks,
      I successfully implimented a raster tile of geotiff files (24k USGS
drgs) on an internal web server , and then tried to impliment the same data
layer as a png tile ( less hard drrive space available on the planned
external server) with both .wld and .pgw files (copied from the tfw files
that came with the drgs).  The png tile does not display at all.

The only difference in the png layer is that I had edited the location item
in the dbf file of the shape file generated by gdaltindex (Great tool!) for
the tiff image tile so that it now points to "image.png" instead of
"image.tif" .  Does this need to point to "image.wld"?   I am using
mapserver 3.5 on a Red Hat 7.2 box with GDAL 1.1.6, Proj-4.4.5.  I have
tried compiling --without-png  , no difference.

I have a map with certain lat/lon coordinates marked as sites.  I would like
users to be able to click on the map and have information for the nearest
site become highlighted.  To do this, I have converted the mouse click
coordinates to lat/lon coordinates which are mapped.  Then I am planning on
calculating for each site, the distance between the click and the site, and
storing the remembering the closest one.  Is there a quicker way to do this?
Would it be beneficial to use the distanceToPoint function in mapscript?

Hello,

There is a known bug in the php4.0.6 dbase_replace_record function.  It
has been fixed in php4.1.2, and you can get a phpmapscript dll for that
version on our site at:

Scott:

I've resolved the same situation doing the following with php-mapscript:

1. Get the user's click
2. Get the desired layer
3. Turn it on
4. Create a point Object with the user's click
5. Make a querybypoint, single, and with a medium tolerance.
	- It will find the nearest point -
6. Create a new shape with the new found point

My code looks like this:
(If you have questions on this, you can mail me)

$layer=$map->getLayerByName("transformadores");
$layer->set("status",1);

// 
To convert pixel coordinates to map coordinates:
$factor=($frm["maxx"]-$frm["minx"])/$ancho;
$px=$frm["minx"]+($ZOOM_x*$factor);
$py=$frm["maxy"]-($ZOOM_y*$factor);
// 
Create the point object:
$oPoint = ms_newPointObj();
$oPoint->setxy($px, $py);
// 
Make the query over the layer
@$results=$layer->queryByPoint($oPoint,MS_SINGLE,1000);
$oRes = $layer->getResult(0);

$map->setextent($frm["minx"], $frm["miny"], $frm["maxx"], $frm["maxy"]);
// 
If there is no points:
if($oRes=="") printf("There is no points near...");
else{
// 
Create the shapefile
	$layer->open($layer->shapepath);
	$oShape = $layer->getShape($oRes->tileindex,$oRes->shapeindex);
	$nuevo_id=$oShape->values["A02ID"];
	$nueva_long=$oShape->values["A02LONGITU"];
	$nueva_lat=$oShape->values["A02LATITUD"];
	$shpFname = $CFG->tmppath . "ali_" . session_id();
	$shpFile = ms_newShapeFileObj($shpFname, MS_SHP_POINT);
	$dbfFile = dbase_create($shpFname.".dbf", array(array("ID", "N", 10, 0)));
	include("funciones_shp.php");
	$campos=dbase_numfields($dbfFile);
	createPoint($nueva_long, $nueva_lat, $nuevo_id, $shpFile, $dbfFile);
	$shpFile->free();
	dbase_close($dbfFile);

	$shpFname = $CFG->tmppath . "ubi_" . session_id();
	$shpFile = ms_newShapeFileObj($shpFname, MS_SHP_POINT);
	$dbfFile = dbase_create($shpFname.".dbf", array(array("PROG_ID", "N", 5, 
0)));
	$campos=dbase_numfields($dbfFile);
	createPoint($px, $py, 1, $shpFile, $dbfFile);
	$shpFile->free();
	dbase_close($dbfFile);
}


Hope this helps.

Sounds to me like your on the right path. If you use a buffer on the pick point to select any nearby points and then use distanceToPoint to decide which is closest.

hi,
The above is a function name for map object, there is also
getlayersdrawingorder().
I used getlayers... successfully but when I use setlayers.... I get the
foll. error:
Fatal error: Call to undefined function: setlayersdrawingorder() in
/rstc/user1/erc/pushkar/gis/mcrgdl/view3.php on line 75

Here is my code:
   $layerOrder = array ();
   $layerOrder = $map->getlayersdrawingorder();
   $noOfLayers = count($layerOrder);
   $tmp = $layerOrder[$noOfLayers-1];
   $layerOrder[1] = $tmp;
   $layerOrder[$noOfLayers-1] = 1;
   /* to debug
   foreach($layerOrder as $val) {
      echo "$val ";
   }
   echo " and  ";
   echo is_array($layerOrder);
   */
   $r = $map->setlayersdrawingorder($layerOrder);
These functions were not documented under mapscript I found them in the
mailing list archive
What I am trying to do is change the order of layers being drawn, can
anybody give me the algorithm to do this and the related functions, I am
new to mapscript.
Thanks,

Hi,
We would like to display img files and already doing so using gdal
compiled with mapserv.
However we have multispectral img files with say 7 or more bands. We want
to be able to display the bands we choose e.g. we should be able to say:
band 2 - R
band 4 - G
band 7 - B
Is this possible, if so where can I find more info. on this?

Thanks for your replies.  This is an interesting experience participating in a list as a complete newbie.

Form the replies, I understand that Mapserver doesn't maintain knowledge of each users current state, so it means that any changes to a map template need to be made for 
each call.  No great problem.  Alternatively I could use the SaveMap call to save the current settings in a temporary Map file for use in that user-session.  At one point I thought I 
would have to generate the Map file dynamically prior to calling MapServer, so both of these options are much slicker.

I thought that other web servers like MapExtreme and ARCIMS spawned new instances for a user/ session and built on previous changes, but thus had the potential to bog 
down under load.  MapServer's stateless approach avoids this load, but does it have the disadvantage that it needs to redo operations like filters each time?

My app has about 1500 farmers who each want to look at only their farm.  There are 3 master tables of farm data: paddocks, harvested areas and labels, each with about ~
30,000 records.  Each record in these tables is tagged with the farm number.

I have been able to change mapfile data parameters using a URL OK, so I can allow each farmer to look at only their data by pre-processing the master table and splitting it into 
separate farm tables that have the farm number as part of the file name, and changing the data reference for the farm layer for each farmer at run-time.

Another option is to filter the master table in MapServer and change the filter string based on farm number.

While the first option is messy terms of the number of files, it is fast.  The filter option looks neater, but I am cautious that it will load the server substantially when a large number 
of farmers are using it as I gather that the filter has to be applied in each call.

Does anyone have any comments on the performance of filters  and the load it places on the server?  The 3 master shape files are about 9MB each versus  about < 10KB each 
for the shape files for each farm.

Thanks 

R

It is known error in the php-dbase modul. You have two possibilities:

1. patch the current dbase.c code according to attached document and
recompile php.
2. use newer version of PHP where this error has been already fixed (PHP >=
4.1.)

Hi list,

beeing confronted again with mapobjects mapping facilities I saw that they have very nice splined text.

As far as I know this is not possible with mapserver. Would this be something for a feature request?

Hi,

I have a simple question: which advantages I have if I use mapserver in a
unix environment instead in a windows enviroment?

In other words, are there more disadvantage if I use a windows environment
(instead unix)?

Thanks

What if your master shapefile(s) where created as a tile index that
pointed to the individual farm shapefiles. If you included an item in the
tile index for the farm number, you could set the index as a normal
polygon layer and query against that item to quickly set the extents for a
particular farm and then also have a layer that uses the index as a true
tile index which would then point to the shapefiles of the individual
farms. When doing a spatial query the tile index will limit the query to
only the individual farm (roughly depending on shape) and an attribute
query could be forced to query only the shapefile for a particular farm
by setting the data for the layer to the individual shapefile that holds
data for that farm. That should be less messy and still increase the
speed.

It seems to me that your php_mapscript is missing the function
setlayersdrawingorder ... we are using this function in php_mapscript
(with both PHP 4.0.6 and PHP 4.1.2), it was added to cvs around
October/November last year so make sure that you have a recent
mapscript/mapserver.  Check the output of phpinfo(); after
dl("php_mapscript.so"); to see what the date and version numbers are

hi,
The above is a function name for map object, there is also
getlayersdrawingorder(). I used getlayers... successfully but when I use
setlayers.... I get the foll. error: Fatal error: Call to undefined
function: setlayersdrawingorder() in
/rstc/user1/erc/pushkar/gis/mcrgdl/view3.php on line 75

Here is my code:
   $layerOrder = array ();
   $layerOrder = $map->getlayersdrawingorder();
   $noOfLayers = count($layerOrder);
   $tmp = $layerOrder[$noOfLayers-1];
   $layerOrder[1] = $tmp;
   $layerOrder[$noOfLayers-1] = 1;
   /* to debug
   foreach($layerOrder as $val) {
      echo "$val ";
   }
   echo " and  ";
   echo is_array($layerOrder);
   */
   $r = $map->setlayersdrawingorder($layerOrder);
These functions were not documented under mapscript I found them in the
mailing list archive What I am trying to do is change the order of
layers being drawn, can anybody give me the algorithm to do this and the
related functions, I am new to mapscript. Thanks,

I'm trying to setup the imsemu perl script with nightly (Apr 09) build of
mapserver and I'm getting the following error:

This seems to stem from the fact that Class:mapObj in mapscript.pm nolonger
includes a projectionobj in its BlessedMembers

Is this being intentionally left out and the perl script for ArcIMS
emulation need to be rewritten, or is my setup not quite right in some other
area? I'd install 3.5 of mapscript but that means downgrading other files
(PHP) to previous versions. Any other ideas.

Message-ID: <5.0.0.25.2.20020409162149.01991990@pop3.wish.nl>

Hello,

I've got a server online with mapserver 3.5 (stable release) and php4.0.x. 
I've installed php as DSO module in apache. Yesterday the systemadmin 
noticed that the current version of php4 has a major bug (the famous upload 
bug). So he wants to upgrade php4 to php4.1.2.

Today i downloaded the nightly package of mapserver and php4.1.2 and 
installed everything local. php is now installed as CGI, but this is not 
ideal, cause my other php scripts are executing slow when accessed with a 
HTTP/1.1 browser. For example:
===begin.php===
<?
#!/usr/local/apache/cgi-bin/php
if($todo=="go")
{
         header("Location: pagina.php");
         exit;
}
?>
<A href="begin.php?todo=go">test</a>
============

===pagina.php===
<?
#!/usr/local/apache/cgi-bin/php
header("Location: begin.php");
exit;
?>
==============
When you click on the "test" link in "begin.php" it takes a whopping 6 
seconds to execute when using a HTTP/1.1 browser (HTTP/1.0 goes smoothly).

What should i do? I can't take the major performance hit on my scripts, i 
also can't keep a server with a major bug online.

Best regards,
- Twan

Can I do that by CGI calls?

Twan,

You can have BOTH a DSO module for your regular scripts and a CGI for
mapserver.

Install PHP without mapscript as DSO module.
Build PHP CGI with mapscript and copy it to the /cgi-bin directory
Change the extension for mapscript files to something like .php4 or
.phtml and configure Apache to run them as CGI

I think there is more info on wiki and the list archives.

Dear mapserver users,

is there a way to obtain the OID(s) of the selected features when
using spatial queries (e.g. the GMap identify tool) in PHP mapscript?

I tried to specifiy "OID" in "RESULT_FIELDS" metadata entry, but
nothing was returned (other fields are returned just fine).

This would make it easy to edit feature attributes using the PHP
Postgresql functions.

Thank You

I'm able to query the table okay too from psql.  Has anyone else built the

The only three disadvantages I have to deal with are:
-Buying a server with Windows 2000 usually costs more.
-For some things you have to purchase software in order to compile or build
your own mapserver, etc. executables on Windows.
-One image format (ECW) that we use requires a software developers kit

Hi,

I have a simple question: which advantages I have if I use mapserver in a
unix environment instead in a windows enviroment?

In other words, are there more disadvantage if I use a windows environment
(instead unix)?

Thanks

Our experience has been that:
1) Linux is cheaper if not altogether free.
2) Apache, Perl, libtiff, gd, PHP is usually installed as part of the
system and if it isn't it seems to install easier than on other platforms.
3) A lot of the system commands built into *n*x are not as readily
available on other platforms, ie. find & cron. Which may not seem like
much to start with but sure helps when deleting those pesky temporary files.
I would suspect there is a work-a-round or "add-on" that can be purchased
to fix some of the above situations, however the more I work with it the
more I realize how much is built-into the system that I take for granted.

Stefano -

A LOT depends on what operating systems you are experienced with and able to support.  As has been mentioned, Windows doesn't include many of the development tools that come with Unix.  But if you are already a Windows operation you're going to have those tools already.  If you don't, it's not worth buying and learning them.

The skill and expertise associated with running either Windows or Unix is VERY important for any Web server operation.  If you know how to use and manage one system better than the other, that's likely to be the better choice.

We run MapServer on Linux and Windows 2000, and they're mostly (in my opinion) just different.  Each has advantages and disadvantages and neither one stands out as clearly better than the other.

I am trying to add a symbol (say, a filled circle) and a text dynamically
onto a map with provided lat-long. Can I do that without using mapscript?
Can I do that by CGI calls?

I am very new to Mapserver and am sorry if this question is trivial.

Thanks for helping

ed makes the most sensible points here... 

there are a couple of issues though... and since no one else has mentioned
them, I am wondering if I am wrong in assuming thus --

- If you want to use Perl/Mapscript, it has not been known to compile and
run well on Windows.

- If you want to use PHP/Mapscript, you have to make sure your Apache is
capable of dynamically loading the php_mapscript.dll... in most cases (at
least that's what I did), one just grabs the pre-built Apache binary from
apache.org website, and that is built so it can't load dlls dynamically.

and just to counter one of ed's assumptions... we are a primarily windows
operation, however, I think only one machine in the entire company has the C
compiler loaded. All *nix boxes by default have the compilers installed.

my mapserver is running on a red hat box, and I do my application
development on a Windoze 2k connected to the mapserver box that is sharing
its drives using Samba. I use jEdit (from jedit.org) for development, and I
can take the scripts home and work seamlessly on my iBook at home using
jedit.

Hi Patricio,

Think that your width/height ratio is different then the one in your
map-file, so it will be 'adjusted' to that ratio.

Also read the following:

This happens when you havent compiled mapserver without postgis
support.  You have to explictly
tell mapserver to add in support.

When you "./configure", you should do it like:

./configure  --with-postgis=/usr/bin/pg_config

Your pg_config program maybe in a different location.  pg_config tells
mapserver where the postgresql include and lib directories are.

You should check your configure log and see if you specified where
pg_config is correctly and that configure found it sucessfully.

Hi all,
I am trying to query my maps using php/mapscript. I am using the function
GMapPix2Geo to convert the mouse coords. clicked to georef. coords.
However the conv. coordinates of the locn. clicked is different from those
shown in arcview.
How do I choose the extent of the map, I searched the archives but didn't
find any. Right now I go to arcview and put my mouse on the farthest
positions of the shapefile, and write down the values arcview displays on
the top right.
Thanks,

Pushkar,

It is very important that you match the aspect ratio of your map extents
to the aspect ratio of the image. For example on my map at
http://swoodbridge.com/web2/nmap which has the whole world displayed
which everyone knows is EXTENT -180 -90 180 90 and my image is 600X600
so what to we have:

360         600
---  is to  ---  or 2 to 1 this is BAD
180         600

the aspect ratio need to match! so I changed my map to
EXTENT -180 -180 180 180 so

360         600
---  is to  --- or 1 to 1 this is GOOD
360         600

This also has implications if you want to allow your user to change the
size of the image and they don't maintain the aspect ratio match.

There is code in the RectObj in phpmapscript to help manage this. Or you
can write your own rescaling code like I did before I found the the
$oRect->fit($width, $hieght) method.

Hi Folks: Here we go again, more talk of a user group meeting. In order
to seriously consider putting something together
we need to understand the interest level amongst you folks. Please drop
me a note with answers to the following:

1) Would you be interested in attending a MapServer users group meeting
in St. Paul, Minnesota sometime in the fall
(Sept/Oct) of 2002?

2) If yes, would you be willing to pay (approximately $300 to $400) in
order to fund such a meeting?

3) If interested, what types of events and/or presentations would be
most useful for you and your organization?

Again, we're just trying to get a handle on potential demand. I
personally would really like to see this happen. If you're
not interested for whatever reason, let us know that as well. Thanks!

Hi Folks: Here we go again, more talk of a user group meeting. In order
to seriously consider putting something together we need to understand
the interest level amongst you folks. Please drop me a note with answers
to the following:

1) Would you be interested in attending a MapServer users group meeting
in St. Paul, Minnesota sometime in the fall (Sept/Oct) of 2002?

2) If yes, would you be willing to pay (approximately $300 to $400) in
order to fund such a meeting?

3) If interested, what types of events and/or presentations would be
most useful for you and your organization?

Again, we're just trying to get a handle on potential demand. I
personally would really like to see this happen. If you're not
interested for whatever reason, let us know that as well. Thanks!

Steve

Pushkar,

You might want to use shapechk.exe if you want to get the extents of a
shapefile.

Look for info at:
http://www.dnr.state.mn.us/mis/gis/tools/arcview/tipsheets/Tip5.html
And download shapechk.exe from:
http://www.geocities.com/SiliconValley/Haven/2295/howto_shapechk.html

Subject: [mapserver-users] extents of the map, query in php mapscript

Hi all,
I am trying to query my maps using php/mapscript. I am using the
function
GMapPix2Geo to convert the mouse coords. clicked to georef. coords.
However the conv. coordinates of the locn. clicked is different from
those
shown in arcview.
How do I choose the extent of the map, I searched the archives but
didn't
find any. Right now I go to arcview and put my mouse on the farthest
positions of the shapefile, and write down the values arcview displays
on
the top right.
Thanks,

Steve,

I was looking at your mapplet code and found it does not support PNGs.
Neither does DM Soln's Rosa applet.

Searching through the list archives, I found the following message from July
2001.

==========
I have a version of Steve's mapplet that does support PNG.  Currently, I'm
working finding a preprocessor that will help make the PNG mapplet code
available to everyone.

If you would like, I could forward to you the PNG libraries and mapplet
source code.  All you would need to do is compile the source and put all the
class files in a web accessible directory.

============

could you, or someone else, shed more light on this? Is there a version of
either of these Java applets that does work with PNGs? if not, what would it
take to compile that support in?

Many thanks,

Hi Steve,

Of course we (DM Solutions) would be glad to see such a meeting happen. 
So please count us in!

BTW, we're planning to be at the GIS conference that will be taking
place in Ottawa in the second week of July... and we were thinking about
setting up some kind of MapServer get-together event around the
conference.  So MapServer users who are planning to attend this
conference should keep this potential event in mind.

Also, talking of conferences, this week the GeoTec 2002 is taking place
in Toronto (Canada).  This afternoon, Paul Ramsey, Frank Warmerdam and
Dave McIlhagga gave a very interesting set of presentations on Open
Source technologies, with a bit of focus on MapServer and PostGIS (of
course!).  And tomorrow (Wednesday) Dave is giving another presentation
on Open Standards with a focus on implementations using MapServer... I
guess it's a bit late to announce this, but if you happen to be in the
conference (and read your mail in time) then please stop by to say Hi
(13:30, room 206b)...

Daniel

I have modified the mapserver code to enable setting bands for RGB. If you
are interested in it, I would send you a copy. I am planning do more things
around it but today the conversion to 8-bits images heavily depresses the
output quality. Probably it would be better to use pre-processed the 8-bits
images for web presentation before the fullcolor output is enabled for
MapServer.

Steve, do you plan to incorporate bands selecting an other image-processing
functions to MS in future?

Perhaps no-one saw my last posts?  Or does no-one know what to do?

I'm trying to get the Python Mapscript module to compile/link.  I have
run the following commands:

gcc -c mapscript_wrap.c -I/usr/include/python1.5 -o mapscriptcmodule.o

ld -o mapscriptcmodule.so mapscriptcmodule.o -shared ../../libmap.a /usr/local/lib/libproj.a /usr/local/lib/libgdal.1.1.so

and then when I tried to import the mapscript module, Python gave this
message:

Python 1.5.2 (#1, Mar  3 2001, 01:35:43)  [GCC 2.96 20000731 (Red Hat

ImportError: (?d at R6/lib/libX11.so.6: shared object not open

Can anyone tell me what I am doing wrong, or is the Python module just
broken?

Subject: [mapserver-users] Zooming with Mapscript
Message-ID: <3CB41DD6.7020905@maich.gr>

Hello,

I am a new user to mapserver as well as this list. I am using the tcl 
mapscript interface to play with maps. I am able to draw a map...

My question, as I am trying to wade through the mapscript methods is how 
to pan and zoom a map..
The following draws a map.. (from the msworkbench code..)

set mapFile kaz_34.map
set map [mapscript::mapObj -args $mapFile]
set img [$map prepareImage]
for {set i 0} {$i < [$map cget -numlayers]} {incr i} {
	set layer [$map getLayer $i]
	mapscript::layerObjRef $layer draw $map $img
}
$map drawLabelCache $img
mapscript::labelCacheObjRef [$map cget -labelcache] freeCache
mapscript::msSaveImage $img  "$mapFile.gif" 1 1
mapscript::msFreeImage $img

I assume that the mapobject has to be re-configured (zoomed/panned) and 
re-drawn...

I could probbaly cross ref a perl example...

Sincerely,
nicolas boretos

Ben,

My recommendation is that you build the Python mapscript module
using Python distutils rather than manually compiling.

Here is a great intro document to building Python extension mods.
An hour or so of reading this will reward you many times over:

   http://www.python.org/doc/current/ext/ext.html

Next, upgrade to Python 2.1+ so you can use the newest Python
distutils.  Read all about distutils at:

   http://www.python.org/doc/current/lib/module-distutils.html

Steve Lime has written a setup.py file that should be included
in your Python mapscript source.  After reading the documents
I've referenced, you'll be able to adapt this setup file to
your own needs and will build the module easily.

Hope this helps you.  I've only built Python mapscript on Win32
so don't have any Redhat specifics.

cheers,
Sean

Thank you Dave, you were right on the money of course.   This round of
installations on my new computer just seemed to be a bit more difficult (or
I'm just a bit too confident and not diligent enough).

After I properly installed postgis support in mapserver I was having any
difficulties relating to user permissions.  I always forget that the web
server user has to exist and have permission to select from these tables.
In case someone has made it this far and is getting frustrated.  Remember,
you need to create a database user for your web server and mapserver to
use.  I.e. I used
>createuser apache
Then in psql you need grant them priviledges to access the data in your
postgis tables.
>psql mydb
>>grant select on mypostgistable to apache

I'm not sure if you have to or not, but I also did the following grants
too:
>>grant select on geometry_columns to apache
>>grant select on spatial_ref_sys to apache

This happens when you havent compiled mapserver without postgis
support.  You have to explictly
tell mapserver to add in support.

When you "./configure", you should do it like:

./configure  --with-postgis=/usr/bin/pg_config

Your pg_config program maybe in a different location.  pg_config tells
mapserver where the postgresql include and lib directories are.

You should check your configure log and see if you specified where
pg_config is correctly and that configure found it sucessfully.

Subject: [mapserver-users] Projection question - Australia
Message-ID: <00a001c1e0b2$71925320$2a42a8c0@marie>

Hi all,

I have a question about projection.  My map data of the NSW area of Australia uses WGS84 datum and spheroid.  Units are in geographic Digital Degrees.  This looks fine when displayed in mapserver.

I also have a flat file of x,y co-ordinates from the AMG zone 55 which I want to overlay on the map.  I have managed to figure out how to generate a shape file for this.  But I am now left with the question of how to convert from AMG cartesian co-ords to WGS longitude and latitude.  I think it may be possible to convert these using PROJ4 before I create the shape file, but I am not sure if it's possible to convert from AMG to WGS.

I will continue to search for PROJ4 examples to see if this is possible but in the meantime if anyone could advise I would be most grateful.  I am not a cartographer so excuse any obvious ignorance in the wording of my question!

Regards,

Marie

The person who posted the message you refer to does have a version of
the
mapplet that supports PNG. He had to use a 3rd party class library for
PNG
support. I believe he will provide the code (I don't have it here).
Your other
option would be to require users to use a new version of Java. I
believe the
most recent versions support PNG natively. Of course that will require
the
use of a plugin on the client side.

Steve,

I was looking at your mapplet code and found it does not support PNGs.
Neither does DM Soln's Rosa applet.

Searching through the list archives, I found the following message from
July
2001.

==========
I have a version of Steve's mapplet that does support PNG.  Currently,
I'm
working finding a preprocessor that will help make the PNG mapplet
code
available to everyone.

If you would like, I could forward to you the PNG libraries and
mapplet
source code.  All you would need to do is compile the source and put
all the
class files in a web accessible directory.

could you, or someone else, shed more light on this? Is there a version
of
either of these Java applets that does work with PNGs? if not, what
would it
take to compile that support in?

Many thanks,

Hi There,

We have used the same 3rd party library to add support to PNG in the Rosa
applet. You can download it at :

 http://www2.dmsolutions.ca/webtools/rosa/rosa_downloads.html

 PS : download the developpment version.

Later,

Hi Folks: I'm looking for a global (or just north and south america)
raster dataset to add context for a visualization I'm working on. This
layer would be draped over a DEM to add context. Something like veg.
cover, land use or an AVHRR mosaic would be great. Needs to be fairly hi

Subject: [mapserver-users] Shapefile indices and Mapserv vs Mapscript
Message-ID: <3CB48ACA.1030500@i3.com>

Greetings,

I'm finding a quirk between mapserv and mapscript and
am hoping that someone can enlighten me.

Using mapserver and mapscript 3.5 I am finding that
mapscript cannot access a shapefile without the
presence of a shptree index, while mapserv can
access the same shapefile without a shptree index,
even when using the same map (produced from map.save()).

Why would mapscript produce a msSearchDiskTree() error
when there is no error from mapserv?  Do mapserv.exe
and mapserver.lib not use the same code to access
shapefiles?

I'm using mapserver and mapscript that I've built on
Win2k from the 3.5 source.  Am setting the shapefile
layer to connection type MS_SHAPEFILE.

thanks,
Sean

Sean,

The msSearchDiskTree() error is only informational. It means that some
of your shapefiles do not have spatial indexes built for them (ie: not
all *.shp have a *.qix file. You can suppress the message in mapscript
by putting an '@' in front of the call to draw the map, or build the
indexes using shptree. Mapserver has probably been built with ignore
missing data option so it ignores this fact. the error report by
mapscript is from the mapscript wrapper and not mapserver. So that
should explain the difference. I have written a bug/enhance request to
include the file name that is generating the error to make it easier to
chase these down.

I have an web application using MapServer version 3.11.

 Example 3 for itemquery in MapServer test suite uses version 3.11.
 I've modified the map file by removing QUERY and moving template

Hi Folks: I'm looking for a global (or just north and south america)
raster dataset to add context for a visualization I'm working on. This
layer would be draped over a DEM to add context. Something like veg.
cover, land use or an AVHRR mosaic would be great. Needs to be fairly hi
rez (2 minute+). Any one run into such a beast? Thanks in advance!

Lawrence,

I just went through this same issue upgrading one of my applications to
version 3.5.

You need to add in the &qlayer=layername&map_layername_filter=itemname
=,>,<,etc. value in the URL

Also make sure you have the filteritem defined in the layer you are
querying.

Also see message:
http://mapserver.gis.umn.edu/wilma/mapserver-users/0202/msg00184.html

Hope this helps,
Brian

I have an web application using MapServer version 3.11.
I've tryed to upgrade to MapServer 3.5 but itemquery does not work 
at all.
 Example 3 for itemquery in MapServer test suite uses version 3.11.
 I've modified the map file by removing QUERY and moving template 
in CLASS body.
Following message appears: "msQueryByAttributes(): Query error. 
Requested layer has no filter defined. "
Could anyone make

Marie,

I would say that the AMG Zone 55 you refer to is equivalent to UTM Zone
55, so the various desktop packages should provide that translation. 
ArcView and ArcTOOLBOX do.  There are other point by point conversion
tools around.  Note the new GDA94 is close enough to WGS84 with a
vertical translation.

Subject: [mapserver-users] Projection question - Australia
Message-ID: <C1324DB9FA4AD31190D500902786B5E6016A155B@xchange.ffp.csiro.au>

My take on this:

AMG55 == UTM zone 55 projection on the AGD66 datum. 
(AMG meaning Australian Map Grid, AGD Australian Geodetic Datum). 

MGA55 == UTM zone 55 projection on the GDA94 datum. 
(MGA meaning Map Grid of Australia, GDA Geocentric Datum of Australia). 

GDA94 and WGS84 are apparently the same for most purposes.  

Note that if the flat file is correctly described, AMG must mean 
AGD66 datum.  

Anyway, to answer your question I think you need to use the Projection 
Utility that comes with Arcview 3.2 (NOT the 'projector' extension, 
Projection Utility is a standalone program).  This will do the 
datum conversion for you.  If you don't have Arcview there are other 
programs that will do it for you, I'm not familiar with PROJ4 but 
would be suprised if it can't do this.

Yes, this is the best 'free' whole earth image I know of :-)

Message-ID: <JMLTQ41B7FEFBFBIEHFBPLOMNLF0B8.3cb52aa1@rogers>

Hi all,

I am now trying to add a point and data to an existing shapefile.

The archives suggest this can be achieved using perl or php using the shapeobj

I am getting the point location and data from an ActiveX control, not from the browser itself.
I can probably raise an event that will allow me to interact with MapServer as I have done
to produce a querymap using CGI calls, but am unsure of how to deal with it.  (very new at this whole
browser Active X thing).

The CGI mapscript does not have the shapeobj as a class, so what are my options to achive this? 

Is there a way of interacting with Mapserver that I am missing?

Message-ID: <3CB55752.A4323AF@nauta.it>

I used mapserver & mapscript without proj support and it was perfect!
Now i'm tring to add proj: I installed debian proj package (v 4.4.5)
and compiled mapserver with:

  ./configure --with-postgis=/usr/lib/postgresql/bin/pg_config
	--with-tiff --with-jpeg --with-freetype  --with-png 
	--with-gd=static,/home/giorgio/work/map/gd-1.8.4/ --with-proj

everything seems ok but ... when I try to see itasca demo in the
browser, i can see the first map but if i try to zoom or pan then the
script dies with no output at all.
No trace in apache error log, (only a "Premature end of script headers")
I also log error (with SetEnv MS_ERRORFILE /var/tmp/map_error.log) but
there is no output there!

What can i do to find out the problem?

This is my mapserv -v
MapServer version 3.5 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP
SUPPORTS=PROJ SUPPORTS=TTF SUPPORTS=WMS_SERVER INPUT=TIFF INPUT=EPPL7
INPUT=JPEG INPUT=POSTGIS INPUT=SHAPEFILE

thank in advance ...

Ok, thanks to Brian Fischer <bfischer at mpls.houstoneng.com> 
for advice regarding itemquery. Finally I've found query examples for 3.5 version at http://maps.dnr.state.mn.us/mapserver_demos/tests3.5/itemquery/test.html
and all goes ok for polygon features. I have trouble zooming to a point feature instead 
a polygon feature. I need to make the same query like in example 1 using points features instead polygons.

using: 
src="/cgi-bin/mapserv?map=[map]&codent=1000&mode=itemquerymap&mapext=shapes&qlayer=[qlayer]" height="300" width="300"

in my template, works for polygons 

I've tryed this for point features in my template:

src="/cgi-bin/mapserv?map=[map]&codent=1000&mode=itemquerymap&mapext=shapes&qlayer=[qlayer]&scale=5000&mapxy=[shpmid]" height="300" width="300"
and doesn't work

my map is:

I'm a new mapserver user, older user of postgres.

I think it's very usefull the possibility of using a key field different
from oid, normally a relational db programmer defines a "primary key"
for quite every table, and a primary key is for definition unique (not
integer ... ok). The most usefull think is that postgres automatically
creates an index over a primary key field so access is faster when
filtering over that field ( if you want index over oid you must create
it by yourself).

You create primary key simply writing

CREATE TABLE table_name (key integer PRIMARY KEY, other_field
text,other_field2 text);

So i would like to suggest the possibilty of using a primary key field
if it exists in the db (may be controlling wheter it is integer or not).
(From postgres 7.x oid column can be disabled so it's no more sure that
oid column exists!)

The simplest way is the one you suggested, that is let user specify
which column to use.
It's also possible to query system table to discover if our table has a
primary key but this is quite complicated expecially for views!

For normal table the following query return all integer attributes
(column name) that are primary keys (always returns 0 record for views):

select attname from pg_type,pg_index,pg_attribute,pg_class where
pg_type.oid = atttypid and indrelid=attrelid and indkey[0]=attnum and
indkey[1]=0 and indisunique and pg_class.oid = attrelid and attnum > 0
and typname in ('int2','int4','int8','integer') and
relname='table_name';

( indkey[1]=0 to discard multicolumn keys )

Obviously a column can be a "unique integer identifier" also if it's not
defined as a primary key in the db .. but only users nows it!

Finally the strategy for defining SRID coud be:
1) if user suggest the column use it
2) Otherwise look for an integer primary key, if found use it
3) Use oid (may be control if oid exist or raise an error!)

(select attname from pg_attribute,pg_class where pg_class.oid =
attrelid  and attname='oid' and relname='p'; return a record only if oid
exist)

An other suggestion: to get all field's names (and their types) of a
table you can use the following query:

select attname,typname from pg_class,pg_type,pg_attribute where
pg_class.oid = attrelid and  pg_type.oid = atttypid  and attnum > 0 and
relname='table_name';

more simple of "verbouse explain" and valid also for views ...

PS: can someone send me the path for using "USING UNIQUE ID urid"?
Thanks a lot!

I have yet presented this problem but nobody answered me, please:

say me if this is a too stupid question ...

I have a map (North Italy) and I'm trying to display it with Mapserver.
The map is displayed but only a "fragment" of the map appear on the screen.
If I want to see the remainder of the map I have to use the pan function.

How can I do in orther to view all the map?

This is my map file (a fragment):

NAME DEMO

SIZE 600 600
EXTENT 6.174567 42.975424 14.815678 47.143435

IMAGECOLOR 255 255 255
SYMBOLSET "/Program Files/Apache

FONTSET "/WINNT/Fonts/fonts.list"

If I try to modify the EXTENT nothing happen, another fragment of the map is
displayed (but not the entire map)

Somebody can help me? I hope so ......


Thanks,

have any comments on the future of this.  The reason I am asking is that we

Stefano,

I am not sure if this is the problem but you aspect ratio of image size
to map EXTENTS is not 1:1

image   dH=600 
        dW=600 
        ratio=600/600 = 1

extents dx=(14.82- 6.17)=8.65
        dy=(47.14-42.98)=4.84
        ratio=8.65/4.84=1.79 which != 1 above

so try:
EXTENTS 6.17 40.735 14.82 49.385

Hello, list.

I know this is not the place to put this question, so please forgive me. 
  (Besides I think I'm asking the obvious):

I've got a table in postgres with a field called 'arc' of type 'lseg'.
If I need to query for the start point, I call it this way:

SELECT arc[0] FROM entities;

If I need the end point, I use:

SELECT arc[1] FROM entities;

But if I need the x coordinate from the start point?
How do I query for it?

Thanks in advance,

Stefano,

You need to provide more info.  Are you displaying your layers in
lat/lon or is it being reprojected?  Are you using shapefiles or some
other vector format?  I'm asking these questions to establish a context
to your problem.  If you are using shapefiles, it could be that your
data has different "regions"...  if this is the case, I don't know how
to fix it other than running shapearc and regionpoly in arc/info before
exporting it as shapefile again.  Anyway, that's a wild guess but I've
seen it happen to a lot of people.

If it is projection issues, you'll need to tell us more about your
projection.

Ed McNierney, Stephen Woodbridge, Tyler Mitchell, etc..

Thank you very much for the responses below.  Our IT director and I went
'round and 'round with this thing.  We're using IIS and apparently there are
a few ways around this problem.  We made some changes that allowed me to use
a UNC format and map directly to other servers.  We lost a little speed but
avoided duplicating 55 GBs of ortho photos.  Folks may want to refer to
Microsoft knowledge base article Q207671 - Accessing Network Files from IIS
Applications. 

Thanks again,

Steve et a. -

That's not quite correct.  The Web server runs under a user security
context, like everything in Windows 2000.  If you're running a Web server
with a site that permits anonymous user access (as most do), your server
will have a LOCAL user account named IUSR_<machinename>; for example, if the
machine is named FOO, then there is a local user account named IUSR_FOO that
is used by the server for anonymous access.

That means that the MapServer CGI runs as if it were run by the logged-in
user IUSR_FOO, and it only has access to things that IUSR_FOO can access.
The default setup is for IUSR_FOO to be created as a local machine account,
NOT a domain account - it's an account that only exists on the Web server
machine.  As a result, since it's a local machine account, it has NO ACCESS
to network resources.  You have to be a domain user to get those.
Therefore, you won't be able to see any network data files.

You can change the Web server's user account to be a domain user account,
and then you can get access to domain resources.  Remember that this is a
two-edged sword.  The reason the default account is a local machine account
is to prevent security problems; the default setup only permits access to
the local machine, so the risk from a Web attack is minimized.  If you
change that account to a domain account you potentially expose your entire
domain to an attack.  There's nothing wrong with that; it just means you are
increasing the benefits and increasing the risk, and you need to manage the
security situation appropriately.

This could be because the web server process does not have access to the
network drives. This could be because of access rights, or it could be
because you are using a mapped drive which only exists for you as a user
after you log in. Since the web server does not log in it does not have
any mapped drives and can only access the local drives.

The problem probably is that the results of the [shpmid] replacement are
not being escaped properly. Without being escaped there will be a space
between the coordinate values which may bust certain browsers. You can
get an escaped version of most parameters by appending _esc to the end
of the term to be replaced. Try [shpmid_esc] and see if that helps.

Message-ID: <scb580ee.068@co5.dnr.state.mn.us>

The CGI (mapserv) program has no facilities for adding data to a
shapefile. It's a display/query tool only. You'll have to use mapscript
or some other tool to append/edit a shapefile. You can pass information
to a script in a similar manner as you've done with mapserv, but since
you have full reign on what that script does you can invent variables as
necessary to pass the data.

Hi all,

I am now trying to add a point and data to an existing shapefile.

The archives suggest this can be achieved using perl or php using the
shapeobj

I am getting the point location and data from an ActiveX control, not
from the browser itself.
I can probably raise an event that will allow me to interact with
MapServer as I have done
to produce a querymap using CGI calls, but am unsure of how to deal
with it.  (very new at this whole
browser Active X thing).

The CGI mapscript does not have the shapeobj as a class, so what are my
options to achive this? 

Is there a way of interacting with Mapserver that I am missing?

Thanks everyone for the replies so far.  I was very pleasantly surprised
that my question got answers so quickly!

I've managed to create a file (using Mapinfo) with the projection I want
i.e. MGA55 on the GDA94 datum.  But I need the units to be in lat and
longitude degrees - as opposed to x,y meters.

For example take a point

888070 6248580

I want this to be represented as

151.1925896 -33.83179046

I 've tried using PROJ4 to covert to degrees, but am not having any luck
(possibly because I don't really understand what I'm doing and the
documentation doesn't help me much).  This is my PROJ4 command ....

proj -v -I -f  "%d" +proj=utm +ellps=WGS84 +a=6378137 +rf=298.25
888070 6248580

I get ...

1080240235 1078729873

Can anyone advise or suggest an alternative approach?  Thanks a lot.

Marie

Stefano,

You might want to use shapechk.exe if you want to get the extents of a
shapefile.

Look for info at:
http://www.dnr.state.mn.us/mis/gis/tools/arcview/tipsheets/Tip5.html
And download shapechk.exe from:
http://www.geocities.com/SiliconValley/Haven/2295/howto_shapechk.html

Then take the 'biggest' shape file and get the EXTENT using shapechk.exe
and put those settings in your map-file.

Erwin

Subject: [mapserver-users] MAP EXTENT

I have yet presented this problem but nobody answered me, please:

say me if this is a too stupid question ...

I have a map (North Italy) and I'm trying to display it with Mapserver.
The map is displayed but only a "fragment" of the map appear on the
screen.
If I want to see the remainder of the map I have to use the pan
function.

How can I do in orther to view all the map?

This is my map file (a fragment):

NAME DEMO
STATUS ON
SIZE 600 600
EXTENT 6.174567 42.975424 14.815678 47.143435

UNITS DD

IMAGECOLOR 255 255 255
SYMBOLSET "/Program Files/Apache
Group/Apache/htdocs/Nord/symbols/symbol.sym"
FONTSET "/WINNT/Fonts/fonts.list"

If I try to modify the EXTENT nothing happen, another fragment of the
map is
displayed (but not the entire map)

Somebody can help me? I hope so ......


Thanks,

Stefano B.

Jaqueline,

You can simplify the problem because your javascript code is generating
a GET to send the form. So what you need to look at is:

1) What does the URL look like that the javascript is generating?
   It is to hard to figure that out by reading the javascript :)
2) What does you mapfile look like?
3) What version of Mapserver are you using?

If you post this information to the list, I'm sure someone can help
figure out the problem.

Hello 

I'm Sorry  by the annoyance, but we have a small problem executing an 
example of "itemquery" that is in the page of MapServer in the following 
direction:

http://maps.dnr.state.mn.us/mapserver_demos/tests/itemquery/

What we are trying to do is to view our layer with some areas
iluminated, 
but this areas depend on a query, and we are having troubles with it. 

We already modified the code with our own data, and 
when we execute this code, it shows the following error:

msQueryByAttributes(): Query error. Requested layer has no filter
defined. 

We have reviewed all the documentation and we have not been able to
solve 
the problem.

The code that we have is the following: (like test.html)

html>
<head>
  <title>MapServer Test Suite - ItemQuery</title>
  <script language="javascript"></script>
  <script language="javascript">
    var counties = new Array('Puebla','Mexico');

    function write_counties() {
      var i;

      for(i=0; i<counties.length; i++)
        document.write("<option> " + counties[i] + "\n");
    }

    function submit_case2() {
      var i, sep='';

      document.case2.map_county_filter.value = '/'; // start of a regex
      for(i=0; i<document.case2.name.length; i++) {
        if(document.case2.name.options[i].selected)
          document.case2.map_county_filter.value =
document.case2.map_county_filter.value + sep +
document.case2.name.options[i].text;
          sep = '|';
      }
      document.case2.map_county_filter.value += '/'; // end of a regex
    }
  </script>
</head>

<body bgcolor="#ffffff">

<input type="submit" value="Go!">

</form>


________________________________________________________________________
 
We do not understand where is happening with our filter, what are we 
doing wrong?


We have checked the template (the html file) and the map file, we
believe 
they are correct.

We'd like to know what are we doing wrong and where?

Could you help us?

Where we can find information or other examples about "itemquery" using 
"querybyfeatures"?


Thank you. =)

Message-ID: <scb5a3d9.031@co5.dnr.state.mn.us>

Will check on build issue. But regarding 'title' as a keyword. This is
on purpose. One of the problems that needs to be addressed is the unique
naming of classes. Since 'name' is used elsewhere in mapfiles for that
purpose it should probably be used in classes as well. That means we
need another attribute to handle a prettier class name for legending,
hence the keyword title. Naming classes allows us to add capability for
turning classes on/off, retrieving them by name in mapscript and bunch
of other things. At this point the title keyword has been reserved but
not implemented. Please update map files (just quote the word title)
accordingly.

Thanks to everyone who responded, I finally got it to work.  I didn't
have a setup.py in my MapServer distro, but I found one at
http://www.vso.cape.com/~nhv/files/python/mapscript/setup.py by
searching the list archives.  After modifying it for my setup, I was
still getting an error about a missing __init__.  In setup.py,
mapscript and mapscriptc are spelled using studly caps and that is
apparently what was causing the problem.  Substituting MapScript for
mapscript in setup.py fixed the problem, and the module is now
successfully imported.

Now if I can just figure out how to use it... :)

Thanks again,
Ben

Thanks to those who did reply and offer suggestions.

In the end I just put a javascript redirection in the query template.  This was simply a call to an asp page, but I was able to pass the ID of the object that was 
pointed to on the map.  This then allowed me to do database calls to extract data from SQLServer, etc.

The standard query template with scripting looks pretty good for most instances, but this was a good workaround in this case as I wanted to reteive data from a 
non-connected SQL database for the paddock that was pointed to.

In the process was also able to get CGI mapscript calls from an ActiveX control if anyone needs that useless bit of info.

When this job is over, I will be installing PostreSQL to try it out.

It is possible in the development version for 3.6. It now supports a
"TRANSPARENCY" parameter
(at the LAYER level) that takes an integer argument representing the %
of transparency to use.
100 is completely opaque, 50 is 50% transparent and so on. Color
limitations will definitely affect
the quality of the output. The samples I've seen are pretty good
though. For earlier versions you're
limited to hatched fills...

------------------------------------------------------------------------

The message is:
  msDrawRaster(): Image handling error. Unrecognized or unsupported image format

If I use only Mapserver WMS Servers, everything works fine...

If I include a "request=map" in the CONNECTION, I get a blank image at
scales where the rivers show up at cubewerx's client.

I must be missing something...

Has anyone out there using SDE used the "CAD client" feature of SDE to bring
in CAD data (dxf, dgn, or dwg) to MapServer? 

I *frequently* have the need to include such files in my apps, and am
looking for options (besides converting to shape).

Cheers!

Is anyone using MapServer with ERMappers IWS?  I see a MapServer demo on
their site about integrating MapServer with IWS, but I was wondering if
anyone can tell me how I could add a layer into my map file that would grab
an image from IWS (I assume using WMS).

I wonder if others could comment on the use a fill symbol that could have a
"transparent" component to it - i.e. a semi-solid shading rather than a
completely transparent fill like offset does?

Hi folks,

        I need to apply a polygon layer over a raster and/or DEM layer,
             the problem is the filled polygons cover the image, so it
turns
        to be useless. I guess i can use the 'pseudopolyline' feature
        (that is, ommiting the color sentence in the map file), but what
        i'd really like is to draw the polygons with transparence. Is it
        possible with the actual mapserver code?

thanks a lot,

David,

This bug was fixed after the 3.5 release, around the end of January, so
you need a DLL built after that date.  The following one should do:

Message-ID: <200204121858.g3CIwCQ23246@yogi.medinaco.net>

I think there are quite a few sites out there that use tiff's. If you end up needing a sample just ask, but I think your problem may be in the data somewhere. If you have ImageMagick available do 'display <tiff_file_name>' and then Miscellany->Image Info and look under the Image: portion for colors: if it is over 256 then do 'convert -colors 256 <in_tiff_file_name> <out_tiff_file_name>'.
We had a similar problem where our images where specified as 8-bit but were not classified down to 256 colors and the raster layer would not display. The best part about it was that we could not detect ANY visual difference between images but yet the reclassified image was 1/3 the size of the original (which was nice after starting out at 38GB).
Hope that helps.

Tyler,

We are currently implementing a IWS/ Mapserver app. 

But, the integration works the other way around to what you think I'm afraid.  IWS delivers the images as layers to the client and when vectors are also used, the vectors are also 
delivered by IWS as an image layer overlay to the client.  The image layers are handled by a client-side plugin.  On a change of extent, the plug-in triggers a request for new parts of 
the image that it doesn't already have and a new vector layer overlay.  The procedure is quite well explained in their docs, and even code for the integration of Mapserver.

Its disadvanage is its requirement for an 400K  ActiveX download or an plugin for Netscape, but if you have to deliver images, it has a lot of advantages.  For a start, an aerial photo / 
satellite base is only streamed down once, rather than for each separate request, and thus a change of extent or zoom means only a download of a small gif rather than a large jpg.  
Then it only requests the parts of the image that it doesn't have already, meaning that if you come back to a part of an image that you looked at before, it is already on the client 
machine.  Its also not freeware for reasonable sized installations.

One advantage with the download, is that if the client already has to download a plugin, then they may as well download a full client side app, and you can incorporate a lot of client 
side functionality that would be difficult otherwise.  IWS plan on releasing a java version of their plugin later this year that may change the options though.

Robert.

I'm writing a WMS 1.0.0 and 1.1.x interface to do this at the moment. It 
will provide a WMS interface to ECW data from Image Web Server and from 
local file. (Windows only at this stage.)

In the meantime, there are two possible approaches:

** Client Side **

The ECW viewer plug-in, in your browser, would request an image from 
MapServer and overlay it on the ECW raster data. All you need to do it 
write some Javascript and tell the plug-in which colour in the MapServer 
image to make transparent.

There are examples of this in the Image Web Server documentation, and you 
can view some working examples at www.earthetc.com.

I wrote a Javascript WMS 1.0.0 library to do this a while ago. If anyone is 
interested I'll see if I can dig it up.

** Server Side **

The usual approach is to run MapServer on Windows and compile it with ECW 
support. That lets you read ECW data from a local file. If you want to use 
Image Web Server (over HTTP) instead of a local ECW file you should be able 
to replace the ECW file path in the map file with an ecwp URL (I haven't 
actually tried this with MapServer but it works fine on my image server).

e.g. Replace "d:\ecwfiles\yourimage.ecw" with 
"ecwp://someserver/ecw/yourimage.ecw"

Note: As previously discussed on this list, MapServer's handling of 24bit 
colour still needs a bit of work so the quality of the output is not 
optimum when reading ECW data.

Some time passed ...
I've studied the matter a bit!

The error is generated when msSHPWhichShapes tries to look for an index
(.qix file) to retrieve shapes for layers ... I've no qix file so it is
right ... but it should be a "warning", On the contrary, when I call 

	$img=$map->draw()

then I found $mapscript::ms_error->{code} = 1 (Unable to access file)
so i cannot use it to understand if draw() was ok.

I didn't found written anywhere that we have to look ms_error after
calling draw method ... is it correct?
I tried to assume that all is ok if $img is defined but in some cases
that was wrong because also if $img was defined than system crashed when
i tried to save the img.

Joe -

I think the problem is in definig "heavy load tests".  I don't see any of the commercial Internet map server providers publishing detailed hardware requirements (although I may have missed something) because it's a very complicated question.  That's probably why there's a lack of replies.

Do you have a specific set of requirements in mind?  If so, let us know and we'll help.  Creating a document describing all possible hardware requirements for all possible sets of performance criteria is a massive task, and isn't likely to happen any time soon.

Joe,

I'm not sure if there is any definitive document, but here is some
information that you might find useful in sizing your own
implementation. If you haven't seen or used:

    http://www.joedog.org/

I would recommend getting it (its free) or something like it. I just did
some analysis on a site that will be migrated to a production server at
some point. Here is what I did and some of my insights. 

My goal was not to get optimum performance out of the box. It was to
prove the the mapserver configuration was as optimimal as I could make
it and to demonstrate that the mapserver times were consistanly in the
2-6 sec range and be able to explain why the large numbers where system
configuration issue and not mapserver issues.

I wanted to be able to know two things, mainly:
  1) what was user response times under load
  2) what was mapserver response times under load

These are both important and tell you different things. 
  1) talks more to the system configuration and tuning and 
  2) tells you how well you have mapserver configured.

How I did my testing using joedog: With joedog you create a file of urls
that you want multiple joedog "users" to lay seige on the server, so you
can tell it to attach the server with 5, 10, 100, whatever simulated
users. Each user grabs a random url from the file and hits the server
then sleep a specified amount of time and repeats until the end criteria
are met.

So I created urls, secifically picking locations that were in each of my
different shapefiles and at 3-5 different zoom scales. The idea being to
avoid all the users hitting the same location and getting the benefit of
the system cache a small number of files in its system cache.

I then ran the test with 1, 2, 3, 5, 10, 15, 20, ... users until a
swampped the system. I also ran some sample test running joedog on the
server and running it remote (from the US to Europe) to see if I was
getting internet lag in the results (if it was there it was not
measurable.

Oh, you need to run enough samples at each user count to get a good
average that is above the noise. You can test this by rerunning a sample
and seeing it the numbers change significantly.

Here is what I found out using a 1-GHz Athalon, 1GB mem, running RH 7.2:

1) it is critically important that EVERY *.shp in your configuration
have a corresponding *.qix file.

2) I was able to get mapserver response time to be consistantly in the
2-6 sec range if the system file cache was working for me. If not this
time could go as high 20 - 40 secs with an occasional 60 sec outlier
when the system was heavly swamped. This difference I attribute to how
well the urls are hitting the system cache and the fact that one CPU can
only process data as fast as one CPU can do it.

3) Summary of some of user response times from joedog:
                      run
    users   delay    length   response time
-------------------------------------------
1)   10      15s      15m       39.78 secs
2)   10       5s       5m       40.48 secs
3)    5       5s       5m       22.04 secs
4)    3       5s       5m       18.57 secs
5)    1       5s       5m       16.96 secs
6)    1       0s       5m        9.80 secs
7)    1       5s       5m       14.27 secs (repeat of 5)
8)    1       0s      30m       15.10 secs (repeat of 6 for 30m)

Remember my comment about getting a large enough sample size? compare 5
and 7, 6 and 8 above.

For all the horsepower of this system, I was not impressed by the
performance. In fact it seemed significantly slower than my 450 MHz
AMD-K2 box and compiling seemed to take longer (but I did not run any
comparision timing tests), but it may mean that whomever set it up, or
the out of the box setup was not aimed at a server.

If I were setting up a server it would definitely be multi-process
before any thing else. Fast disks come next, this mapserver had like 18
GB of data that it had to romp through for every image, so have
tileindexes and shptree indexes made a huge difference. A fast SCSI raid
array is expensive, but if you expect lots of hits you are going to need
it.

I'm not sure I have answered your question, but I hope I have given you
the tools or ideas so you can size your own config up and document your
server requires.

If you convert to 256 color, you arent allowing room for any other mapserver
layer colors.  I had to go down to 200 colors, to allow for layer color table
allocation.. and if you use antialiased fonts, that bitch eats up a few colors
too.  Just my 2 cents..

One trick we've tried is sorting the palette in the TIFFs so that the most frequent colors appear first in the palette. ERDAS Imagine was used but there must be other ways of doing this. The reason to do this stems from the way colors are allocated. Initially a pass is made through the map file and all defined colors are allocated in the map. Then colors are added as pixmap symbols are encountered and raster layers are processed. With raster layers the palette is stepped through initially and allocated in the output map. If there's no room some color matching algorithms are applied. It can make quite a difference if common colors are allocated first. If possible you should also remove colors from the palette that are not used.

Stephen,
Your explanation helped a lot, now I am able to get the correct georef.
coords. of my map when I click on the image in my browser.
However still I am not getting any query results, I use the func.
GMapDumpQueryResults() from gmap demo. The table appears with the result
fields I specify in my map file, but no results are shown.
In my GMapDumpQueryResults() I o/p some info:
            $oRes = $oLayer->getResult($iRes);
            echo "$oRes->tileindex $oRes->shapeindex";
            $oShape = $oLayer->getShape($oRes->tileindex,$oRes->shapeindex);
this gives me a tile index = -1 every time.
I don't have a tile index defined in my map file, and I don't think it is
necessary since it is not in the gmap demo map file.
What I do in short is as follows:
1. detect query mode
2. convert pixel position to georef. coords.
3. create point obj.:
      $oClickGeo = ms_newPointObj();
      $oClickGeo->setXY($nClickGeoX, $nClickGeoY);
4. queryByPoint:
      @$map->queryByPoint($oClickGeo, MS_SINGLE, -1);
5. dump results
      $gbShowQueryResults = TRUE;
      GMapDumpQueryResults();
Can anyone help me? Thanks,

joe,

performance can be a problem if you have a ton of concurrent users...
what we do for our applications is load balance tween 3-4 machines,
and our normal load is about about 25k-30k map images per day/per CPU
using resonably fast processors and fast/wide scsi and/or raid.  some
of machines are stronger than others, but the load balancing takes care
of the issue.  once you get above a certain threshold the machine response
lags pretty bad, so you need to be able to scale the machines as the
concurrent load increases.  that configuration uses the rack mounted Dell
machines (last years model) running RedHat linux which seemed to be
a pretty good bang for the buck, although you could probably get away
with a cheaper/faster configuration.  At the time we bought these
machines, state-of-the-art was still below the 1Ghz milestone, so things 
may have changed.  It keeps getting better...

I have also tested on a 8 processor SGI Challege XL (about 3-4 yrs old)
and that machine was doing about 125k-150k per day and pretty much consumed
the machine.  This config was not as flexiable or cost effective as the
cheap PCs.  I seem to recall the IO became saturated somewhere around 4 
processors... so if you go this route, you may have to design some kinda
redundant storage technique..  I never could get the level of performance
I expected from the big machine.

My recommendation to anyone building a large system is to use rack mounted
(pizza box) PCs w/fast scsi disk on linux (I am biased)... and to stay
away from the monolithic architecture.

Chris Stuber (mapsurfer)

Subject: [mapserver-users] WMS Client - access to non-Mapserver WMS Servers
References: <3CB70993.7F2670A0@ikf.nlh.no>
Message-ID: <3CBAB1E2.3282C76C@ikf.nlh.no>

It turned out that my problems were syntactical. I changed to the
following "minimal" CONNECTION:

"http://www.geographynetwork.com/servlet/com.esri.wms.Esrimap?ServiceName=ESRI_World&VERSION=1.0.0&REQUEST=map&Layers=Rivers&Format=png"

And that worked!

The "REQUEST=map" has to be present, "REQUEST" has to be uppercase
and "map" must be lowercase (this case requirement seems to come
from Mapserver).
"VERSION" must be either uppercase or lowercase (not mixedcase)
(this case requirement seems to come from Mapserver).
"LAYERS" can be any case ("Layers", "layers", ...), but the layer
names are case sensitive.
"FORMAT" can be any case (Format, format, ...), and so can the
format ("PNG", "png", "Png", ...). Mime types (e.g. "image/png")
can not be used.
Mapserver took care of SRS and the STYLES parameter was not
necessary.

A suggestion to the developers could be to modify the code to use
"request=map" (instead of "getmap"?) when the WMTVER/VERSION value
is 1.0.0.
WMS Client support could perhaps also be made easier for the users
by making mapserver translate from MIME types ("image/png") to the
1.0.0 types ("png"), and by relaxing the case requirements for
"VERSION" and "REQUEST" ?

I hope my experiences can be useful to other users :-)

A landsat example was in the old mapserver demo set for version 3.3.

A copy of it is part of a rpm-package under 
 ftp://ftp.linux-magazin.de/pub/GIS/mapserver-3.3.011-1.i586.rpm
This out-dated out-of-the-box packages for Mapserver was part 
of an article I wrote for the German LinuxMagazin
 http://www.linux-community.de/Neues/story?storyid=135

Maybe it helps, please note that the old demo will not work with recent
versions of mapserver since the mapfile syntax has changed slightly.

Regards,

        Frank

Andrew,

Unfortunately, it does not currently appear to be possible to utilize the
OFFSITE capability with RGB (24bit) GDAL images in MapServer.  However, the
GDAL code does support alpha bands, so if you can produce PNG or TIFF files
with an Alpha layer, and set the alpha to 0 for areas you want to be
transparent, and if you ensure the files are treated by GDAL (not the builtin
PNG or TIFF drivers) then you can get transparency.

Of course, if you are bold you can easily hack the inner RGB loop to do what
you want in drawGDAL() in mapraster.c.

Best regards,

Message-ID: <18E0CC75605BD411907800508B8BB8D049E542@odin.enator.dk>


I've taken a tab-file from MapInfo, saved it as a shp-file, and put it into
MapServer.

In MapInfo the map is square but when displaying the same map in MapServer
the map is rectangle. The height of the map has halfed. Why is that?

It seems that different companies have different idears as to how to display
GIS data. I tried Geographic Explorer from Blue Marble Software (freeware),
and it showed the map like MapServer do. Actually, I can only get MapInfo to
show the map square.

My customer has gotten used to the way MapInfo shows the map. Can I make
MapServer show the map the same way?

You can see the two different maps here:
http://www.dynameks.com/cwu-btp/mapserv
Image 1 is from MapInfo and Image 2 is from MapServer.

Subject: [mapserver-users] itemquerymap attributes 
Message-ID: <20020416103448.19047.qmail@web9901.mail.yahoo.com>


Hello everybody!!!
I have finally solved the problem "zooming to a point feature in itemquerymap".
If anybody want help for the problem above just send me an e-mail.

And now my problem:

Does anybody know how to obtain [mapext], [imgxy]and[imgbox] values for an itemquerymap?

Actually  [mapext] is the most important.

Thank you, 

Lawrence

Ma, 

I use the default projection in MapInfo (or maybe the projection, the map
was created with). There is perhaps 50 different projections to choose from
in my MapInfo, but neither one seems to change the projection like described
below.

Anyway, I wanted MapServer to show the map like MapInfo do - not the other
way 'round. Do you know a projection to specify in the map-file that can do
the trick?

PS: I come from the database world - not the spatial world. Bare with me...

It appears that prepareImage now creates an imageObj (as do all the draw
methods) as opposed to a gdImagePtr. Try the following change to your
code:
$img->saveImage('/tmp/example.gif', $mapscript::MS_GIF,
$map->{transparent}, $map->{interlace}, 0);

If you happened to compile mapserver using --with-ogr you can use the OGR
libraries to access the TAB file directly which should point to out any
errors in the coversion to shape.

It looks like MapInfo stretches the data to fit a square view...  at
least from the way the images look.  Of course, I'm assuming geographic
projection. :)  Do you happen to know what the default projection in
MapInfo is?  Perhaps you can reproject it to something like Lambert
Azimuthal Equal-Area, with a central meridian that crosses Scotland and
Denmark (?) and a reference latitude that passes between Iceland and
Ireland.  I'm guessing somewhere between -11 and -12 for the meridian
and 56 and 57 for latitude.

If you reproject, remember to give your map extent in meters.

Good luck!

I've taken a tab-file from MapInfo, saved it as a shp-file, and put it
into
MapServer.

In MapInfo the map is square but when displaying the same map in
MapServer
the map is rectangle. The height of the map has halfed. Why is that?

It seems that different companies have different idears as to how to
display
GIS data. I tried Geographic Explorer from Blue Marble Software
(freeware),
and it showed the map like MapServer do. Actually, I can only get
MapInfo to
show the map square.

My customer has gotten used to the way MapInfo shows the map. Can I make
MapServer show the map the same way?

You can see the two different maps here:
http://www.dynameks.com/cwu-btp/mapserv
Image 1 is from MapInfo and Image 2 is from MapServer.

(I'm very impressed with all the good advise to my problem - thanks guys!)

Pericles,
I will try the below. But I'm more interested in getting the same view as
MapInfo into MapServer. Everybody I talk to seems to think that MapInfo's
(stretched) version looks more accurate - including my customer. Hmmm....

Thank you - this works!

Now there are two more questions arising:

* is msFreeImage obsolete now? 
  This is more or less a question for any kind of documentation for
  the version 3.6... 

* is there any mailinglist/webpage informing about upcoming changes (I
  think Frank Warmerdam asked a question like this some time ago)

1) I believe so. It has been replaced by $img->free().

2) I will attempt to integrate the changes into the documentation
(perl mapscript) as I
become aware of them. At this point the documentation is for 3.5 and there
will be a rewrite for 3.7(?) but 3.6 being development and changing
rapidly you may need to ask for now and someone should track down
the answer.

The range is 0-90 (degrees). 
The projection must be "longitude/latitude" as far as I can tell in MapInfo.

Message-ID: <CF5C7B60732AD211801900805F31912F024F2E69@WCMAIL>

HI,

I've been checking query/filter listings and have not found a snippit that
does what I want.  I'm using ms 3.5 in basic cgi.  I need help with:

1.	I want to use a itemtype text prompt to have a user enter a parcel
id number from my webpage.html. Everything I find seems to be derived from a
select list.
2.	Select the parcel from the parcel layer .dbf attribute table.  Need
syntax for the webpage.map file.
3.	Zoom to that parcel and outline or shade it with a contrasting color
from the normal parcel layer in the normal webpage map display area.

Thanks in advance.

Subject: [mapserver-users] Process Monitoring
Message-ID: <005c01c1e54f$59f21920$0300a8c0@p200>

Good morning:

I run Red Hat Linux and Mapserver 3.5, I was wondering if any of you could point me to some free server monitoring software (PERL, C, C++).  I run the UNIX command `top` every now and again to see how long my processes take and how much memory, but I'm looking for something automated and configurable-not me sitting and watching processes float to the top of the process control manager.

Basically I want to make a process that continually monitors the web related processes (maybe by username or command), printing a process log similar to the apache logs.  This process-watcher might kill process that use to much memory, then write the process information to a log so that I could review the culprit processes and how they were instantiated.  The more I think about this email, its probably already a module for Apache--any feedback would be appreciated.

I know this a mapping community, I apologize to anyone who disagrees with the context, but I know we are all concerned about web server performance.

Thank you for your time.

Subject: [mapserver-users] PERL MINSCALE MAXSCALE display control
Message-ID: <20020416142516.GA10432@extempore.otsys.com>

Is there anything about data which could override decalred MINSCALE and
MAXSCALE?  I have road data for Los Angeles County and the four
surrounding counties.  I declare the layer in my map file and set the
scale range to cover every zoom level I am using and I observe an odd
behavior.  The default map does not show me the roads in LA, but the
surrounding counties display correctly.  When I zoom out all the data is
painted.  At any zoom level out away from that point I can observe the
road network.  If I try to zoom in the LA roads do not get painted.

What are the right questions to ask debugging this?  I have verified
that the MAP, LAYER and CLASS definitions are correct in my map file by
replacing the DATA value with other randomly selected data sets which do
not demonstrate this behavior.  Any insight would be helpful.

Cordially,

Joe Bussell

Joe this sounds like you might have one of the following problems:

1) your tileindex is not right
2) the extents on your shp file are wrong
3) your shp file units or mapfile units or projection are not all
compatible
4) you have an out of data *.qix file

Try setting up a test mapfile with mimimal data to make it easier to
diagnose the problem.

Hope this helps,
  -Steve

HI,

I've been checking query/filter listings and have not found a snippit that
does what I want.  I'm using ms 3.5 in basic cgi.  I need help with:

1.	I want to use a itemtype text prompt to have a user enter a parcel
id number from my webpage.html. Everything I find seems to be derived from a
select list.
2.	Select the parcel from the parcel layer .dbf attribute table.  Need
syntax for the webpage.map file.
3.	Zoom to that parcel and outline or shade it with a contrasting color
from the normal parcel layer in the normal webpage map display area.

Thanks in advance.

Joe, Steve,

Also note that there was a bug in the 3.5 release of MapServer (that was
there since the beginning of times) which caused this type of problem
with some .qix files.  This has been fixed a little while ago and the
fix is present in the current CVS version.

Try deleting your .qix file if you have one, and if the problem goes
away then you have run into this bug.  You'll have to get a recent
3.6-dev build in which this is fixed.

Daniel

If you're just retrieving the map there's no way to get at the extent coordinates too. I've tinkered with encoding them in image headers, but that doesn't help all that much. Other work arounds would depend on what you're actually trying to do in your application.

Hello everybody!!!
I have finally solved the problem "zooming to a point feature in itemquerymap".
If anybody want help for the problem above just send me an e-mail.

And now my problem:

Does anybody know how to obtain [mapext], [imgxy]and[imgbox] values for an itemquerymap?

Actually  [mapext] is the most important.

Thank you,

Adam, 
I had a similar dilema.  The problem a I saw it was there was a limited amount you could do on the template in terms of server side processing.
I ended up doing this by putting a redirection to an asp page on the template, and getting data from a database using server side scripting.  

In this way I was able to pass a value of the ID for an object selected from the map to that page and do what I wanted with it.  The template code for the 
body is provided blelow, and you do not need to specify a web header, footer or template header in the map file.  In this example, the PadID is replaced by 
mapserver to be the value of C_LINKCODE found for the object in the search, and a second parameter is also passed for query type.

Once on an asp page, you can access databases using standard asp scripting if your on a windows server.  Others may be able to tell you options on unix 
etc. using other scripting languages that can call databases.

Good Luck
Rob

Template code follows.

Frank,
I am also wanting to do the same thing:
- i've erdas img. files, I want to set to x'parent the black sides of the
image
doing OFFSITE 0 doesn't work in the layer object.
>From your email I understand that to set x'parency options on 24bit images
you must have tiffs/pngs that too which have alpha channels, right?
I have erdas .img files and need to choose from the various bands which 3
to load (this has been done by using modified code of mapserver from
stepan kapka).
This means I've to do a "hack" in mapraster.c as you suggest?
Thanks.

Oh, seems to be a very bad issue!!!
I need to locate a point using itemquerymap (does anybody know another method?).
Then I need to pan around this location. This is a basic functionality for any GIS-like application.
According to this, I need to obtain the selected point coordinates (at least), or,
 for more than one selected point ,the extent or extent center of all selected features.
If anybody knows how to obtain the coordinates of a selected feature or other information 
how to obtain this, please let me know.

Thank you,

Lawrence

I am having problem with itemquery using dynamic expressions (from Mr.Steve Lime) in html form.
The problems are:
- the attribute QUERYMAP (in map file) have no influence, why? .So the result image just display an area/region 
  that was selected/queried and others region not shown. But I want to use QUERYMAP to display the  result of
  query in html template with hilite color.  
- the result of query (a field from dbf file)  not shown, noquery result.

here is my map fie:
NAME DEMO

#world94
EXTENT -194.32 120.82 194.32 -120.47

  TEMPLATE world.html
  IMAGEPATH "/var/www/html/tmp/"
  IMAGEURL "/tmp/"
END

QUERYMAP    #No influence ,why ?
SIZE 200 200
STATUS ON

STYLE HILITE
END

LEGEND
  KEYSIZE 18 12

  END

  DATA world94
    CLASS
    OUTLINECOLOR 250 0 0
    END
  TEMPLATE "world.html"
END
END # LAYER world94
END # Map File

Here is my form:

<form method=GET action="/cgi-bin/mapserv" >
<input type="hidden" name="map" value="/var/www/html/ms_demo/baleendah/world2.map">
PICK A COUNTRY:<BR>
<SELECT name="map_world94_class_expression" SINGLE>
<option value="('[ABBREVNAME]' eq 'Vietnam' )"> Vietnam</option>

<option value="('[ABBREVNAME]' eq 'China')"> Cina</option>
<option value="('[ABBREVNAME]' eq 'US')">USA</option>
</SELECT>
<input type="submit" value="GO!">
</form

HERE is my template result:

<TABLE BORDER=1>
<tr>
Version :[version]
</tr>
<tr><td>COUNTRY</td><td>AREA</td><td>LIFE EXPECTATION</td></tr><BR>
<tr><td>[ABBREVNAME] </td><td>[AREA]</td><TD>[LIFE_EXP]</TD></tr>
<tr><td><img border="2" src="[img]"></td></tr>
</TABLE>

Maybe some one can find what wrong with this?
Would you give me a simple axample of html form/map file for 'itemquery' please,please !

Message-ID: <200204170901.g3H91vP0002599@geomatica.ing.unico.it>

Dear List,

   I'm working with MapServer 3.5.1 (downloaded with Windows32 binary), 
   PostgreSQL 7.1.1 and PostGIS 0.6.2.
   I have problems for implementing multiple queries (CGI mode:
   "FEATUREQUERY" or "ITEMNQUERY") because I can't modify the filter SQL
   string via a form or a URL. After the selection of a new map file FILTER
   parameter, the PostGIS connection doesn't open the database and the error
   message appearing is

   	msPOSTGISLayerWhichShapes(): Query error. prep_DB:Error executing POSTGIS	
        DECLARE statement (0.6 failed - retried 0.5 and it failed too).

   I've tried also to build multiple queries using the CLASSITEM and
   EXPRESSION map file parameters and changing them via form. I've seen
   that it's possible to do it, but in this way you can't use complex SQL
   strings available in case of the filter change.

       How can I make multiple query with the possibility of selecting item

I think most people do this using mapscript.

Anders,

There is a SIZE and a UNITS as two separate items in the map file but I
am not aware of a SIZEUNITS item. Please check your map file reference
again. What section are you trying to use this in?

I have developed a MapServer application where the North Italy Map is
displayed. My problem is the following: in the map file I have written the following code: 
NAME DEMO
STATUS ON
SIZE 600 600
EXTENT 6.174567 42.975424 14.815678 47.143435 
UNITS DD
SHAPEPATH "data"
IMAGECOLOR 255 255 255
SYMBOLSET /Inetpub/wwwroot/Nord/symbols/symbol.sym
FONTSET /WINNT/Fonts/fonts.list
....
....
.... but the Italy Map doesn't appear entirely (only a piece) and if I try to
increase the DD interval MapServer show me the same piece of map. Why? Thanks in advance. ---

Good morning,
maybe the problem is that the SIZE image is a square (600 x 600 pixels), the EXTENTisn't (8,641111 x 4,168011 DD). You can try to change the SIZE according the EXTENTION dimensions.

The problem was that I was using sizeunits on the class object.... 
The layer in the mapfile should've looked like this:

layer
  NAME "Search_areas"
  TYPE Point
  STATUS on
  connectiontype ogr
  connection "data/tab/Radier.TAB"
  classitem "Op"
  SIZEUNITS meters
  class
    EXPRESSION "80"
    SYMBOL "circle"
    SIZE 160
    color 255 0 0
  end
end

Thanks

I'm not sure that everything on your list can be done without the use of Mapscript. However if you decide to check into Mapscript there should be quite a bit of discussion on those subjects.

Hello list,

I'd like to know if anyone can share some wisdom with me.

I typically would make a map of a polygon and a point, using a decimal
degrees. I'd like to now look at the resulting gif image from a pixel
perspective and, knowing the latitude and longitude of the point I
originally made, again find that point by referencing its location by
the number of pixels right and down of the top-left pixel in the image
(or whatever other referencing means is appropriate).

Any guidance appreciated.

Thanks,
Kieran

John,

can you post the section of your map file that controls the shapefiles
in question. Typically, it is the SIZE parameter often used in
conjunction with SYMBOL 'circle'

Dear List,

   I'm working with MapServer 3.5.1 (downloaded with Windows32 binary), 
   PostgreSQL 7.1.1 and PostGIS 0.6.2.
   I have problems for implementing multiple queries (CGI mode:
   "FEATUREQUERY" or "ITEMNQUERY") because I can't modify the filter SQL
   string via a form or a URL. After the selection of a new map file FILTER
   parameter, the PostGIS connection doesn't open the database and the error
   message appearing is

   	msPOSTGISLayerWhichShapes(): Query error. prep_DB:Error executing
POSTGIS	
        DECLARE statement (0.6 failed - retried 0.5 and it failed too).

   I've tried also to build multiple queries using the CLASSITEM and
   EXPRESSION map file parameters and changing them via form. I've seen
   that it's possible to do it, but in this way you can't use complex SQL
   strings available in case of the filter change.

       How can I make multiple query with the possibility of selecting item
   and value to be searched by the user?
       In other words, can I create queries using an association
   item-value like it was possible with MapServer 3.3?

   Thank you

   Best regards

Anders,

Well, I learn something new every day. :) I had not noticed SIZEUNITS in
my work with mapserver and the way you are trying to use it is very
interesting. I'll have to try that also.

I don't see anything obviously wrong with your LAYER definition,
hopefully someone else can help you.

Best regards,

You should be able to find it by simple ratios. Your map EXTENTS are
minx miny maxx maxy so your width = maxx - minx; height = maxy -miny;
your image is SIZE ix iy so:

px = (long - minx) / width  * ix
py = (lat  - miny) / height * iy

Should do it. You might need to deal with the fact that LAT increase
moving up the map and pixel address  increases moving down the map.

Subject: [mapserver-users] PHP/Mapscript project shapefile
Message-ID: <3CBD8DAB.7E3D513D@geoarctic.com>

Hi All,

Is this close to being the right method in projecting the entire
shapefile using PHP/Mapscript?

function projectShapefile()
{
 $projInObj = ms_newprojectionobj("proj=latlong,ellps=GRS80");
 $projOutObj =
ms_newprojectionobj("proj=stere,lat_0=46.500000000,lon_0=-66.500000000,k=0.999912,x_0=2500000.000,y_0=7500000.000,ellps=GRS80,towgs84=0,0,0,0,0,0,0,units=m,no_defs");

//re-write the existing file?
$shpfileObj =
ms_newShapefileObj("E:/software/apache/htdocs/tmp/to_stere/nb_rivers2",
MS_SHP_ARC);
 $shpfileObj = $shpfileObj->project($projInObj, $projOutObj);

}

Thanks in advance,

Mark

Hi Dan,

I need to back up a bit, and ask what the current status of Java MapScript
is?  I know that Steve has been working on it, and I would like to use it
for a class project with some classmates.  The instructor is using JSP,
beans, and lots of other java stuff, not PHP :(   

Here is the deal that I will offer:  There is a team of five of us that need
to get a simple project done for class.  We would use Java Mapscript to do
this, and document the heck out of it, and contribute this doc back to the
project.  What we need now is some guidance on the status of Java Mapscript,
the limitations, etc, as well as any general guidance for how to proceed.

Thoughts?

Hi Greg, The Java version compiles clean and I know some folks are having a bit of luck with it. I myself am struggling with installation issues but should over come those soon. Most issues will be related to the "maturity" of SWIG java module. Version 1.3.11 produces seemingly working code although that remains to be seen since not many folks have used it. The other gotchas will revolve around threading issues. Many of these have already been addressed when enabling --with-threads (or whatever it's called) when building the source, however, I'm sure there are other hurdles to be overcome. I'd certainly appreciate the feedback and documentation but you need to be aware that this is really an alpha version.

Subject: [mapserver-users] zoom in problem, PHP, winnt
Message-ID: <scbd61f9.057@em.agr.ca>

Hi,
 I have been starting to use php/mapscript and have had some success although right now I have a frustrating problem with the following code.  I took the php/mapscript example that uses a map of Europe and I substituted my own map of Canada, in decimal degrees.  The pan and zoom out work fine, but the zoom in results in my browser just sitting there spinning its wheels.  In my map file, the extent is set to: EXTENT -145.0 40.0 -50.0 85.0 and SIZE is set to 600 284.

Can anyone see what is wrong that would cause zoom in to fail?  I get no error messages, and eventually PHP responds with a time out message.

Below is my code.

Thanks,
D. Pagurek

This can happen if you use EPSG projection codes (e.g. init=epsg:4326)
but the file "epsg" is missing in the proj directory
(/usr/local/share/proj/epsg on Unix), or if you try to use an epsg:XXXX
code that doesn't exist in that file.

You may want to upgrade to the latest version of PROJ.4 on the machine
that gives this error (the latest PROJ should include the 'epsg' file). 
Or you can download a copy of the epsg file from 
http://www2.dmsolutions.ca/mapserver/dl/proj4-epsg.zip

If your server runs on Windows, then the epsg file is searched in either
C:\PROJ, or C:\PROJ\NAD depending on the version of PROJ that was used
to compile MapServer.

It shouldn't have worked in 3.5. Projections are not simple structures and really shouldn't be mucked with. So in 3.6 direct access to that was blocked and getProjection and setProjection methods were added to mapObj and layerObj. The methods take/return PROJ.4 projection definition strings.

It appears member projection is gone, try:
my $project = $map->getProjection();

That should return the character string of parameters directly. Whereas before it should have been similiar to:
my $project = $map->{projection};
my $projstring = $project->{args};

Hi There,

 I just tested your code (using my own map file) and things seems to be working properly whne zooming in. So there seems to be no problem with the code here.
 I am assuming it might be related to your map file, so If you send me your map file and some sample data, I can do a test and let you know how it goes.

Best Regards

Hi Steve,

I am not using the latest of everything, but I have compiled sometimes 
back and am still using it. Dan wanted help in Windows which I don't 
have access to. Under Linux, it compiles without any problem except on 
Stable mapserver 3.5 & SWIG 1.3.11, I changed the java files little bit. 
But, when I did it check the nightly build a while back it compiled 
clean and working wonderful. I am using Java mapscript on Linux for a 
while now and didn't have any problem. I can help anyone on this, if 
they are on Linux.

Most issues will be related to the "maturity" of SWIG java module. Version 1.3.11 produces seemingly working code although that remains to be seen since not many folks have used it. The other gotchas will revolve around threading issues. Many of these have already been addressed when enabling --with-threads (or whatever it's called) when building the source, however, I'm sure there are other hurdles to be overcome. I'd certainly appreciate the feedback and documentation but you need to be aware that this is really an alpha version.

Jeff,

We ran into this ourselves a few minutes ago, it's a result of a recent
change.  We're looking into it and will let you know once it's fixed.

I have a polygon layer that I've classified using CLASSITEM and a set of
CLASS objects.  I also want to display labels for each polygon.  Do I need
to use a separate LABEL within each class object (I know this will work), or
is it possible to apply a single class object to label all polygons (I'm
having trouble getting this to work)?  I can successfully use an expression
to label all polygons from one class object, but if I put that class object
before the rest of the class objects, it disables the color rendering of
those polygons.  If I put it at the end of the other class objects, the
labels are hidden beneath the rendered colors.

Thanks,
Dylan

Dylan,

You need to use a separate LABEL in every CLASS. Here is why ...

I think CLASS works like a SWITCH or CASE in that as soon a one class
section is executed no more are looked at. So if you put your label at
the bottom only the polygons that are not colored are labeled and if you
put it at the top the they are all labeles but not colored. You will
have to put the label block in every class section if you want them
colored and labeled.

Hi,
one question: why, after the assignment $scale = -1 ?
I'd like to use $scale in order to display a map only for a particular scale
range but its value is always -1.


$gpoMap = ms_newMapObj("mymapfile.map");
:

:
$poLayer = $gpoMap->getlayer(1);
$scale = $gpoMap->scale;


Thanks.

Hi, All

I have tried TestSuite from http://maps.dnr.state.mn.us/mapserver_demos/tests 
using mapserv_3.3,mapserv_3.4,and mapserv_3.5, but all failed. Here are the error messages:

-using mapserv_3.3/mapserv_3.4:

here is my input form:

I have modified the map file for mapserv_3.5, without attribute QUERY, and the result is:
msQueryByAttributes(): General error message. No query layer defined.

I try to add this input to the form:
<input type="hidden" name="qlayer" "value="world94"> 
the result is:
msQueryByAttributes(): Query error. Requested layer has no filter defined. 

Myquestion is: 
- what version of mapserver should be used for that Test Suite, or what wrong with these?
- how to use attribute FILTER in map file? I have tried alot of trial and error, but never success.
Would you give me a similar example (just a simple test for itemquery ) for mapserver version 3.5, please.

This solution, is a "server side" ... Ryan asked for a client side one!
That is something that can be executed from javascript running in the
browser to retrive
information dinamically ... The example could be a static page that
loads a map , a javascript in the page retrives the extent for
elaboration of following "views" of the map.
Is it so, Ryan?

I studied this possibility and concluded that is very complicated!
The main problem is making it compatible for different browser! 
Netscale has some method for loading a new file in a layer so you could
use it for loading a new javascript that "comunicates" some data to your
runnig javascript!
But this is not approved by w3c so not implemeted fro ather browser .. I
don't know MS-explorer but I heard about a "data-binding" for such
things ...

Other posibility could be:
1) using cookies ( cgi that sends the image could send a cooky too whith
required data)
2) Loading a file in a new window than accessing data in it from your
javascript ...
3) Use java

Hi,

I have a Shape file (streets layer) that is too big (> 200Mb)

When I query to this shape Mapserver works a lot of seconds (30 - 40) before
to diplay the map. How can I do for reduce the query time?

Thanks.

THe simplest solution is putting the layer twice into the mapfile. The first
one with your color coding, the second one for labeling (it may be
annotation type with one class). You can switch them ON/OFF together with
using the same GROUP name for both.

There are two ways to allow this in MS:

1. Using hatched symbols or only outlines for polygon fills (see
mapfile/symbolset documentation page)
2. Using TRANSPARENCY parameter to set the layer semi-transparent (also can
be found in documentation)

make sure you have a spatial index file. See utilities for shptree and
make sure you have *.qix for every *.shp.

Message-ID: <3DFF131E4E6D2D4198CDD758F35A5353010ABA22@postoffice.GASAI.Com>

I need help integrating a DGN file in a MapServer app using PHP MapScript.

Configuration:

  Win2K, IIS
  PHP 4.06
  php_mapscript_35.dll (1/11/2002) from DMSolutions site (this is in the 
    PHP4.06_ms5_final distribution folder)

Problem:

The DGN doesn't render...

No errors are returned, I just get a blank map window. The OGR part seems to
be working b/c if I change the source to shapefile, I can get a shapefile to
render (I converted the DGN to a shapefile in ArcView, and put it in the
same directory, if I toggle the CONNECTION lines in the mapfile below, the
shapefile works, the DGN doesn't).

As an aside, I can't seem to get the OGRINFO command to work... I downloaded
the GDAL binary for WINNT (http://www.remotesensing.org/gdal/). This is
somewhat confusing b/c the gdal documentation focuses on raster data. Is
there an OGRINFO utility that is different than the OGRINFO that is in the
GDAL distribution?

TIA

Message-ID: <18E0CC75605BD411907800508B8BB8D049E54E@odin.enator.dk>

Hi all,

I've been playing around with MapServer for a couple of weeks now, doing
mapping of SHP-files, OGR-files and spatial data from Oracle. MapServer is
pretty impressive!

I'm using version 3.5 for Windows with OracleSpatial support (got the binary
from http:parvillers.homeip.net/mapserver).

Since (I think) I found a couple of bugs/limitations in the OracleSpatial
support, I was wondering if anyone knows the current status on the following
issues:

1. labeling of OracleSpatial shapes not working (Dr. Watson crash on NT)
  try doing a LABELITEM "MyOracleSpatialColumnName"

2. multi-column expressions not working (Dr. Watson crash on NT)
  try doing a: EXPRESSION ([Column1] > 225 AND [Column2] > 315)

3. item query of OracleSpatial shapes not working
  see Rodrigo's mail from 11. Jan. 2002 in the mailing list

Any links to MapServer with OracleSpatial support would also be appreciated.

Regards
Bjarni Thor Pjetursson

Chip,

It's hard to know why this isn't working, but I would suggesting getting
ogrinfo working is the critical first step.  They you can verify the extents
and types of features available.

The ogrinfo within the GDAL tree is the real and only one.  Have you been able
to build or download a recent ogrinfo?  Does it work?  If not how does it fail?
I suggest you take this up directly with me by email.

I have just released GDAL/OGR 1.1.7 a few minutes ago, and perhaps I should
prepare a corresponding binary release for Windows since the most recent
binary release is rather out of date, and likely predates alot of my work
integrating DGN in OGR properly.

Best regards,

Hi There,

 We have used recently here DGN files through OGR support and It was working ok.
I think that the dll you got did not include the latest GDAL/OGR library (with
proper support of DGN). I could send you directly the latest php_mapscript.dll
compiled for php4.1.2 if you are able to updgrade your php.
 I am also going to put a new version on our download site later today.

Message-ID: <F236JFUZJPg7g0bBVuN00019231@hotmail.com>

Hello,

I have been able to compile mapserver 3.5 on Linux/Suse 7.3 and got the demo 
running. Now I am thinking of using Java mapscript within Jsp Pages.
Does anybody know how to go about this. Do I have to use Swig to create the 
Java sources from the nightly builds or are there other Java sources 
available. Is the functionality or reliability of Java mapscript similar to 
that of the Perl or PHP versions or are there any limitations. Are there any 
manuals covering the usage of Java mapscript. And so on..
I would appreciate any information or hints concerning the compilation and 
usage of Java mapscript in the linux environment.

Thanks in advance
Andreas Hirner

Hi Stefano,
I think $gpoMap->scale is only a read only function, and must be assigning
this values to your $scale variable which is not part of the $gpoMap
object, I think you should trying using the set method:
$gpoMap->set("scalebar", "value of scale you want");
Please check the correct syntax for scalebar.

Message-ID: <4C5998A3E78C674A92183D4813806E82035CA0@ytcmail.yorktel.com>

I'm running the mapserver 3.5 CGI version and HTML template on a Linux system.

I followed Rod's guidance of Feb 11 and put a javascript function called DoQuery in my HTML file to call a Perl program (Rod's original version calls a PHP program, I figured it should work with Perl).

Now my question is how do I specify when this DoQuery function is called.  I'm still getting the error message of function not implemented when I execute the new HTML.

  ny = eval( size[1] ) - 1;

  minx = eval( ext[0] );
  miny = eval( ext[1] );
  maxx = eval( ext[2] );
  maxy = eval( ext[3] );

  qx1 = x1*(maxx - minx)/nx + minx;

Patricio:
I use polygon hatch this way (and it works perfect for me):

In the .map file:

LAYER
   NAME "cobertura"
   TYPE POLYGON
   STATUS ON
   DATA cubrimiento
   TOLERANCE 5
   CLASSITEM 'Nombre'
   CLASS
     EXPRESSION /./
     OUTLINECOLOR 0 102 0
     COLOR 102 102 102
     SYMBOL diagonal_hash
     TEMPLATE "ttt"
   END
END # Cobertura

And in the symbol file:
----------------------

Symbol
   Name 'diagonal_hash'
   Type VECTOR
   Points
     3 3
     3 3
   END
END #diagonal_hash


Hope that helps,

I'm running Mapserver 3.5 on a Linux system.  When I run the CGI version and HTML template with map file I have the display of maps without any problem.

I compiled and installed mapscript perl version.

When I run dump.pl from examples I get can't load '......mapscript.so' for module mapscript: ......mapscript.so: undefined symbol: OCIErrorGet at ......DynaLoader.pm line 200.
at .....mapscript.pm line 7

What am I missing?

Bjarni:

It is interesting that I just sent off a question related with your item 3.

I'm running the Mapserver on a Linux system and I don't have any problem with what you described as in 1 and 2.  Since you got our favorite Dr. Watson involved, do you want to try to recompile your Mapserver or if you can find another Windows box with less applications and try on it?  This may be a good incentive for you to get your hands wet on Linux/Unix system and it probably benefits in the long run.

Hi all,

I've been playing around with MapServer for a couple of weeks now, doing
mapping of SHP-files, OGR-files and spatial data from Oracle. MapServer is
pretty impressive!

I'm using version 3.5 for Windows with OracleSpatial support (got the binary
from http:parvillers.homeip.net/mapserver).

Since (I think) I found a couple of bugs/limitations in the OracleSpatial
support, I was wondering if anyone knows the current status on the following
issues:

1. labeling of OracleSpatial shapes not working (Dr. Watson crash on NT)
  try doing a LABELITEM "MyOracleSpatialColumnName"

2. multi-column expressions not working (Dr. Watson crash on NT)
  try doing a: EXPRESSION ([Column1] > 225 AND [Column2] > 315)

3. item query of OracleSpatial shapes not working
  see Rodrigo's mail from 11. Jan. 2002 in the mailing list

Any links to MapServer with OracleSpatial support would also be appreciated.

Regards
Bjarni Thor Pjetursson

Hi Chip, one thing to keep in mind is that STYLEITEM "AUTO" may not always
give you the results you were anticipating (if you are using this feature).
It was kind of funny because this automatic styling was working great - but
I thought I kept getting a blank screen.  Indeed, this was a "user-related
issue" :)  What was happening was that MapServer was rendering the linework
properly but it was colouring it white - which was the same colour as my
map background...you guessed it...my map looked blank.  Once I went into
the map file and change the IMAGECOLOR setting to something other than
white - oddly enough the map started to appear :)  So, you may want to try
the same to make sure that it's not something that simple.  Also, does it
appear that MapServer is taking time to render the DGN data?  I mean, does
it take any longer to draw your map with or without the DGN layer loading?
If there is no "time" difference, I would assume it's not loading at all.
But even if the background is the same colour as the features, it probably
would still take a tad bit longer to render your map.

Enjoy.
Tyler

I need help integrating a DGN file in a MapServer app using PHP MapScript.

Configuration:

  Win2K, IIS
  PHP 4.06
  php_mapscript_35.dll (1/11/2002) from DMSolutions site (this is in the
    PHP4.06_ms5_final distribution folder)

Problem:

The DGN doesn't render...

No errors are returned, I just get a blank map window. The OGR part seems
to
be working b/c if I change the source to shapefile, I can get a shapefile
to
render (I converted the DGN to a shapefile in ArcView, and put it in the
same directory, if I toggle the CONNECTION lines in the mapfile below, the
shapefile works, the DGN doesn't).

As an aside, I can't seem to get the OGRINFO command to work... I
downloaded
the GDAL binary for WINNT (http://www.remotesensing.org/gdal/). This is
somewhat confusing b/c the gdal documentation focuses on raster data. Is
there an OGRINFO utility that is different than the OGRINFO that is in the
GDAL distribution?

TIA

Andreas,

This is what I did.

I got the mapserver source code and untarred it and did the following

./configure --with-jpeg --with-gd --with-proj 
--with-gdal=/usr/local/bin/gdal-config
make

Then I got the SWIG Version 1.3.11 source.

./configure --with-javac=/usr/java/j2sdk1.4.0/bin/ 
--with-java=/usr/java/j2sdk1.4.0/bin/ 
--with-javaincl=/usr/java/j2sdk1.4.0/include/
make
make install

I created a directory called java in mapserver-src/mapscript and created 
a symlink for mapscript.i inside it.  (In the new nightly builds, you 
might not need this step since it should be already in there)

/usr/local/bin/swig -java -shadow -package mapscript mapscript.i

It created some java files.
Then I did
FLAGS="-DUSE_PROJ -DUSE_PROJ_API_H -DUSE_GD_PNG -DUSE_GD_JPEG 
-DUSE_GD_WBMP -DUSE_GD_FT -DUSE_WMS -DUSE_TIFF -DUSE_JPEG -DUSE_EPPL 
-DUSE_GDAL"gcc -fpic -c $FLAGS -I/usr/java/j2sdk1.4.0/include 
-I/usr/java/j2sdk1.4.0/include/linux mapscript_wrap.c
gcc -fpic -shared -o libmapscript.so -L/usr/lib -lgd -ljpeg -lfreetype 
-lpng -lz -ltiff  -L/usr/local/lib -lgdal.1.1 -lproj mapscript_wrap.o 
../../libmap.a


Java programs didn't compile right off the bat. I need to correct all 
those 'long' variable types and return types. Then it compiled. (New 
nightly build should compile clean)

In tomcat, I added the following line in /etc/tomcat4/conf/tomcat4.conf

export LD_LIBRARY_PATH=/opt/mapserver/mapscript/java:$LD_LIBRARY_PATH

I have the mapserver installed on /opt/

I have attached a servlet sample .

Thanks
Sathis

Subject: [mapserver-users] Accessing external files using javascript (
	other)
Message-ID: <614FCE5F14A6D41180C200010240D6A29A44FA@LINNMS>


Thanks to Giorgio, Robert Crossley, Pushkar S. Pradhan, Bud etc. for help on
accessing external files.

MapServer and this mailing list are the bomb!  I love this stuff.  I'm
working on a slick interface for public access to county records.  I had
wanted to access files on the client and server side.

On the server side, I'm going with asp in one frame to control the other (as
long as our IT guys stick with ms server).

On the client side, I haven't gotten there yet and I'm not sure if I need to
but I explored the data-binding in explorer and it looks sweet.  I demo'd an
easy way to use a delimited text file (as a url path) as a data source.
Very nice and easy on IE but of course this doesn't work on Netscape.  Is
anyone out there surprised?

Thanks again,

Hi "Untung Rasidin"

I use to convert MAPINFO file to SHAPE, using Universal Translator in
MapInfo.
I have perceived that a described attribute with more than eight characters
the MapServer does not recognize.
Thus, transforms ABBREVNAME for ABBRNAME, and try again.

I do not know explain why.

Ferrari, Gabriel

Message-ID: <3DFF131E4E6D2D4198CDD758F35A5353010ABA2F@postoffice.GASAI.Com>

OK,

The problem was that the DLL I was using - php_mapscript_35.dll (1/11/2002)
from DMSolutions site (this is in the PHP4.06_ms5_final distribution folder)
- was apparently compiled with an earlier version of GDAL that did not
support DGN.

I upgraded to 4.12 and used the mapscript dll from the
php4.1.2_php_mapscript_36-dev_libwww.zip on DMSolutions site and it works
great.

Thanks for everyone's help.

You can use '%%' in a printf format string to output a '%' char, 
e.g.
printf("Apache runs on more than 50%% of the servers on the Internet");

Message-ID: <3DFF131E4E6D2D4198CDD758F35A5353010ABA32@postoffice.GASAI.Com>

I want to render labels out of a DGN file, using OGR.

I can get the labels to show up if I simply define an annotation layer,
however, they are not rotated or scaled at all (they are in the original
DGN).

I get lost in the documentation if I try to use any of the following:

  LABELITEM "string"
  LABELSIZEITEM "size"
  LABELANGLEITEM "angle"

The HOW-TO (http://mapserver.gis.umn.edu/doc/ogr-howto.html#d41e528) says
the following:

  The text string is mapped to CLASS.TEXT
  Text color is mapped to CLASS.LABEL.COLOR
  Text background color is mapped to CLASS.LABEL.BACKGROUNDCOLOR
  Text height is mapped to CLASS.LABEL.SIZE
  Text angle is mapped to CLASS.LABEL.ANGLE

What does this translate to in a map file? Here's a snippet of OGRINFO for
one of the features I want to label:

OGRFeature(elements):28877
  DGNId (Integer) = 28877
  Type (Integer) = 17
  Level (Integer) = 5
  GraphicGroup (Integer) = 0
  ColorIndex (Integer) = 3
  Weight (Integer) = 2
  Style (Integer) = 0
  _gv_color (String) = 1.000000 0.000000 0.000000 1.0
  _gv_ogrfs (String) = LABEL(t:"AP141")
  POINT (-1045674.733 -93744.598)

Message-ID: <Pine.GSO.4.33.0204181641200.22445-100000@agassiz.cs.und.edu>

greetings!  i have a couple things...

first, when i run my script, everything displays as it should initially,
but if i look in my web log, there are a couple references to "(in
cleanup) not a hash reference...(blah).../mapscript.pm line 1801"  i've
seen other lines pop up every now and then for other objects, but 1801 is
the only consistent one.  just wondering if anybody in mapscript land
might know what's causing that.  the only thing i can think of is i'm
using mapscript to build everything from scratch without a mapfile or
anything else.  is that a valid possibility??

second, i need guidance on getting a pan-and-zoom interface to work.  i've
toyed with porting the php example from the online docs to perl and also
with a recent post from lowell, but to no avail.  methinks most of my
problem is because i don't really understand extents and what they
represent well enough to manipulate them the way i need.  if anyone
has any good references or comments on that, i'd appreciate it greatly.
also, is it possible that the aforementioned problem may be affecting my
pan/zoom logic?  just a thought...

anyhoo, thanks in advance for your help!  sorry for being so long-winded!

Message-ID: <000a01c1e77a$14ffcf60$3e01a8c0@ivvaachen.de>

Thank you very much for the links.

The article has some new aspects, even though it is only an introduction
that can of cause not
go into details. For example it mentiones that there can occure problems
displaying an image that
has been resized. Maybe I have exactly the problem that the extend of my
image does not fit to
the other data.

And what about the demo? I unpacked it and tried to display the landsat.tif
with Paint Shop Pro.
But I got the message "this is not a valid tiff image". ArcExplorer gave me
a similar error message,
but displayed the shapefiles without any problems. Seems that I do not have
any luck with tiffs :-(

This error is corrected by the testsuite version for mapserver 3.5. Insead
of
LAYER
      :
   CLASS
         :
   END
   QUERY
      TEMPLATE name.html
   END
END
for mapserver 3.5 you have to write
LAYER
      :
   CLASS
         :
      TEMPLATE name.html
   END
END

Even using the testsuite version for mapserver 3.5 you might have to correct
something.
I had to add the following to all map files that had no web object defined:
WEB
    TEMPLATE name.html
END

Because I have no truetype support I also commented out the following lines:
#FONSET ../fonts/fonts.list
#TYPE TRUETYPE
#FONT arial

Now the Item/value queries and the dynamic queries work correct with my
mapserver.
But I have still a problem with the point query examples and the pan and
zoom example.
For them I get the following error message:
msGetBitmapFont(): GD library error. Invalid bitmap font. Must be one of
tiny, small, medium, large or giant

Has someone an idear how I can correct this?

Subject: [mapserver-users] Problems displaying tiffs and jpegs
Message-ID: <000f01c1e79a$baa1cbb0$3e01a8c0@ivvaachen.de>

Just for testing, I now tried to display images in .jpg format instead of
.tif format.
But I got the same result - nothing shows up. I think I'm doing something
really wrong.

I used the jpegs created through mapserver in the /temp/ directory (output
IMAGETYPE JPEG).
After converting them to greyscale images with Paint Shop Pro, I had two
jpeg images
country.jpg and lakes.jpg. In the world files for these jpegs, I used the
minx and the
maxy extend from the shapefiles.

country.wld:
-----------------
0.6
0.0000000000
0.0000000000
-0.6
388107.634400379
5310243.30613897

lakes.wld:
-----------------
0.6
0.0000000000
0.0000000000
-0.6
393234.393701
5303964.87675

To display the jpegs I modified the .map file from the demo like this:

#
# Start of layer definitions
#

LAYER
  NAME ctybdpy2
  TYPE RASTER
  STATUS DEFAULT
  DATA country.jpg
END

LAYER
  NAME lakespy2
  TYPE RASTER
  STATUS OFF
  DATA lakes.jpg
  CLASS
    COLOR 49 117 185
  END
END

It would be gread, if you could help me, because by now I'm really stuck.
Thanks, Nicole.

Hey there:

Answering your questions:

1. labeling of OracleSpatial shapes not working (Dr. Watson crash on NT)
  try doing a LABELITEM "MyOracleSpatialColumnName"

The problem with the labelitem, actually, is the way I'm fecthing data in a
buffer when querying the database for it. This is not an infamous
hard-to-find bug. I'll have it fixed soon. I my last post, I mentioned I
have separated some time in the end of this month to make things work. Do
you have other *item statements in the mapfile? Like classitem? That's
usually when this bug appears, when 2 or more *items are used.

2. multi-column expressions not working (Dr. Watson crash on NT)
  try doing a: EXPRESSION ([Column1] > 225 AND [Column2] > 315)

Same reason as above.

3. item query of OracleSpatial shapes not working
  see Rodrigo's mail from 11. Jan. 2002 in the mailing list

Wait for the end of the month =)

Regarding some documentation, I would be pleased to help anyone who'd wish
to create a tutorial. I think this tutorial could extend the one that is
presented in the Oracle Spatial reference (section 2.1 - cola markets).
Starts with data creation using SDO SQL and ends up with MapServer display &
query.

Rod.

Hi all,

I've been playing around with MapServer for a couple of weeks now, doing
mapping of SHP-files, OGR-files and spatial data from Oracle. MapServer is
pretty impressive!

I'm using version 3.5 for Windows with OracleSpatial support (got the binary
from http:parvillers.homeip.net/mapserver).

Since (I think) I found a couple of bugs/limitations in the OracleSpatial
support, I was wondering if anyone knows the current status on the following
issues:


Any links to MapServer with OracleSpatial support would also be appreciated.

Nicole,

The .wld files are in some kind of projection in METERS. What does the
top of your mapfile look like? Have you specified a PROJECTION .. END?
What are your EXTENTS? What are your UNITS?

I think maybe these do not match your images. Which would account for
your images not showing up.

Hey there:

What you need to do is to send the query to your querymap.pl, instead of
sending it to mapserver's CGI. My HTML coding is quite different from yours.
Go to http://g10.cttmar.univali.br/rastro/, click in "vers?o de
demonstra??o", and you'll see what I mean.

Anyway, I'll try to give you some hints on how you can proceed from the code
you have now.

1) You will have to change the action in your form accordingly, using
javascript. If the user selects "query" for "mode", then your action is
"/cgi-bin/querymap.pl"; likewise, when "mode" is "browse" action is set to
"/cgi-bin/mapserver/mapserv". You may use the onclick event in both of your
"mode" radio button tags.

2) You will have to change querymap.pl to work with the physical (image),
not logical (map) coordinates. This means that you remove DoQuery from your
HTML, and put its "idea" in perl. In your case you won't have a rectangle to
query, but a point (img.x and img.y must be used for qx1 and qy1), and
imgext is the variable which's holding your extent values for translating
physical to logical units. nx and ny are constants based on the size in
pixels of your image.

I'd love to give code samples, but kinda in a hurry right now...

Cheers,
Rod.

Subject: [mapserver-users] oraclespatial query through CGI


I'm running the mapserver 3.5 CGI version and HTML template on a Linux
system.

I followed Rod's guidance of Feb 11 and put a javascript function called
DoQuery in my HTML file to call a Perl program (Rod's original version calls
a PHP program, I figured it should work with Perl).

Now my question is how do I specify when this DoQuery function is called.
I'm still getting the error message of function not implemented when I
execute the new HTML.

<script language="javascript">
function DoQuery( url_query, x1, y1, x2, y2 )

  ext = imgext.split( /\+/ );

  nx = eval( size[0] ) - 1;
  ny = eval( size[1] ) - 1;

  minx = eval( ext[0] );
  miny = eval( ext[1] );
  maxx = eval( ext[2] );
  maxy = eval( ext[3] );

  qx1 = x1*(maxx - minx)/nx + minx;
  qx2 = x2*(maxx - minx)/nx + minx;

I extracted the landsat.tif from the link and it came up fine in Gimp & ImageMagick. I noticed it is LZW compressed and I'm not sure that ArcExplorer supports LZW compression due to copyrights and for some reason I can't reach ESRI's site. If you have a good internet connection I can e-mail the landsat.tif saved with packbits compression instead off-list.

Whithout diving into it further to eliminate the messages a quick fix is to exclude the perl -w option when running the script AFTER you are sure your code is clean and any warnings point elsewhere.
As far as your zoom/pan problem goes could you explain exactly what is happening/what isn't happening. I'm afraid I'm not following what the problem/error is.

Message-ID: <3CC02D9C.6A0F849@ikf.nlh.no>

Is there a way to specify which attributes should be returned
on a WMS GetFeatureInfo request?
I am currently using the 3.5 Mapserver release.

The support that I have found is:
DUMP=false stops attributes from being shown when the request
is for GML but not when the request is for something else
(plain text return).

Perhaps a mapserver "wms-tag" would do, something like:
 "ms-wms-public_attributes" "Name, Hair Color, Job"

Thanks, Lowell and Steve.

It took me quite a few tries to recompile and I finally got both oraclespatial and perl mapscript working.  Well, my map based on oraclespatial is still running, as far as the perl mapscript, I havn't been able to have a display from mapquakes yet but at least we got rid of the mapscript.so error message.

Not at the moment. I don't recall seeing that level of control in the WMS spec or I imagine it would already have been added. The DUMP parameter is there simply to prevent wholesale download of the raw data (i.e. coordinate data). It has no effect otherwise.

Is there a way to specify which attributes should be returned
on a WMS GetFeatureInfo request?
I am currently using the 3.5 Mapserver release.

The support that I have found is:
DUMP=false stops attributes from being shown when the request
is for GML but not when the request is for something else
(plain text return).

Perhaps a mapserver "wms-tag" would do, something like:
 "ms-wms-public_attributes" "Name, Hair Color, Job"

1. everytime you draw the map, you need to set the mapextent. 

2. if you are doing this for the very first time, you would usually start
with the maximum extent of your map. otherwise, you would start with the
current extent of the map.

3. so, let's reiterate... the first time is easy because you start with the
maxextents. at that point in time, you send the current extent (which
happens to be maxextents right now) to the client. you usually do that as
hidden form fields.

4. now the map is sitting on the client. the user chooses to zoomin. the act
of zooming in sends back to the server the point-of-click of zoomin, a
(usually) preset zoomfactor, and the current extents that were in the hidden
fields.

5. back at the server, you now start with these current extents and apply
the zoomfactor to get the new current extents. and the process in #1 above
restarts.

did this make sense?

Subject: [mapserver-users] Problem setting name attribute of classObj with Python Mapscript
References: <4C5998A3E78C674A92183D4813806E82035CA3@ytcmail.yorktel.com>
Message-ID: <3CC07DE7.60908@i3.com>

Have any Python (or other) Mapscript users found trouble with
setting the "name" attribute of a classObj?  I've been through
the list archives but haven't found anything of help.

In short, I'm unable to set the name attribute of a classObj
by statements like

   myclass.name = "FOO"

Am using Python Mapscript built from the 3.5 Win32 distribution.

Here is the relevant code of my script. Am looping over several
layers in a list and ftab['name'] is bound to a different value
each time.

   ...
   class_OK = classObj(layer)
   class_OK.setExpression("/1/")
   class_OK.name = ftab['name'] + "_OK"
   class_OK.outlinecolor = purple # 255,0,255

   class_DEF = classObj(layer)
   class_DEF.name = ftab['name'] + "_DEF"
   class_DEF.color = red
   class_DEF.outlinecolor = purple
   class_DEF.label.color = black
   class_DEF.label.type = MS_BITMAP
   class_DEF.label.size = MS_TINY
   class_DEF.label.position = MS_CC
   class_DEF.label.force = MS_TRUE
   ...
   map.save(...)

The map is drawn and looks fine, but no legend.  Examining the
map file that was written, I see that everything is in its
place except that there is no NAME for either of the two classes
I've defined for every layer.  Here is an excerpt from the map
file:

   CLASS
     EXPRESSION /1/
     MAXSIZE 100
     MINSIZE 1
     OUTLINECOLOR 255 0 255
     SIZE 1
     SYMBOL 0
   END
   CLASS
     COLOR 255 0 0
     LABEL
       SIZE TINY
       TYPE BITMAP
       BUFFER 0
       COLOR 0 0 0
       FORCE TRUE
       MINDISTANCE -1
       MINFEATURESIZE -1
       OFFSET 0 0
       PARTIALS TRUE
       POSITION CC
     END
     MAXSIZE 100
     MINSIZE 1
     OUTLINECOLOR 255 0 255
     SIZE 1
     SYMBOL 0
   END

Am stumped and grateful for any suggestions.

thanks,
Sean

You can use truetype line symbols for it:

1. Define true type symbol, e.g.:

SYMBOL
  NAME "arrow"
  TYPE "truetype"
  FONT "tahoma" #or what you have set in your fontset file
  GAP -10 #the value MUST be negative to enforce "as digitized" orientation
  CHARACTER ">" #or your own defined arrow symbol
END

2. then in your map file layer class definition

CLASS
  SYMBOL "arrow"
  SIZE 10
  COLOR etc...
END

You can also set OVERLAYSYMBOL to combine arrows with lines etc... You can
also use POSITION parameter in the symbol definition to set the symbol
above/under line etc...

Hey there:

What you need to do is to send the query to your querymap.pl, instead of
sending it to mapserver's CGI. My HTML coding is quite different from yours.
Go to http://g10.cttmar.univali.br/rastro/, click in "vers?o de
demonstra??o", and you'll see what I mean.

Anyway, I'll try to give you some hints on how you can proceed from the code
you have now.

1) You will have to change the action in your form accordingly, using
javascript. If the user selects "query" for "mode", then your action is
"/cgi-bin/querymap.pl"; likewise, when "mode" is "browse" action is set to
"/cgi-bin/mapserver/mapserv". You may use the onclick event in both of your
"mode" radio button tags.

2) You will have to change querymap.pl to work with the physical (image),
not logical (map) coordinates. This means that you remove DoQuery from your
HTML, and put its "idea" in perl. In your case you won't have a rectangle to
query, but a point (img.x and img.y must be used for qx1 and qy1), and
imgext is the variable which's holding your extent values for translating
physical to logical units. nx and ny are constants based on the size in
pixels of your image.

I'd love to give code samples, but kinda in a hurry right now...

Cheers,
Rod.

I'm running the mapserver 3.5 CGI version and HTML template on a Linux
system.

I followed Rod's guidance of Feb 11 and put a javascript function called
DoQuery in my HTML file to call a Perl program (Rod's original version calls
a PHP program, I figured it should work with Perl).

Now my question is how do I specify when this DoQuery function is called.
I'm still getting the error message of function not implemented when I
execute the new HTML.

I did leave out some of the details from my explanation. Here is a more
detailed explanation. I am using PHP methods here, but they should be very
similar to the Perl methods... compare the docs, or better yet, parse
through the mapquakes.pl SDL sent you.

1. everytime you draw the map, you need to set the mapextent. 

2. if you are doing this for the very first time, you would usually start
with the maximum extent of your map. otherwise, you would start with the
current extent of the map. The best way to determine that is to use sessions
(something like Session.pm on Perl should do the trick). Else, you could
set/get cookies or some http_var to the same effect. Using sessions,

assuming $maxextent is a session array

if(!isset($maxextent) ) {
  $curextent[minx] = $mapObj->extent->minx;   // array to hold the curextent
  $curextent[miny] = $mapObj->extent->miny;
  $curextent[maxx] = $mapObj->extent->maxx;
  $curextent[maxy] = $mapObj->extent->maxy;
  $maxextent = $curextent;                    // copy curextent to maxextent
  // set the mapObj to the current extent
  $mapObj->setextent($curextent[minx], 
                     $curextent[miny], 
                     $curextent[maxx], 
                     $curextent[maxy]);
} 

// if form variables are defined...
// $maxextent is set, so this is a return view.
// set the curextent using the values received from 
// the form variables
if(isset($minx)) {
  $curextent[minx] = $minx;
  $curextent[miny] = $miny;
  $curextent[maxx] = $maxx;
  $curextent[maxy] = $maxy;
}

// set the mapObj to the current extent
$mapObj->setextent($curextent[minx], 
                   $curextent[miny], 
                   $curextent[maxx], 
                   $curextent[maxy]);

// create a rectObj with curextent
$curExtObj = ms_newRectObj();

3. now you can do whatever else you want to do to the map... zoomin,
zoomout, pan, etc. for example, if you wanted to zoom in using a zoomfactor
of 3 you would use the following code

// create a point object at the point of click
// point of click is usually returned by the browser
// keep in mind, the x,y are in screen pixel coords
// you have to create a point using geog coords, so
// apply the requisite transformation
$pointObj = getMouseClick($x, $y);

// now set new extent using the zoompoint method
$mapObj->zoompoint(3, $pointObj, $map_width, $map_height, $curExtObj);

// now draw the map
$imgObj = $mapObj->draw();
$imgUrl = $imgObj->saveWebImage(MS_PNG, 0, 0, -1);

make sure when you send the above image back to the user that you send the
bounding box (minx, miny, maxx, maxy) as hidden form fields so you can reuse
them the next time.

3. so, let's reiterate... the first time is easy because you start with the
maxextents. at that point in time, you send the current extent (which
happens to be maxextents right now) to the client. you usually do that as
hidden form fields.

4. now the map is sitting on the client. the user chooses to zoomin. the act
of zooming in sends back to the server the point-of-click of zoomin, a
(usually) preset zoomfactor, and the current extents that were in the hidden
fields.

5. back at the server, you now start with these current extents and apply
the zoomfactor to get the new current extents. and the process continues...

this should get you going. As I said, the Perl logic will be similar (in
fact, any scripting logic will be similar... the syntax is all documented).

Hth.

pixels of your image.

I'd love to give code samples, but kinda in a hurry right now...

Subject: [mapserver-users] oraclespatial query through CGI


I'm running the mapserver 3.5 CGI version and HTML template on a Linux
system.

I followed Rod's guidance of Feb 11 and put a javascript function called
DoQuery in my HTML file to call a Perl program (Rod's original version calls
a PHP program, I figured it should work with Perl).

Now my question is how do I specify when this DoQuery function is called.
I'm still getting the error message of function not implemented when I
execute the new HTML.

Oops.. gave you the wrong URL. This one doesn't make queries.... Try this:

It also was designed for IE only.

Hey there:

What you need to do is to send the query to your querymap.pl, instead of
sending it to mapserver's CGI. My HTML coding is quite different from yours.
Go to http://g10.cttmar.univali.br/rastro/, click in "vers?o de
demonstra??o", and you'll see what I mean.

Anyway, I'll try to give you some hints on how you can proceed from the code
you have now.

1) You will have to change the action in your form accordingly, using
javascript. If the user selects "query" for "mode", then your action is
"/cgi-bin/querymap.pl"; likewise, when "mode" is "browse" action is set to
"/cgi-bin/mapserver/mapserv". You may use the onclick event in both of your
"mode" radio button tags.

2) You will have to change querymap.pl to work with the physical (image),
not logical (map) coordinates. This means that you remove DoQuery from your
HTML, and put its "idea" in perl. In your case you won't have a rectangle to
query, but a point (img.x and img.y must be used for qx1 and qy1), and
imgext is the variable which's holding your extent values for translating
physical to logical units. nx and ny are constants based on the size in
pixels of your image.

I'd love to give code samples, but kinda in a hurry right now...

Cheers,
Rod.

 I need to locate a point using itemquerymap (does anybody know

 Then I need to pan around this location. This is a basic functionality
 for any GIS-like application. According to this, I need to obtain the selected point coordinates 
(at least), or,  for more than one selected point ,the extent or extent center of all
 selected features.
Stephen Woodbridge says that most people do this using mapscript. OK, can anybody be more

I got the last nightly-build working.

When I try to display roads from a Postgis-Table with java-mapscript I 
get the following error:

"prep_DB:Error executing POSTGIS  DECLARE statement (0.6 failed - 
retried 0.5 and it failed too)"

Looking in the Logfile from the PostgresqlDB following is written twice:

"ERROR: BOX3D parser - number of points should be exactly 2"

Using the exactly the same map-File with mapserver-cgi everything is 
working fine. Specified roads are drawn in the png. Can anyone give some 
hints why it does not work with java-mapscript?

Thanks

Well this does not answer your question, but points at another problem.
Your PHP is an apache DSO (because you compiled it --with-apxs) this is
not PHP was a CGI which is required for PHP/Mapscript. You will get all
kinds of runaway process issues, random PHP crashes and other issues if
you use your system in this configuration.

If you want PHP as a DSO for other applications that is fine, but you
need to build a CGI version for use with Mapscript and change you php
file extensions to be different and configure apache to use the CGI for
PHP/mapscript file extension.

There has been a lot writen about this in the archives and DM Solutions
has a detailed instructions on their site. Also look at wiki which is
probably the best starting point.

I understand that this is not possible using regular MapServer features.
How can I do this using MapScript ?

This feature is not implemented in directly in Mapserver. MapScript has
a queryByAttributes() function that might work, but I am not sure how it
works.

Can someone from DM Solutions comment on this?

I wrote my own GeoCoder in C that works off the shape files but it is
somewhat targeted at US Census data. You can see it at
http://swoodbridge.com/cgi-bin/geo enter and address east of the
Mississippi in the US.

Some other people were working on an OpenSource version - you might want
to check the list archives for more information.

You could build something to do this with shapefiles in Perl or
PHP/Mapscript because both of these can open *.dbf files where all the
attributes are stored and scan the records.

I hope this helps,

Hi,

does anybody now a symbol for a dotted line which allows scaling of its with
and gap simultaneously?

example: having a dot - space - dot - space .... symbol,
and giving a size of 5, I would like to have 5 px sized (circular) dots and 
5 px wide gaps between them. 

Any help will be appreciated

I'm using mapscript with Perl because I'm having trouble with my PHP.  Given a little more time I'll try to resolve my PHP and Oracle issue (not related with Mapserver).  Sorry can't be any assistance right now.

I am trying to build ms_3.5 with PHP 4.0.6. I have Apache 1.3.24 
compiled with apxs. When I `make' it churns for a while and then issues 
the following error...

cc: cannot specify -o with -c or -S and multiple compilations
make[1]: *** [php_mapscript_util.o] Error 1




mapserv itself gets compiled and is sitting in the mapserver src 
directory. Here is the version info

[localhost:~/Projects/mapserver_3.5] pkishor% ./mapserv -v
MapServer version 3.5 OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP SUPPORTS=PROJ 
SUPPORTS=TTF SUPPORTS=WMS_SERVER INPUT=EPPL7 INPUT=JPEG INPUT=SHAPEFILE

It seems the error is only when building PHP/Mapscript module.

Any help will be much appreciated.

Nicole,

The .wld files are in some kind of projection in METERS. What does the
top of your mapfile look like? Have you specified a PROJECTION .. END?
What are your EXTENTS? What are your UNITS?

I think maybe these do not match your images. Which would account for
your images not showing up.

Something weird with the listserv... I sent this message yesterday about 
10 mins after my initial incorrectly titled message. This one never 
appeared on the list. Many other messages were very late in coming 
(several hours).

Anyway, I am re-sending this for the archives for the solution (see 
below). And a big thanks to everyone who responded to me directly.

==========

I sent this message earlier with the wrong subject line. This is for the 
archives with the correct subject.

I also found the answer to this...

seems to be a platform-specific peculiarity. I am using cc on OS X, but 
reported on a few other platforms as well. The very first uncommented 
line in the Makefile under the mapscript/php3 directory was like so...

CC =     cc cc  -I. -I..

I deleted one of the two cc so the line became

CC =     cc  -I. -I..

everything worked after that.

hth someone.

Thanks Steve. Your answer set me on the correct path, however, I am 
still not close to nirvana.

I looked at your notes on the wiki. While it says that PHP as a CGI is 
required for Mapscript, you also note that I could run with PHP as a 
DSO... just that I would experience random weird behaviour. I am 
assuming though that PHP as a CGI _is required_ for Mapscript.

Anyway, I rebuilt PHP as a CGI but I still get a perplexing behaviour 
from Apache. It simply refuses to run the php scripts. I get the famous

(8)Exec format error: exec of /Library/WebServer/Documents/phpinfo.php 
failed
[client 192.168.123.253] Premature end of script headers: 
/Library/WebServer/Documents/phpinfo.php


Yes, I have the requisite AddType and AddHandler statements present, and 
yes, my scripts are chmod-ed to be executable. Apache just doesn't seem 
to know where my php bin is. I even put a ScriptAlias to the php bin, 
and turned on Options +ExecCGI... no luck.

Of course, if I put a shebang line (#!/usr/local/bin/php -q) at the top 
of the script it works. The "-q" is important so the script doesn't spit 
out the shebang line itself.

I have spent two entire sleepless nights on this now (well, including 
all the thousand prerequisites that I had to recompile... what a house 
of cards). I am sure I will find an answer to this sooner or later.

But at this time I can't possibly recommend PHP/Mapscript for MacOS X 
users. They would be much, much better off sticking with Perl/Mapscript 
which compiles like s*** through goose, and works splendidly with 
mod_perl. The problem is the OS X comes with Apache and PHP (as DSO) 
precompiled and installed. Since, PHP/Mapscript can only work as a CGI, 
one has to recompile Apache as well and then compile PHP. Recompiling 
Apache means that one has to recompile Perl as well (and mod_perl, if 
desired) in order to make everything else work smoothly. Uggghhhhhh!

Still crazy after all these years,

I believe Steve is correct. You will need to select the point by attribute first then read the coordinates for the point and buffer them and use that buffer as your new mapextent. From that you can create a drawQuery map that can be panned & etc.
This link has example code regarding the DBFInfo Object:

This link has example code regarding reading the extents for a selected shape:

Note that it is not mandatory to recompile Apache in order to run PHP as
a CGI even if it was compiled with the PHP DSO already... you can keep
your original Apache and bypass the PHP DSO, see the section "If your
server came preloaded with PHP as an Apache DSO" at the bottom of the
following Wiki page: 
  http://mapserver.gis.umn.edu/cgi-bin/wiki.pl?PHPMapScriptCGI

Message-ID: <3CC41AAF.9AD28C67@aris.nl>

Hi,

When I zoom in on a tif-raster, it is shifted. Looks like the amount
of shift depends on cell size of the raster. When I check the same
dataset in ArcView, all looks normal.
Have a look at http://www.webmap.nl/webmap/pub/berend/index.html to
see what I mean.
I'd like to know if this is a bug, and if so, if it's fixed in 3.5 
(We're using 3.4 now).

Thx, Berend

You do not need access to an Apache source tree in order to compile PHP
as a CGI.  A CGI is by definition a standalone executable, and for this
reason has no depency on any web server.  Try removing the --with-apxs
and/or --with-apache directives in your PHP configure options and it
will then build as a CGI without any dependency on an Apache source tree
(I never rebuild Apache myself).

This looks like another problem that we used to have with PHP3 because
loading of shared libraries was not enabled by default in the PHP3
compilation process... I never ran into that problem myself with PHP4,
but you may want to read the following FAQ and try to make the proposed
change to the LDFLAGS in your PHP4 makefile:
http://mapserver.gis.umn.edu/doc/phpmapscript-install-howto.html#d41e558

There may also be an option in the PHP4 configure to enable dl ... you
should probably look for that first.

country.jpg and country.wld are in the same directory as the shapefiles
<cgi-bin>/../htdocs/demo/data/country.jpg. That seems correct to me,
because when I rename the .wld files so that mapserver can not find them
I get an error message. The error disapears when the names of the .wld files
are correct. Seems mapserver looks for them in the directory I put them.

This may seem to be a silly question but is country.jpg & country.wld in
<cgi-bin>/data/country.jpg or in /temp/country.jpg ?
Unless I'm missing something, I don't see a problem comparing the wld's &
the extent.

Daniel,

Thanks for your response. I have finally discovered that dynamic loading 
of libraries is not supported on PHP on OS X as of yet. Thanks to Steve 
W for pointing the following link to me 
http://developer.apple.com/internet/macosx/php.html

I have updated the wiki appropriately.

Kishor,
The foll. config. should be sufficient:
./configure  --prefix=/rstc/user1/erc/pushkar/php-4.0.6
--with-regex=system --enable-discard-path --enable-dbase

you may need dbase to write dbf files, I think you also better use system
reg. exs. as the inbuilt regexs of php have some problems.

Nicole,

I the tiff being covered up by subsequent layers? Objects are layered
from the top of the map file to the bottom, so object placed in the file
first are under objects later in the file.

Try a simple test. copy the mapfile and remove all the other layers
except the one you are trying to include and see if it shows up.

Test two. with the test mapfile, remove the EXTENTS line so mapserver is
forced to comput the extents for the shape file and then see if it is
visible.

Subject: [mapserver-users] using Mapscript to pan around a querymap
Message-ID: <scc3fe35.080@co5.dnr.state.mn.us>

It is possible with the main CGI mapserver assuming you can to the address lookup. That tends to be a rather sophiticated query (or series of queries) and that's why you would need MapScript. Actually you wouldn't even need MapScript. You could just use a helper program to do the address lookup and then intialize a CGI MapServer session from that output. Attribute queries that start a pan/zoom interface can be done without MapScript, you just need to have a normal pan/zoom interface as a part of your query template. You also might use saved queries to keep a particular feature hi-lighted as you pan/zoom but there are ways around that as well using a dynamic expression.

This feature is not implemented in directly in Mapserver. MapScript has
a queryByAttributes() function that might work, but I am not sure how it
works.

Can someone from DM Solutions comment on this?

I wrote my own GeoCoder in C that works off the shape files but it is
somewhat targeted at US Census data. You can see it at
http://swoodbridge.com/cgi-bin/geo enter and address east of the
Mississippi in the US.

Some other people were working on an OpenSource version - you might want
to check the list archives for more information.

You could build something to do this with shapefiles in Perl or
PHP/Mapscript because both of these can open *.dbf files where all the
attributes are stored and scan the records.

I hope this helps,

For an example of this kind of thing in action, see 
http://office.refractions.net/dra_roads/main.php
The roads live in a PostGIS database, so we do the geocoding against the same 
database as we do the map rendering.

Message-ID: <scc41a07.086@co5.dnr.state.mn.us>

Sure. ! recieved 25 responses everyone of them positive (but not all could attend). Not much from the international group though, which is understandable (unfourtunately). From these messages I would guess about 25-40 people would attend with some of those being students. I don't know if that's large enough a group to warrant a meeting or not. Our mailing list has around 500 members so I guess I'm a bit disappointed in the overall response.

Attendance would definitely be impacted by budget woes around the country/world and cost was a major issue brought up in many of the responders. Note that $300 to $400 was a guess, but unless some form of support could be identified some cost would be incurred since the UMN has no budget to put this on.

Attendance would also be impacted by other events going on in the fall. These were other events in the fall that were mentioned:

  - URISA 10-26 to 10-30
  - ION GPS 9-24 to 9-27
  - MN GIS/LIS 10-2 to 10-4
  - GRASS (Italy) 9-11 to 9-13 

(Wouldn't the GRASS conference be a nice one to piggyback onto.)

In terms of topics, those that commented mentioned 3 primary areas of interest:

  - future development
  - current applications (what are people up to)
  - hands on workshops

With the hands on stuff drawing the most attention. Of course that makes getting a program in place all the more difficult because much more material needs to be developed. On the bright side several folks offered to help.

What next, I don't know. The UMN ultimately will have to make the decision.

What was the result of your inquiry about a MapServer meeting sometime in

Subject: [mapserver-users] dynamic point with reference map
Message-ID: <3CC467D2.CDF5DE9F@keyspanenergy.com>

I'd like to inquire about this functionality on the Image being rendered... not
on any reference map.
I've taken a regular map file and added the same kind of arguments as follows to
the URL, but cannot find any change in the map I've created. I use decimal
degrees, so I chose LAT/LON values that are approximately in the center of the
image. (I switched the order of LAT/LON to see if I was wrong there.)
&map_webuser_feature=new&map_webuser_feature_points=-71.965000+43.254000&map_webuser_feature_text=My+House

&map_webuser_feature=new&map_webuser_feature_points=43.254000+-71.965000&map_webuser_feature_text=My+House

Should the above additions to the URL work?
Here's the full URL, but it's behind our firewall and not accessable on the net.

http://mi.keyspanenergy.com:81/mapserv/mapserv.exe?map=%2Fmaps%2Ftmp%2F1019503669885.map&imgext=-71.969000+43.250000+-71.961000+43.258000&imgbox=5+16+477+492&imgxy=5+16&mode=browse&zoom=1&map_webuser_feature=new&map_webuser_feature_points=43.254000+-71.965000&map_webuser_feature_text=My+House

Thanks for any help.

Message-ID: <scc44119.073@em.agr.ca>

Hi, I'm trying to set up a Mapserver .map file that will make use of the WMS client capabilities, but I'm having difficulty.

I will include my mapfile.  The error I am getting is located in the image area itself and it says: msProcessProjection():no system list, errno: 2

I take this to mean that it is looking for the epsg file, which, on my system, is located in the proj/nad directory where it should be and I have no problems with projections in my other work.

I can also see the layer that I want to connect to if I just type the connection URL into my browser.  Works fine.

If anyone could shed some light on this I'd really appreciate it.
Thanks,
D. Pagurek

Message-ID: <3CC49B2B.78C29787@swoodbridge.com>

Mapserver Documentarians,

Could I get some one to make a minor update to the Utilities doc page at
http://mapserver.gis.umn.edu/utils.html

For the tile4ms utility, please document:

tile4ms -h

usage: tile4ms <meta-file> <tile-file> [-tile-path-only]
<meta-file>     INPUT  file containing list of shapefile names
                (complete paths 255 chars max, no extension)
<tile-file>     OUTPUT shape file of extent rectangles and names
                of tiles in <tile-file>.dbf
-tile-path-only Optional flag.  If specified then only the path to the 
                shape files will be stored in the LOCATION field
                instead of storing the full filename.


The -tile-path-only is missing and even knowing it existed I have to
look at the source to find it. OK, it didn't occur to me to look at the
command line help until after I looked at the source - so call me a
programmer :)

Anyway, it would be a big help, Thanks.

Oh, I will update wiki.

Subject: [mapserver-users] Ack! shptree bug????
Message-ID: <3CC4ACA3.B4187395@swoodbridge.com>

Help Steve, Carl, anyone,

I have run into a bizzare situation that might be a bug (probably mine),
but you never know!

Here is the scenario:

1) I build a tile4ms of my tiger data files.
2) I wrote a C program to read the tileindex and compress the entries so
I only have one entry per directory. (I'll come back to this)
3) I create a shptree of the tileindex.

This was working fine except, I had a minor bug in my utility and did
not write the last directory info to the new tileindex so I had a county
that never showed up on the map. So a add a few lines of code, to add
the last entry before closing the files. Reprocess the tileindex and
create the shptree index and NOTHING shows up on my map!

Comment out the new code and repeat the process and the map works minus
the missing last directory. OK, scrates head, checks the code, the
process, tries again and gets the same results. I check the new
tileindex using shapechk it says it fine and dandy. dbfdump and shpdump
looks great.

Ok, I use the new tileindex but delete the tileindex.qix file and every
thing works great. The map shows up along with the previously missing
county. Make a new shptree index and everything in the tileindex
vanishes again! Seems like a shptree problem. mapserver 3.5 and I do get
an image back with other layers that are not in this tileindex.

Is this the a variation on the hanging bug that a patch was released
for? I will go find patch and try that.

Any other ideas.

I did a shptreevis on the tileindex and got:

shptreevis tgrindex tgrindex-new
This old MSB index supports a shapefile with 524288 shapes, 150994944
depth 

doesn't a depth of 150994944 seem excessive!!!!

And when I try to view the file in ArcExplorer I just get a line across
the image.

That is a possibility, but when I ran shptreevis on the bad index it had
a depth of over 150,000,000 which is a problem. when I ran shptree
tileindex 13 NM I get a good file.

creating index of new MSB format
[woodbri at linus mdata]$ shptreevis tgrindex tgrindex-new
This old LSB index supports a shapefile with 2048 shapes, 13 depth 

This looks more and more like shptree bug. It is possible that I have
created a bad record with my compression utility. I'll check on that,
but if that is the case, it would be nice if shptree did some basic data
checking. 

BTW, the compression utility just reads successive records and
accumulates the extents until the LOCATION field changes and then writes
out the record, clears the accumulators and repeats. At the end of the
file it writes the data in the accumulators as the final record and that
record is good data. Could it be that I have exactly 2048 records which
is a power of 2?

Stephen,

Are you working with a recent MapServer and tools from CVS?  There was a
bug related to correctly determining the byte order of "old native format"
quadtrees that was fixed Jan 22 in maptree.c version 1.8.  If you don't have
that 1 in 256 old style quadtree indexes will be read as "corrupt" because
of a mistake in guessing the byte order.  The problem is not encountered
in the new format indexes and is fixed in CVS.

Best regards,

Subject: [mapserver-users] Problem installing PHP Mapscript
Message-ID: <OF4ED19299.EED4D649-ONC1256BA4.0022F409@rohoel.at>


I'm having a problem installing PHP/MapScript. As I have a third party
hosting my site, I have been forced to use the workaround which involves
configuring a copy of the PHP source before compiling mapscript. Everything
seems to go OK. I have a working mapserv executable, and I get a
php_mapscript.so.

However, when I place php_mapscript.so in my extensions directory and do a
phpinfo() from a test page, I get the following error:

Warning: Unable to load dynamic library
'/usr/local/lib/php/20010901/php_mapscript.so' -
/usr/local/lib/php/20010901/php_mapscript.so: Undefined symbol
"PQconnectdb" in /usr/local/etc/httpd/htdocs/test.php3 on line 11

I searched the archives and found one other occurrence of this problem, but
no follow up messages. Anyone have a clue as to what is wrong here?

My PHP config and Mapserver config parameters are below, in case they shed
any light on the situation:

PHP Config:
?./configure --enable-inline-optimization --with-

Thanks in advance for any help. I'm stumped.

Marc,
I just ran into a very similar problem myself.  Except that in the
folloowing:
Undefined symbol "PQconnectdb" in /usr/local/etc/httpd/htdocs/test.php3
on line 11

I had:
Undefined symbol "ShowError .... " in
/usr/local/etc/httpd/htdocs/test.php3 on line 11


This was caused by the fact that I had to compile PHP as a CGI, but my
mapscript compile was done with the following option (in addition tothe
--with-php and a couple others):
--with-apxs

Removing "--with-apxs" cured my problem.

Hope this helps,

Rob

Hi Debbie,

The error seems to come from the tsadev.speciesanalyst.net server that
you are cascading... it probably doesn't have an "epsg" file (or it's
not found by mapserv.exe).  See what you get when you connect to the
server directly and specify an EPSG SRS:

}
 
$layer_dash = $map->getLayerByName("dash");   <---- here

Marie-christine,

Non l'object QUERY n'est plus utilis?.  Tu doit tout simplement definir un
TEMPLATE dans ton LAYER, le reste est fait dans le template en tant que tel.

Exemple:

LAYER
  NAME park_p1649
  GROUP base
  TYPE POLYGON
  STATUS DEFAULT
  DATA park_p
  MINSCALE 1398433.17556762   
  MAXSCALE 10488257.3167571   
  CLASSITEM "AREA"
  METADATA
    "lay_title" "National Parks"
    "checkable" "0"
    "query_attributes" "AREA_KMSQ; NAME; YEAR_EST"
    "legend_order" "2"
  END
  CLASS
    NAME "Park Area"
    OUTLINECOLOR 0 153 0
    SYMBOL 0
    COLOR 0 153 0
  END
  TOLERANCEUNITS pixels
  TOLERANCE 9
  TEMPLATE /home/mapdata/aoc_v3/queries/park_p1649.html

Message-ID: <200204231811.OAA20670@www21.ureach.com>

Dear Mapserver Users!

1. Thanks in advance for help and suggestions. I need to 
dynamically turn labels on/off the map when 
certain events happen (attributes are changed in dbf file). 
I set the colors dynamically already (I introduced an extra 
field in dbf file 
and use expression statement to change the color ) 

Can I use the same EXPRESSION statements to turn the labels 
on/off based on certain dbf fields values?  

Do the labels scale in size when the map is scaled ? Do I need 
php/mapscript or I can use straight CGI module ?


 Any pointers to examples are appreciated.


2. Also any chance to prezoom the image when displaying it the 
first time (appear too small and 
changing the extent parameters does not do much )


Thanks again

I have the getlayersdrawingorder function working without drama, but get the following error when I use the setlayersdrawingorder function using MapServer 3.5 and PHP 4.06.
Call to undefined function: setlayersdrawingorder() in /var/www/mapserv/test.php

My code is as follows:
$layerord = array();
$layerord = $map->getlayersdrawingorder();
$success = $map->setlayersdrawingorder($layerord);

I'm not bothering with actually changing the layer order until I can get this going. 
Any advice or help on this issue would be appreciated.

Message-ID: <001101c1eb63$d1879d60$0601a8c0@comai.loc>

Hi,

I have tryed the GMAP example with Rosa Applet and all works correctly. Then
I have inserted my new layers in the map file and obviuosly I have changed
the extend.

Now, the *first time* that I try to do a ZOOM IN operation, this operation
"fail". In other words the first ZOOM IN operation zooms in a wrong area
(zooms near the area that I have selected but not exactly in this area).

The following Zoom In operations work correctly.

Can Someone help me?

PS: I have only inserted my new layer and changed some parameters in the map
file!

Thanks,

Stefano B.

Hello everybody!
 Seems something was misunderstood.
 I want to enter a point attribute (no geocoding), have the map zoom to the corresponding point
, then to pan around this location, using the same template (map).
I want to locate a feature whose attributes matches my search criteria, attributes which exists in shape database, zoom to the corresponding point, then pan arround.
Querymap is a good mechanism, but I need to know somehow, the extent of querymap to transfer these coordinates to a regular map.

The roads live in a PostGIS database, so we do the geocoding against the same 
database as we do the map rendering.

Hi,

Mapscript is installed on my computer. ( Linux suse 7.2 Mapserver 3.5)
./mapserver -v -> Mapserver verion 3.5 OUTPUT=PNG OUTPUT=JPEG
OUTPUT=WBMP SUPPORTS=PROJ SUPPORTS=TTF INPUT=TIFF INPUT=EPPL7 INPUT=JPEG
INPUT=GDAL INPUT=SHAPEFILE
As you can see proj is installed.

When I put phpinfo(); in a php page I get:
MapScript Version (Nov 27, 2001)
MapServer version 3.5 OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP SUPPORTS=TTF
INPUT=TIFF INPUT=EPPL7 INPUT=JPEG INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE
As you can see proj is not installed !!!

What am I missing ?
Why proj support is not include in my phpinfo() result ?

Thanks

Stuart,

By looking at the CVS logs, it seems that setLayersDrawingOrder() was
added on 2002-01-17, which is after the 3.5 release.  I can't explain
why it wasn't added at the same time as getLayersDrawingOrder(), but it
seems that you'll have to upgrade to the 3.6 development version if you
want to use it.

Stephane,

You seem to be missing OGR support as well (in addition to PROJ) in your
PHP Mapscript... I suspect that you are either pointing to the wrong
copy of php_mapscript.so, of your build environment got screwed up
somehow.

I suggest that you first delete php_mapscript.so from your
extension_dir, and try running your test script again to verify that PHP
will complain about php_mapscript.so not being found... if you don't get
an error then the problem is likely that you have two copies of
php_mapscript.so around... you should fix that problem first.

Then reconfigure mapserver, and 'make clean ; make' ... and then
reinstall php_mapscript.so

Daniel

Stef,

Did you do a make install from the mapserver build environment?
Check and see if you have a /usr/local/lib/libmap.a and delete it if you
do. Do NOT do a make install! If it was there, do a make clean; make and
try again.

Also check that all of your libraries are accessable at runtime with
/sbin/ldconfig -pX and make sure the proj and GDAL libraries if listed
in the ldd command also so up on this list.

If they don't then you need to make sure the /usr/local/lib is included
in /etc/ld.so.conf and run /sbin/ldconfig as root.

Hi,

I've been trying to store a complete mapObject in the session vars in php.
Every time I try to perform a task on the unserialized object I get

Fatal error: Object has an invalid _handle_ property in ....

Also a complete serialized mapObject of 40 layers looks something like the
stuff you see below, while one serialized layerObject allready looks like

O:5:"layer":33:{s:8:"_handle_";i:0;s:12:"_map_handle_";i:0;s:10:"numclasses"

Seems like something's going wrong.

I use mapserver 3.5 an PHP 4.0.6 and hope someone can help me.

does case matter? is setLayersDrawingOrder different from 
setlayersdrawingorder?

I have been noticing several such variations in the docs, and am not 
sure if they are intentional or a mistake. I have flagged the ones I 
have come across, and will send them to Jamie (or whoever is in charge 
of the docs). There are also a few (very few) spelling errors in the 
docs.

If the case does matter, would it be possible to bring all the methods 
to conform to one convention? perhaps  'all lower case' is better than 
'mixed case' because then we don't have to guess which it is?

Many thanks,

Vincent,

You cannot serialize a mapObj or any PHP MapScript object... this is
because those objects are not pure PHP objects, they are really just
wrappers on top of the MapServer C data structures, and PHP serializes
only the PHP wrapper but not the underlying C objects... that's why you
get this error.

So you'll have to either reload the original map using ms_newMapObj() in
every request and reapply your changes to the mapObj in every request,
or if the number of changes is very large and this is not an option,
then you can save the mapObj to a temporary file using
$map->save("/tmp/tmp123.map"), and store the temp filename in your
session variables and reload the temp mapfile at the beginning of the
next request.

In PHP, function names are case-insensitive, but variable names are
case-sensitive.

That's why in the docs you'll notice that we use mixed cases for method
names, but someone could really use all uppercase or all lowercase and
the function calls would still work.  OTOH, for class member variables
we always use all-lowercase since they are case-sensitive.

Now, it is quite possible that the PHP MapScript docs could contain some
errors or typos, so if you noticed errors in the PHP MapScript docs then
please file them in bugzilla, under the PHP MapScript component and
we'll fix them.

Here's how I configured:
./configure --with-ogr=../gdal-1.1.7/ogr

Hi Jeff,

Under your Layer definition in the Map file try the following:

LAYER
  NAME quads
  DATA "D:\gisdata\quads"
  STATUS DEFAULT
  TYPE POLYGON
  CLASS
    NAME "100K Quads"
    OUTLINECOLOR 0 0 0  # black outline
    # COLOR 225 225 185 (here the fill color is commented out)
    END
  END
END

... Instead of using a fill color and outline color like the following:

CLASS
    NAME "100K Quads"
    OUTLINECOLOR 0 0 0
    COLOR 225 225 185
    END

Did you check your server error log?  Let us know what it says.  I'm
interested in this, because I'm also getting a 500 Internal Server Error.
Apparently I compiled something against two different versions of libpng,
and I'm getting an error because of it.  Here's my error.log entry:

============================================================
libpng warning: Application was compiled with png.h from libpng-1.0.12
libpng warning: Application  is  running with png.c from libpng-1.2.2
gd-png:  fatal libpng error: Incompatible libpng version in application and
library
============================================================

Can anyone tell me which application(s) this error is referring to?  I
thought it was gd, so I recompiled gd making sure to reference just the
newer version of libpng, but that didn't help.  I did the same thing with
MapServer, to no avail.  This error is thrown when trying to load the Itasca
demo.

Thanks.

I would like to open query results in a new browser window.  Can I do this
in the map file somewhere, say by pointing a query reference to _blank or
something like that? Any help would be appreciated.

Thanks a lot Daniel,
 you were right I have two copies of php_mapscript.so.
Now it works perfectly.
Could tell me where I can find documentations or examples on how to use
proj4 ?

Thanks

Subject: [mapserver-users] Online Geocoding?
Message-ID: <015901c1ec80$0d223840$0300a8c0@p200>

Does anyone know of an online geo-coding service.

i.e. they have an address form press submit and back comes the geo-code.

I may process 10-1000 GeoCodes a day and need it in realtime.  I've scene some sites that allow you to do 100 free geo-codes, but would like to use a subscription type service.

I am planning to write a script that connects to their web page, posts the data to a form, captures the returned geo-code and then update my database record.  Another wonderful job for PERL.

Thanks
Steve Lehr

For those of you have not done such a thing-- here a nifty script that POSTS/GETS data from a web form.

#!/usr/bin/perl -w
use Socket;
use strict;
# these are the only pertinent variables
my $ip ="www.wherver.com";
my $path = "geocode.pl";
my $content = "CMD=geoCode&Address=123+Seaseme+St&";

my ($sec, $min, $hour, $mday, $mon, $year, $wday, $yday, $isdst) = localtime(tim
e);
my $timestr = sprintf("%4d%02d%02d%02d%02d", $year+1900, $mon+1, $mday, $hour, $
min); 
my $host = $ip;
my $port = 80;
my $socketaddr;

print HTML "\nRetrieving page $path with $content";

print "\nRetrieving page $path with $content";
openSock();
post ($content);
@wholePage = <SOCK>;
close SOCK;
print HTML @wholePage;

exit;

###########
# subroutine: open a socket at SOCK
###########

sub openSock {
$socketaddr= sockaddr_in $port, inet_aton $host or die "Bad hostname\n";  
#print "Connecting to $socketaddr $host, $port";
socket SOCK, PF_INET, SOCK_STREAM, getprotobyname('tcp') or die "Bad socket\n";
connect SOCK, $socketaddr or die "Bad connection\n";
select((select(SOCK), $| = 1)[0]);
}


###########
# subroutine: send post request to target web site
###########

sub post {
my $content = shift @_;
print SOCK "POST http://$host/$path HTTP/1.0\n";
print SOCK "Content-type: application/x-www-form-urlencoded\n";
my $contentLength = length $content;
print SOCK "Content-length: $contentLength\n";

}

Subject: [mapserver-users] drawing acetate shapes with PHP/Mapscript
Message-ID: <A0E513A7DCA9C24F933204619CEBB3D36FFD@email.geoanalytics.com>

once a map is drawn, I'd like to add a triangle, a circle, or a square, or
whatever... (but, let's take the example of a triangle for now) on top of
everything.

the way I understand it, I would have to --

1. have an "acetate" layer with 'STATUS off' in my map file like so...

LAYER
  NAME "acetate"
  TYPE polygon
  STATUS off
  CLASS
    OUTLINECOLOR 255 0 0                        # red outline
    COLOR 0 255 0                               # green fill
  END
END

2. and use Mapscript like so...

$layerObj = $mapObj->getlayerbyname("acetate"); // new layerObj

sorry,

instead of

I intended

> $imgObj = $mapObj->prepareImage();              // imgObj




any advice on this would be much appreciated.

Thanks.

ok... I figured it out... the code below works for drawing a triangle on an
"acetate" layer...

questions...

1. this worked for me...

$lineObj1->addXY($x1, $y1);

But this did not...

$pointObj1 = setXY($x1, $y1);
$lineObj1->add($pointObj1);


why not?

2. How do I draw a circle around a given point?


free beer at the mapserver users meeting in the twin cities (if and when it
happens) to the first person who answers this. my eyes are hurting.


tia,

pk/








 1. have an "acetate" layer with 'STATUS off' in my map file like so...
 
LAYER
   NAME "acetate"
   TYPE polygon
   STATUS off
   CLASS
     OUTLINECOLOR 255 0 0                        # red outline
     COLOR 0 255 0                               # green fill
   END
END

2. and use Mapscript like so...
 
$x1 = 250; $y1 = 250;
$x2 = $x1 + 5000; $y2 = $y1 + 7000;
$x3 = $x1 + 3000; $y3 = $y1;
$x4 = $x1; $y4 = $y1;

$layerObj = $mapObj->getlayerbyname("acetate");
$classObj = $layerObj->getClass(0);
$imgObj = $mapObj->prepareImage();
$shpObj = ms_newShapeObj(2);

$lineObj1 = ms_newLineObj();
$lineObj1->addXY($x1, $y1);
$lineObj1->addXY($x2, $y2);
$lineObj1->addXY($x2, $y2);
$lineObj1->addXY($x3, $y3);
$lineObj1->addXY($x3, $y3);
$lineObj1->addXY($x4, $y4);
$shpObj->add($lineObj1);

$shpObj->draw($mapObj, $layerObj, $imgObj, 0, "foo");
$acUrl = $imgObj->saveWebImage(MS_PNG, 0, 0, -1);
$layerObj->set("status", 1);
$lineObj1->free();
$imgObj->free();
$shpObj->free();

one more... drawing a circle at origin x0, y0, with radius r

the following code works for me...

==========

$x0 = 250; $y0 = 250; $r = 5000;

[.. create various objects ..]

for($y = -$r; $y < $r; $y++) {
  $x = sqrt(($r*$r) - ($y*$y));
  $xtemp = $x0 + $x; $ytemp = $y0 + $y;
  $lineObj->addXY($xtemp, $ytemp);
}

for($y = -$r; $y < $r; $y++) {
  $x = sqrt(($r*$r) - ($y*$y));
  $xtemp = $x0 - $x; $ytemp = $y0 - $y;
  $lineObj->addXY($xtemp, $ytemp);
}

$shpObj->add($lineObj);

==========


surely, there has to be some better way than this kludge.

Subject: [mapserver-users] can't display TIFFs
Message-ID: <002301c1ece0$4712fa20$0a00a8c0@vulture>

I can't seem to get TIFFs to display using MapServer...I get either a blank
page or a "server not found" error.  I'm using a modified version of the
Europe PHP example (nothing fancy), and I can display shapfiles just fine,
unless the raster layer is included in the mapfile.  If I comment out that
raster layer, everything displays fine once again.

I've tried three different TIFFs, with no luck.  All TIFFs are in the
correct projection & datum, are 8 bit images, and display fine with the
associated shapefiles in other applications.  The TIFFs were created using
the GRIDIMAGE command in ArcInfo, and I renamed the .tfw extension to .wld
(tried it both ways, actually).  And it's not a permissions problem.  I've
tried both colormap and grayscale images, with no difference.  I followed
the "Raster HOWTO" instructions, and the "Converting ArcINFO Grids to
Mapserver TIFFs" instructions in the Wiki, but neither helped.  Am I missing
a format from GDAL or something? (see below).  I compiled
Mapserver --without-tiff.

Thanks for any help, not sure what to try next.

You make only a one-point line object for each line. Try to change the
script as follows:

 $figura = ms_newShapeObj(MS_SHAPE_LINE);  <-- shape type LINE
 $ponto_obj = ms_newLineObj();    <- object line
 for($i=0;$i<$N;$i++){
     $ponto_obj->add($ponto[$i]);  <- get the point
 }
 $figura->add($ponto_obj); <- put in the shape
 $layer = $map->getLayerByName("dash");   <- get the layer to put shape
 $layer->addFeature($figura); <- put shape in layer

Hi,

I have a simple question about DM Solution Group GMap application.

In the gmap75.map file there is a line like this

TEMPLATE "ttt_query.html"

what is this template.

I don't find it in the application files. Where is it?

Thanks.

Subject: [mapserver-users] Street Searching
Message-ID: <014301c1ed11$d85bb400$0601a8c0@comai.loc>

Hi,

I have to develop a Street Searching function where

the user can insert City and Street ( and number) and the application must
display the map centered on this street.

How can I do that with mapserver?
Can you give me an Hint in order to do this.

I read the PHP Map/documentation but I did't find any query of this type.
My personal solution is the following:

with a PHP application I get the user input (Street and City) and I query to
the database in order to find the object ID, then, I "say" to mapserver to
create a map with this object ....

Someone can say me if this is a possible solution or if there are a more
simple solution?

Thanks.

Stefano B.

Stefano,

You have to ahve a TEMPLATE line if you want to do a query on that layer
or the layer will be ignored by mapserver. It is just a dummy file that
does not exist. I use TEMPLATE "void" in my mapfiles to make this a
little clearer.

Stefano,

I wrote a separate CGI program to do this. You could write it in C or
Perl or whatever. It does the address lookup by scanning the approprate
shape files and when it has a result it sends a client redirect to the
browser to get it to load the map with the Lat/Long result for the
search results.

I think you will find this much easier to do if you think about doing it
outside of mapserver/mapscript and only send the final result to get
mapserver to display the answer.

Good idea.  I guess it would be even easier to do just using a query to a

Stefano,

I wrote a separate CGI program to do this. You could write it in C or
Perl or whatever. It does the address lookup by scanning the approprate
shape files and when it has a result it sends a client redirect to the
browser to get it to load the map with the Lat/Long result for the
search results.

I think you will find this much easier to do if you think about doing it
outside of mapserver/mapscript and only send the final result to get
mapserver to display the answer.

Puneet,

I think you're close.  You'll at least need to add "TRANSFORM FALSE" in
your layer definition since your shape is defined in pixel coordinates,
and add a call to $shpObj->add($lineObj) before calling draw(),
otherwise you are drawing a empty shape.

Check if your GDAL was compiled with TIFF support:
gdal-config --formats
gtiff should be there, if it's not then you have to install libtiffs on
your system or configure gdal to use the internal tiff support:

Subject: [mapserver-users] background map image
Message-ID: <20020426165117.GA28461@extempore.otsys.com>

In an attempt to speed up map rendering for our site we opted to build a
set of tiles for the static elements of the data (streets, cities,
water) which would serve as background images for more frequently
updated data.  The dhtml route of creating a transparent PNG file to
overlay on top of the map fails for Netscape4.* which apparently has
poor support for transparent PNG files.

The next choice would be to use other means to combine the images before
they leave the server.  Is there a method for creating a map with
another image as its background using mapserver?  Would this be better 
accomplished using GD.pm?

This is a basic feature of mapserver just use it. See

Hi,
In my maps I want to do the foll.:
The user should be able to select the layers to display and change the
order of the drawing.
I think the fastest way is to do this using javascript, since it runs on
client side it will be fast.
So is it possible to pass an array containing the names of the layers from
php to javascript, after changing the element positions in JS have it back
in php? Some code snippets would also be appreciated. Thanks,

-Pushkar S. Pradhan

Pushkar,

Your php writes the page that is sent to the browser (or can write it)
so just have your php output code to load a javascript array with
values. let the user play with the values and when you are ready to
refresh the display using the new values have your javascript assign the
values to hidden form fields and post the form back to php with the
submit button. You can use an onSubmit() javascript function to trap the
users refresh click and then update the form fields

OK, does anyone know how queryByAttribute() is supposed to be used?

I put my guess below, but I haven't tried it, and Stefano has been
trying to get an answer on this for a few days without much success.

Steve's point about setting the map extent for the area you want to search is a valid and useful one.

For the actual querying, try something like:

$layer->{status} = $mapscript::MS_ON; # if it's not on already
$class = new classObj($layer);        # if you don't have one already
$layer->{template} = $template;       # if you don't have one (or a class template) already
$layer->{filteritem} = "SOMEITEM";
$layer->setFilter("\"$var\"");        # Assuming you're matching on a string
$rv = $layer->queryByAttributes($map, $mapscript::MS_MULTIPLE);    # or MS_SINGLE
$rv == $mapscript::MS_SUCCESS or warn "No match found";

then get your results like:

for ($i=0; $i<$layer->{resultcache}->{numresults}; $i++) {
    $result = $layer->getResult($i);
    ... (do something with the result)
}

See also:

for some hints on how to use queryByAttributes with logical expressions.

If it is actually an image layer you should be able to use the offsite member/parameter to have mapserver merge the layers and assign the transparent color accordingly.

(sorry, I just ate baklava at Husnu's)


your php code automatically gets $arLayers with the checked layers as its
elements that you can loop through.

have fun.

That's exactly what I did for the digital regional atlas munich.  I
have all my adresses with their x/y coordinates as well es the streets
in a mysql table which I query (staged: first street, then address)
and then I return a link to the map.

For performance reason I do this in mod_perl.

Puneet, Steve Thanks for your responses.
I actually achieved the desired in php itself:
I've a checkbox asking whether the user wants to change the drawing order
of layers,
if it's checked it redirects them to a new page with the chosen layers,
the user plays around with this array (arranging elements) and when they
submit they are redirected to the original page,
then I plan to do setlayers....() etc.
I suppose lot of people must have done this, actually I have to do this
since one of our client wanted to specify his own drawing order?

Subject: [mapserver-users] can't display TIFFs
References: <Pine.GSO.4.44.0204261144310.9635-100000@Titan.ERC.MsState.Edu>
Message-ID: <001301c1ed7a$d75ace10$4622c180@widberry>

I fixed the problem.  Thanks to Frank, Pushkar, and Tyler for their help.
gdalinfo and my server log both indicated a segmentation fault when I tried
to display tiffs in my application.  The problem was that gdal was not
functioning correctly...either libtiff or libgeotiff was not behaving within
gdal.

When I first implemented gdal I tried compiling with the latest versions of
libtiff and libgeotiff (not using gdal's internal support).  I couldn't get
it to accept that version of libtiff when compiling, so I configured gdal
with:

  --with-libtiff=internal
  --with-libgeotiff=/usr/local/src/libgeotiff-1.1.4

This gave no errors during compilation, but did not allow gdal to function
correctly (resulting in the segmentation errors I've been getting).  Frank
recommended compiling gdal with internal libtiff AND internal libgeotiff
support, which is the safest approach.  However, by that time I had already
tried once again to compile with both newer versions...

  --with-libtiff=/usr/local/src/tiff-v3.5.7
  --with-libgeotiff=/usr/local/src/libgeotiff-1.1.4

...and this is now working fine!  I can display rasters to my heart's
content :-)  I don't know why gdal accepted these configure parameters this
particular time, after I had tried seemingly hundreds of other times (ok,
maybe 10 times :-)  The only thing I did differently was change the order of
options in my ./configure statement, but I don't know why that would make
any difference.

Anyway, thanks to all for the help.  I've been having a lot of fun
experimenting with OFFSITE.

I rebuilt Mapserver and mapsript. The stock examples (shpinfo.pl and

I am trying out the simplest of code (after sdl's mapquakes.pl)...

1: my $rootdir = "/Users/pkishor/Sites/ms";
2: my $imgdir = "/$rootdir/tmp/";
3: my $imgurl = "/~pkishor/ms/tmp/";
4: my $map = "/$rootdir/map/my.map";
5: my $imgid = $$ . time() . ".png";
6: my $mapobj = new mapObj("$map");
7: my $img = $mapobj->prepareImage();
8: mapscript::msSaveImage($img,
                        $imgdir . $imgid,
                        $mapobj->{imagetype},

                        $mapobj->{imagequality});

I get the following error... obviously prepareImage is failing because 
$mapobj can't be created on line 6 to begin with. What is causing the 
following "Uncaught exception..."

OK, I been lurking on this question, nd I really want to know some of the secrets too. I got as far as
getting the result as indicated below (although I am using PHP mapscript), but it is the "do something
with result" part which has me stumped. I can not get any action out of any of the variables listed in
the php mapscript documentation for result, and trying to fetch each of the results by using
$thisresult->next() gives me an "Fatal error:  Call to undefined function:  next()" error.

basically, I am trying to iterate through each shape in a given layer, and do such things as query for
adjacent neighbors, in the fashion of a neighborhood function. Any help would be appreciated. By the way,
my query .numresult gives me the number of shapes int eh layer, which makes me think things are going OK
till then. Code is as follows:

$lq = $thislayer->queryByAttributes(MS_MULTIPLE);
          $ni = $thislayer->getNumResults();
          $res = $thislayer->getResult($lq);
          $rsi = $res->numresults;
          $rti = $res->numquerylayers;
          $restr = $res->next();

Subject: [mapserver-users] Perl Mapscript -- CALL FOR EXAMPLES
Message-ID: <3CCB0787.2BDB2354@swoodbridge.com>

I has come to my attention because a feww people have asked me off list
(and since I went looking and could not find any good examples) that we
have a lack of examples Perl Mapscript!

SOoooo, this is a   CALL  FOR  EXAMPLES.

The goal here is to get a broad set of samples that will help people
getting started with Perl/Mapscript have a resource to look at and get
them jump started.

I would like anyone that has working examples of Perl/Mapscript, that
would like to post them as examples for the fame, fortune and maybe
infamy :) to:

1) post them on wiki at
http://mapserver.gis.umn.edu/cgi-bin/wiki.pl?PerlMapScriptExamples35
with a description, your contact info, a link to a working version if it
is available somewhere.

-- OR --

2) email the same to me and I will be happy to add them to wiki if I
don't get swampped with them :)

This would be a good place for all levels of scripts from simple tools
to full blown user interfaces like GMap75 is for PHP, examples of
serving maps, map navigation, working with rasters, dynamic adding of
points, lines, gps data, whatever or working with shapefiles, or
database integration. Show us what you have been doing!

If you have zips or tarballs I will try to get them loaded on mapserver
also, provided sysadmins will support it.


PLEASE DO NOT SEND me stuff that you do not have a right to post or
offer to the public in general.

Many thanks,
  -Steve Woodbridge

ok... I have spent a good part of today battling this, and have 
discovered the following...

one of the reasons I am getting these errors because I have -w switch on 
my shebang line. After much finagling, I can get the image to draw, but 
with the -w switch I get the following error as well --

(in cleanup) Not a HASH reference at /Library/Perl/darwin/mapscript.pm 
line 1468.

that line in mapscript.pm is the one that is trying to clean up... and 
failing. Specifically,

sub DESTROY {
     my $self = tied(%{$_[0]});
     delete $ITERATORS{$self};
     if (exists $OWNER{$self}) {
         mapscriptc::delete_mapObj($self);
         delete $OWNER{$self};
     }
}

perhaps Lowell or Steves (L* and W*) shed some light on this.

Many thanks,

Steve said "Wouldn't the GRASS conference be a nice one to piggyback onto". 
Actually the GRASS conference in Italy plans to have at least some 
mapserver content. The conference is called "Open source GIS - GRASS users 
conference 2002" and the conference web site is:
http://www.ing.unitn.it/~grass/
And I first heard mention of the conference on this list, I think in a post 
by Paul Ramsey.

I submitted an abstract to do a mapserver presentation. Is anyone else going?

I've the same problem!
It is not a warning but a fatal error for perl.

The problem, i guess, is related to the use of tied hash to support
mapscript objects ... 

I've added a PRINT ...

sub DESTROY {
    print STDERR "!!!! Destroing $_[0] ...\n";
    my $self = tied(%{$_[0]});
    ...

The DESTRUCTOR is called two times! The first one with $_[0] that is a
reference to an hash, the second to a scalar so function "tied" raises
the error!

!!!! Destroing layerObj=HASH(0x83e925c) ...
!!!! Destroing layerObj=SCALAR(0x83d8ef4) ...

Empirically i've seen that, if I undef the variable containing the
reference to the object before returning from the sub where i use it,
than the error disappears ... (also if the two call to the DESTRUCTOR
are always there, but probably the undef value is passed)


We need a PERL guru ...!

thanks for analysis Giorgio... I will try out some of your shenanigans 
detailed here...

since it has not been reported exhaustively, I guess there is something 
about our implementation that is bringing this out. My guess is so... if 
there is an error in the Perl script (because of our own programming 
mistake), the script goes kablooie and the map object vanishes without a 
warning. However, the coded garbage collector tries to clean it up, 
except it doesn't find anything. So, it croaks.

I think we already have a few on this list, probably starting with Steve 
Lime at the very top considering he wrote most of this wizardry to begin 
with... I am sure between him and Steve W and Lowell and Paul Ramsey, 
etc., we will be able to squash this.

 Hello,
I am trying to retrieve and work on a shape from a layer (see code below
and map files snippet). All works well with my map, including showing
the map, and verifying that I can grab layers objects, etc. When I try
to retrieve a shape from a layer though, my script dies without warning.
I know that the layer 'microhup' exists in my map, and I know that it
has 125 data lines, which I assume are shapes (microhup is an esri
polygon shape file, with all of its subordinate files, .dbf, .shx,
etc.), and I also know that the column "ID" exists in this file. In the
code below, I have queried for record 1 (see getShape(-1,1), it is an
untiled layer), to see if I can view its props. Can anyone tell me what
I am missing, or point me to something which might explain teh process
of retrieving individual shapes from a layer?

<start php mapscript snippet.... >
     $map = ms_newMapObj($map_path.$map_file);

       $data = $thislayer->data;
       $res = $thislayer->getShape(-1,1);
       $reso = $res->type;
       $resi = $res->values["ID"];

Robert,

I tried your script and couldn't produce a crash.  All I got was an
"invalid shape id" error from the getShape() call which was due to the
fact that the layer was not opened before the call to getShape()... I
added a call to $thislayer->open($map->shapepath); before the getShape()
call, and the script works fine for me.

I tested this on Linux with the MapServer CVS source from end of last
week.  Which version of MapServer are you using and on which OS?

Daniel

I don't think that the binary with the GDAL option includes ECW support. I 
have a binary at www.greenwoodmap.com/mapserver that you are welcome to 
use. The zip file also includes some ER Mapper dll's that should be placed 
in your \winnt\system32 directory.

Subject: [mapserver-users] queryByAttribute()
Message-ID: <200204291523.g3TFNHG16364@philbert.dnr.state.mn.us>


I do these things in Perl, but I think for the most part the PHP setup parallels the Perl setup.  That 
said, it looks to me like the PHP docs are missing a ResultCacheObj Class, which belongs to a layer and 
holds the results of a query on that layer.  

Also note that queryByAttributes (or any of the queryBy methods for that matter) returns success or 
failure, not an index variable.  

So generally, in Perl, you might say something like:

$return_value = $thislayer->queryByAttributes($map, $mapscript::MS_MULTIPLE);
if ($return_value == $mapscript::MS_SUCCESS) {
  for ($i=0; $i<$thislayer->{resultcache}->{numresults); $i++) {
  # resultcache is member of layer, numresults is member of resultcache
    $result = $thislayer->getResult($i);
    $rv = $thislayer->getShape($shape, $result->{tileindex}, $result->{shapeindex});
    # Now do something with the shape...
  }
} else {
  warn "Nothing Found.";
}

Hope this helps,

A quick question.  I think I already know the answer, but here goes....

Is it possible to have a multi-colored dashed line?  Such as a road that is  red-black-red-black, etc.??

Any gurus feel free to step forward, in the mean-time I have a couple of questions:
Puneet - is "(in cleanup) Not a HASH reference at /Library/Perl/darwin/mapscript.pm ine 1468." the ONLY error message in your log? Are there ANY other messages in the log around the same time (within a second or so)?
Giorgio - which DESTROY subroutine did you insert your print statement into, mapObj, layerObj, classObj, ...? It looks like layerObj as opposed to mapObj where Puneet is having trouble.

Hi Lowell,

My problem is specifically in mapObj... the DESTROY sub in the mapObj. The
error message you refer to is the only error message.

You asked for my map file... I can send you the file, but it is really a
very simple map file. The problem is not with that... the problem is with
some error trapping... I have got my perl code/map file/data combo working
now. However, if something goes wrong in my code, this error crops up.

here is what I have gathered...

if I make some mistake in my coding, mapscript.pm is unable to recover from
it... in other words, while the actual error is not in the mapscript.pm
code, it is the mapscript.pm code that croaks because the mapObj that it is
trying to DESTROY doesn't exist anymore.

Btw, this is not necessarily a mapscript.pm specific thing... that is, there
are others who have experienced such an error with other scripts. This is
also not an OS specific thing... I posted an inquiry about "bus error" on
perl at macosx and a few there have seen this crop up here and there. But, note
that Giorgio also experienced this error... I am assuming he is not using OS
X.

In other words, there is some assertion checking or error-trapping that can
be implemented in mapscript.pm which will cause DESTROY to not fail if the
object it is trying to destroy (in this case, mapObj) doesn't exist. This
way mapscript.pm can fail gracefully, and not cause a fatal error for Perl
altogether.

Thanks,

pk/

Subject: [mapserver-users] zooming to a point with itemquerymap
Message-ID: <8879CCE0F0187742B7302A93A8B87B09029962@mpls.houstoneng.com>

Hi MapServer Users,

 

I am trying to embed a mapserver generated image inside an ASP page and
am having some problems.  I don't even know if this is possible, but
here it goes.

 

I am trying to use the itemquerymap mode to produce a map of the
selected point.  I can get a map zoomed to the full extent of my map
file, but I can not get a map zoomed in on the point.

 

Here is the image tag inside the asp page.  This produces a map at full
extent.

<img
src="/mapserv35/cgi-bin/mapserv.exe?map=sitemap.map&mode=itemquerymap&la
yers=&qlayer=wqsites4-25-02&map_wqsites4-25-02_filter=%22<%=rsSiteMap("s
iteid")%>%22&item=SITEID&value=<%=rsSiteMap("siteid")%>">

 

 

As soon as I put parameters in to zoom to the point, I get an error. 

<img
src="/mapserv35/cgi-bin/mapserv.exe?map=sitemap.map&mode=itemquerymap&la
yers=&qlayer=wqsites4-25-02&map_wqsites4-25-02_filter=%22<%=rsSiteMap("s
iteid")%>%22&item=SITEID&value=<%=rsSiteMap("siteid")%>&mapxy=[shpmid]&b
uffer=50000">

 

 I believe the reason why it does not work is because MapServer isn't
replacing [shpmid] with it's value.  I think this is a limitation of the
itemquerymap or I am simply using it wrong.  Has anyone done a similar
thing using only Mapserv CGI not mapscript?  Are there other modes I
could use to produce the same map?

 

Thanks,

Brian

I believe I have the full picture now. Here is what I'm looking at:
The initial error is not in mapscript.pm but results in a fatal error because the type being sent back to DESTROY is a scalar instead of a hash and perl proceeds to try to handle it as a hash. I think the real problem is why did a scalar come back. Is it because of a misfire in mapscript_wrap.c via SWIG? I don't believe anything should return a scalar because the objects are built as hashes from the start.

hello there im gerald, i dont know who's gonna read
this mail but anyway hope u can help me with my
problem

im in a local GIS company here in the philippines, i
have a project about web based gis and mapserver
answer that problem of me in uploading ESRI's .shp
files to the Internet, 

in using arcview, we can connect a separate .dbf file
to the shapefile using join command, is there any
possiblity that this would also work in Mapserver.
i am plannig to use PostGres SQL as my database holder

how would i possibly do that?

if is sounds complicated then u can first help me with
connecting it to a simple .DBF file using ODBC if
possible.

i am using 
  -Windows 98 - OS
  -APache webserver with PHP support
  -Mapserver 4.5 for my GIS files,

my webserver is not yet available on the internet, its
still in our intranet for testing then after any
approval from our boss, then we can upload it in the
internet.

i really need ur help, thank you and GOd Bless..

Robert,

www2.dmsolutions.ca has been down since Friday afternoon due to some
problems with our Internet connection, and it's not back yet... at this
point the telco and the ISP are fighting on who's responsible for the
problem, and we're stuck in the middle of this.

I have setup a mirror of the HTML pages that used to be on www2 at

Subject: [mapserver-users] Connect to the Geography Network
Message-ID: <006a01c1f05d$1ae7ace0$4991063d@fksg.utm.my>

Hi,

I got a few questions
1. Is Mapserver WMS compliant. If yes, starting from which version.
2. If I got an internet map running using Mapserver, how do I connect it to Geography Network. All I have to do is to register with GN. 
3. What is the advantage of registering with GN? All I can see is that someone using ArcGIS software can call a image/ streaming vector from the map service.
Like to hear from the list in regards of the benefits, compliance and security issues.

Thanks
Nyon

Subject: [mapserver-users] Getting Lat/Lon and Units in template file
Message-ID: <LAW2-F76EtwwUFN0lXh00006116@hotmail.com>

Hi all,
Two questions in one but might be related....  I searched the mailing list 
archives and didn't see anything, so I'm probably just missing some key 
ingredient..

I've tried the following parameters in my template file to get the extents 
in latitude/longitude but the tags never get replaced:
[mapext_latlon], [minlon], [minlat], [maxlon] [maxlat]
Projections are enabled and defined in my map file for each layer and for 
the map.  When I say "enabled" I mean that PROJ4 is compiled into the 
mapserver executable.  And it appears to be functional since my layers are 
actually lining up.  Any ideas?

Also, along the same lines, I'm not seeing how to extract the units (meters, 
feet, etc.) from the map file in the template file.  Is this not possible??


Thanks!!!!!

Message-ID: <scceae4d.030@em.agr.ca>

Hi all,
I have created an application that adds points to a map "on-the-fly" from an oracle database of lat long coords.  I used the mapscript "addfeature" to a "dummy layer" that was set up in my map file.  Hoever, I need to know how to then clear these added points from the layer, or make the layer void or something like that.

Any ideas?

Thanks,

I have the same problem with many different objects!
It happened with rectObj, layerObj, classObj for eample ... never with
mapObj.

I'inserted my "debug" print before the line suggested in the error
message ... 

I observed that:
- the object being tied is a scalar, and this is why the destructor is
called twice (i immagine !) one for the original variable and the other
for the "tied" virtual variable
- Not always the call to the destructor with a scalar value causes the
error!
- The problem seems connected to the use of a variable to store a
reference to an object. If I undef that variable the error disappears
(also if i have the same output in my debug ... see attached code ...)
- In some case the same code works perfectly !!! (as says Lowell this
suggest that the error is somewere else ... but I can't find it!!!)

----------------------------------------------------------------------
Here my "shenanigans" ... with rectObj

Modified DESTROY as:
  (/usr/local/lib/perl/5.6.1/mapscript.pm line 1801)

  sub DESTROY {
      print STDERR "==== destroing: $_[0]\n"; #ADDED LINE

      my $self = tied(%{$_[0]});
      delete $ITERATORS{$self};

Modified "constructor" TIEHASH  (in "father" package) as :
  (/usr/local/lib/perl/5.6.1/mapscript.pm line 16)

  package mapscript;

  sub TIEHASH {
    my ($classname,$obj) = @_;

    print STDERR "==== Tieing: $classname,$obj\n"; #ADDED LINE

    return bless $obj, $classname;
  }


Now execute ... 

sub ext_map {
  my $me=shift;
  my $mappa=$me->map(); # Here I've saved my map

  print STDERR ">>>>>> Start some debugging :-<\n";
  print STDERR ">>>>>> map->extent is: ".$map->{extent}."\n";
  print STDERR ">>>>>> now let's assign my \$ext=\$map->{extent}\n";
  my $ext=$map->{extent};
  print STDERR ">>>>>>  my var ext is: $ext \n";

  return;
}

This is the output in the error LOG!!!

NB:
  The error rise before return from sub to the caller.
  If I add "undef $ext" before "return" the error disappears!


Other test ...
Tring dumping the data before destroing ... all seems ok
data are there, object is not silently "gone".

added in DESTROY

  use Data::Dumper;
  print STDERR Dumper($_[0])."\n===========================\n";

They should not be permanently stored, so the next time you should start
with a void layer, unless you are actually saving the points to a shape
file which is not required to display them.

Can you show use how you are adding the points "on the fly"?
This is probably the part that needs to be changed.

well, you can't really clear the features unless you redraw the map. And if
you are redrawing, just simply don't add those features again.

Every object has a destructor method like so "obj->free()";

Turning the dummy layer off using:
$oLayer = $map->getLayerByName("dummy layer");
if ($oLayer->status ==  1) {
   $oLayer->set("status", "0");
}
should work?

very interesting. So far, the only place I have experienced this is with
mapObj, not anywhere else at all.


I am going to try Giorgio's shenanigans tonight :-)

Hopefully, I can make my scripts behave the same way. That should get us
further along to solving this.

One question for Giorgio... Could you please let us know what OS you are
using? I see you are using Perl 5.6.1, but on what kind of computer.

Thanks,
