I appreciate the posting of the mapplet java class. I believe it is a real
step forward for client interactivity.  We are trying to implement it with
png file support and are having problems (the main one being lack of Java
expertise).  Do I have to write a customized encoder/decoder with JIMI
(works with JDK 1.1) or do I need to try and make the applet plug into the
Java Advanced Imaging API I/O?  Need a point in the right direction.

Um, I don't know. I'm not a hardcore java programmer and know just enough 
to be dangerous. Looking through the PNG programming resources there are
a number of options. Current mapplet is 1.2 although it can be modified to work
with jdk 1.1. (can't keep the friggin version straight in my mind) 

Seems some folks aren't to thrilled with Sun's image loaders. Here's a java library
to use as a replacement. Supports PNG.

- http://www.vlc.com.au/~justin/java/images/

JIMI looks to be dead since Sun bought the company. Which leaves JAI, which 
appears to be in a state of flux too given what 1.3 is supposed to support.

I think I'd try the first link and see if it will build for you. I'll try here too.

We have an ArcInfo Library that I want to replicate to tiled shapefiles for use with MapServer.  I've set-up the directory structure on my mapserver box as follows: /gisdata/a1, /gisdata/a2, /gisdata/a3.../gisdata/j11.  So, I have a rectangular grid that I use for my index that has 110 tiles.  If my index.shp file is located in /gisdata, what should my .map file entry look like to draw section lines (sections.shp), for instance.

I had this working before, but can't seem to figure it out now.

Hi,

We have a client that wants to setup a network of satellite servers
based on MapServer and compliant with the OGC-WMT specs.  I know that a
little while ago, Doug Nebert made available a first version of an
OGC-WMT wrapper for MapServer written in MapScript.  I haven't given
this wrapper a try yet, but I would be interested in hearing the status
of that project and any other effort that might be happening on that

Also, since Doug's wrapper uses Perl, and our client wants to use some

succesfully used the Perl version of MapScript on Win NT.  I am already
familiar with compiling, installing and using MapServer on NT, but I
haven't used Perl on NT myself, so I am looking for hints on the best
Perl solution with Apache on WinNT, and also any MapScript compilation

We have a plan in place to make MapServer fully OGC compliant as a
server AND a client. Sorta waiting for funding though. The wrapper you
speak of is not based on MapScript. Plans are to leverage MapScript
heavily when building the OGC wrappers. Folks at the UMN can speak
to timelines.

As far as I know nobody has compiled MapScript on NT. I don't suspect
many have tried. The SWIG (swig.sourceforge.net) website details how
to build modules for use with ActiveState's perl release. ActiveState has
probably the best NT perl release.

Hi,

the perl wrapper is workable but needs some work.

also JRC in Italy have built a mapscript version using WMS 0.1 - this is trivial
to update to WMS 1.0. Its at the same level of complexity.
I have mapserv and the wrapper running on UNIX and NT - in fact its all running
under W98 on my laptop.

TODO #1: We need to build a GML response to getFeatureInfo query - GML issues
are being thrashed out now - this should be easy enough to do.

TODO #2: The big issue is CGI control over projection - I've yet to see a
working example of the syntax and havent had time to reverse engineer the code
to try. The script will have to map EPSG codes into mapserver (PROJ 4)
equivalents.

TODO #3: we ought to give it the ability to parse the .map file and build the
capabilities XML automatically.

The wrapper can run on any web server - so we dont need to have access to the
actual installation to make it WMS compliant - however to parse the map file we
would. Any ideas how best to overcome that?

Couple of comments. All aspects of the WMT (with the possible exception of #2) are
supportable via MapScript. Plans are to use MapScript to support all the get functions,
should be pretty straight forward. Since MapScript can interact with shapefiles and
inline features directly SVG support is not out of the question either.

On the projection end. Word has it that Frank Warmerdam is looking into adapting
Proj.4 to accept EPSG codes too. Hopefully that means not mods to the MapServer
will be necessary. Will have to check on this one.

A MapScript based solution would need to directly interact with any application data and
configuration files to build an image, do a query or return features using SVG or whatever. 
There is no redirection like the current script. In those cases I think it'd be necessary for 
the wrapper to live with the application. I don't think that's a bad thing since it keeps
things in one place. There are certainly enough other ways to make apps look like they
live one place when they're actually someplace else.

Brian,

We do that kind of things, but we use MapScript... there might be ways 
to build a URL using the regular MapServer and do the same. 
Unfortunately none the apps that we have built and do that are publicly 
available yet... but here is an idea of the way we do it:

When the user does a query in the main HTML page that contains the map 
then you use JavaScript (or MapScript in our case) to build the URL that
will generate the query result and open the identify window using 
something like:

newwin = window.open("/cgi-bin/mapserv?all_identify_query_params_here",
                     "IdentifyWindow",   
"alwaysRaised=1,scrollbars=1,titlebar=1,toolbar=1,status=1,location=1,dependant=1,resizable=0,menubar=1");

This could probably be executed in the "onSubmit" callback of your form
if you do not want to submit the main page.  In our case, we have that
line execute as the main map page is reloaded because we need to modify
the main page after the query. 

I guess you probably had figured that out... so we can tell you that it
works very well.  Except for one thing... if the identify window already
exists, and it is behind your current browser window, then the call to
window.open() WILL NOT bring it back on top... and your user will think
that the query did not work.

The trick to go around that is to embed the following JavaScript line IN
THE BODY of the identify window so that it is executed as it loads:

	self.focus();

This trick works well with both I.E. and Netscape.

Good Luck!

This is pretty easy using the standard MapServer or MapScript for that matter. You just need a little javascript to change the form target when the mode changes. That's how the data deli works. When a user wants to do a query, just before submission a results window is opened and the target property of the form is changed to use that window. That target could be a frame, a window or even a css layer. To do this implement an onSubmit
method for your main form and do a little checking just before submitting the form.

BTW LandView and it's underlying code will support this as well.

Hi List

I am pretty new to the mapserver-software. I like the idea and concept
behind it and I would like to use it for small mapping applications and/or
prototyping.

So I would like to know whether there are restrictions on the use of the
software and/or a licence? ( I didn't find one on the homepage...)

TIA

Subject: Can't get results from querying line shapefiles
Message-ID: <200005080724.RAA11868@eos.erin.gov.au>

Hi,

I can query polygon shapfiles but I can't query line nor point
shapefiles using mapserv.

I get the following error in an HTML page:

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

An error has occurred in msQueryUsingPoint(): General error message. No
matching record(s) found.

Please contact .....

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

I am calling mapserv with the following URL:

http://atlas/cgi-bin/fornet/mapserv?map=/info/cgi-data/atlas/tmp/22217.map&imgex

My 22217.map file looks like this:

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

and rail.html looks like this:

<li> From node: [FNODE_]</li>
<li> To Node: [TNODE_]</li>

</menu>

<p>

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

which is similar to what I use for querying polygons which works.

I'm not sure which mapserv version I am using.  Is there some way of
getting the version number?

I would greatly appreciate if someone can give me some indication as to
what I am doing wrong?

Thank you in advance.

perhaps it would help to put the license on the web pages.
I think it is important especially because it is not identical with the MIT
license and hence is actually not the MIT license.

The difference is in the second paragraph. I am not sure which change of intention
is aspiered with the different wordings. If there actually is none
it might be less confusing to just use the MIT license as is.
If there is another intention, IMHO it should be additionally explained.

All the best and keep up this wonderful software

Hi there,

I have point shape file (places with coordinates) and I would like to
search for place name and after that to draw on the map marker (icon)
with label - I don't want to draw the other places and the other labels
for this shape file - I'd like to draw just the desired place and label

QUERYMAP just changes the color of the selected features.
I send a picture - one example of what I need to do.
So any idea how-to?

Marin,

I am doing something similiar to this.  I am using dynamic expressions to
change the map file parameters on the fly.  This is done in the query
template file.  By using something like this:  <img src=
cgi-bin/mapserv?map=mymap.map&map_layer_1_class_1_expression=([attribute]
eq somevalue)&mode=map>

This is one way to approach it, but I am sure there are plenty others.

How are you doing the query? Normally you have a form control that
changes the mode to one of the query modes. At that point you should
not be panning and zooming and should not get a redraw unless you're
using query maps or something else funky.

Which querymap type are you using? Sounds like the default, HILITE.
You can use SELECTED to draw just the selected features. They are
symbolized as defined in the map file and not using the hilite color.

I agree that it would be great to have a page on the web site that
contains the official license.  Then right at the beginning it would be
clear for new users that MapServer comes with no strings attached, a big
advantage over other pseudo-free packages.  

I know this information is already in a README somewhere, but you have
to download the source and find the README before you have your
licensing questions answered.

Hi!

can you tell me:

- may I make a query based on more than one attribute? What is the syntax?

- does the mapserver contribute national character sets (in querying,
labeling). How can I make it possible?

Thanks, I know how crontab works. I was only hoping there existed some
feature in mapserver which deletes the gifs.

Message-ID: <Pine.LNX.4.21.0005091049180.9890-100000@icestorm.tfcc.com>


Howdy,

I'm presently using Perl/Mapscript to connect to a remote database,
retrieve coordinate data, generate a shapefile, and then, from the
shapefile, generate an image.

What I'm having problems with is that I'm generating the shapefiles okay,
but when I look in the shapefile object, the numshapes attribute is set to
zero which means I can't iterate through it to draw all it's shapes.

According to the documentation, numshapes is a read-only attribute so I
assumed it would be updated automatically.

Here's some sample code (paraphrased :)

    foreach $layername (@layers) {

      	print "Generating $layername\n";
	$sth->execute(uc $layername);
	($layer_id, $type) = $sth->fetchrow();

	print "  Generating shapefile\n";

        # This returns a ShapefileObj
	$shapefile = GenShapefile($dbh,
				  $dbh_dbf,
				  $type,
				  $layer_id,
				  $layername,
				  $extent);
	
	print "Getting layer";
	$layer = $map->getLayerByName($layername);
	
	for ($i=0; $i<$shapefile->{numshapes}; $i++) {
	    
	    print ".";
	    $class = new classObj($layer);
	    $shapefile->get($i, $shape);
	    $shape->draw($map, $layer, $img, $class, "An object");

	} # for ($i=0; $i<$shapefile->{numshapes}; $i++) 
	print "\n";

	undef $shapefile;

    } # foreach $layername (@layers) {
    
    print "Saving image\n";
  mapscript::msSaveImage($img, "temp.png", 1, 1);

My question is that is $shapefile->{numshapes} supposed to be updated
automatically or do I have to keep track of it myself?  

I am using version 3.3.010 of MapScript with GD 1.7.3 compiled in.

Cheers!

Have you tried closing the shapefile after it's been created and then
repoening it in read access?

I ran into a similar problem (on Windows)... I was creating shapefiles
using the PHP/MapScript which is based on the same functions as the Perl
MapScript, and I realized that the last changes to the shape file do not
appear to be flushed to disk until the file is closed.  Closing the file
and repoening it solved the problem... I have to admit that I didn't
look into the MapServer code to try to understand what was really
happening.

That worked. :)

Now if I can figure out why the following crashes:

  $shape->draw($map, $layer, $img, undef, "$i");

Suggestions?  If anyone needs any additional info, please let me know.

Whoops.  Figured out I wasn't preparing the Image first.  It's generating
an image now :)

How about querying?  If I select a set of records from an SQL database
that contain LAT/LON coordinates and only want to map those points, this
can probably be done the way you suggest above.

However, is there any way to query the same set of points in memory
without creating a shape file on disk?  My main concern is that I don't
think shapes in memory carry any kind of attribute information (or maybe
I overlooked that?), so even if I could query them in memory, how could
I keep the link between the shapes in memory and the SQL records in
order to display info from the database in response to the query?

Any ideas about that?  Or maybe it's just some parts of the shape object
handling in MapScript that I have overlooked?

Thanks,

Subject: MapScript Shapefile Object
Message-ID: <s9182037.042@gwgate.dnr.state.mn.us>

Presumably there is another mechanism to filter points before they
are fetched, ala SQL. ShapeObj and pointObj are nothing more than
containers for storing the spatial information. There is no attribute
component what so ever. That doesn't mean they can't be part of
larger structures that integrate the two types of attributes. Then you
can do whatever your particular scripting language supports. MapScript
has no provision for searching a list of features outside the shapefile
environment. The functions to implement those types of operations
are in place as distance and intersection methods. That sort of processing
should only really be needed when accessing data that is not part of
someother management system (i.e. RDMSes) like ascii files.

How about querying?  If I select a set of records from an SQL database
that contain LAT/LON coordinates and only want to map those points, this
can probably be done the way you suggest above.

However, is there any way to query the same set of points in memory
without creating a shape file on disk?  My main concern is that I don't
think shapes in memory carry any kind of attribute information (or maybe
I overlooked that?), so even if I could query them in memory, how could
I keep the link between the shapes in memory and the SQL records in
order to display info from the database in response to the query?

Any ideas about that?  Or maybe it's just some parts of the shape object
handling in MapScript that I have overlooked?

Thanks,

Hi
Is it possible to prevent [img], [legend] and [ref] from being created?
I have one html page where the map, legend and reference map are shown.
When user queries, a new page is opened showing query results, but no
map(s) whatsoever. Still, the images are created.
Maybe it's possible to use two different map files, ie query.map and
browse.map?

TIA Berend

It's not in the code right now. It's not that it isn't technically feasable it's just that
it would kill performance. I assume you want to annotate and/or classify based
on this external data? I can look into it for a future release but it won't be added

You can do this using mapscript.

Subject: How to zoom to place names
Message-ID: <39199786.7020701@usgs.gov>

I have a need to use my map interface in two ways: 1) for the 
geographically literate, let them zoom in by dragging a rectangle and 2) 
for the spatially-challenged have a picklist of places that they can 
click on and have the map zoom to that location upon request.

How should I package and translate such place names (they have envelope 
bounding rectangles associated with them) so that a refresh_map event 
would request a new map to be drawn for that area?

How should I structure the names service? The biggest trick is that I 
have a large number of place names I could bring to use from an online 
gazetteer of 700,000 placenames! But I think I will start small with 
political subdivisions and big cities that only number in the thousands.

Any hints or examples of code as to how I might structure this would be 
most helpful, and the kind of thing I would think many would like to see 
in a demo FAQ.

I assume you are using mapscript?

I've done something similar with mapscript.  First a user selects a
placename from an HTML select form that parameter gets passed to the script,
which looks up the placename in an SQL database and grabs the points and the
bounding box; the bounding box gets parsed as the map extent (with a little
padding) and the point is rendered and labeled.  I can post some code, if in
fact you are using mapscript and would like to see it.

One browser problem I've run into and something to consider: very large
select lists sometime break browsers.  I've used a placename list that are
over 2000 items long and had Netscape go down in flames (only on Macs).
This is probably just a simple memory allocation problem, but it does affect
the end user's experience with your work.

Here is a little bit more on crontab:

You need to ensure the cron daemon is started.   Begin by editing a
crontab entry.  This invokes your default text editor (e.g., VI or
emacs).  Don't simply edit the crontab file...use the following command:

crontab -e

Enter your parameters in this file.  Each line represents a command with
parameters.  This example blows away everything in the temp folder daily
at 03:30.  You can use wildcards for defaults.  Obviously, you should
double check your commands and settings so you don't run a command you
regret!

30 3 * * * rm -rf /home/httpd/temp/*

The format is MINUTE HOUR DAY_OF_MONTH MONTH DAY_OF_WEEK COMMAND
Use a comma to separate multiple values and a hyphen to indicate ranges.

If you need more than this, pick up a UNIX command reference.  I did not
find the man files overly useful for crontab.

I'd use an external database to hold my points, query it and use the
results to initialize MapServer sessions. That's what we do here with
the GNIS database for Minnesota. You can use the point and then 
either a scale value or a buffer (i.e. 5 miles) to initialize an interface.

Unless you have a relatively small set of points of interest, pull down
lists get bulky. I suppose you could regionalize them so the list changes
as you zoom or pan, but that seems like an awful lot of work.

Message-ID: <Pine.LNX.4.21.0005111150010.16145-100000@icestorm.tfcc.com>


Howdy,

Having an interesting problem with getting MapScript/Perl to correctly
pass a gdImagePtrPtr type to a subroutine (you get a gdImagePtrPtr type
when you call $MapObj->prepareImage()).  What's happening is that I'm
finding that the gdImagePtrPtr type is exceptionally volatile.  Here's an
example of what I'm trying to do:

main : {

  # blah blah blah

  $img = $map->prepareImage();

  RenderBase($dbh,
  	     $cgi,
             $img);

  # Do some other stuff ...

  mapscript::msSaveImage($img, "temp.png", 1, 1);

} # main

Unfortunately, this doesn't work.  It produces a blank image.  I believe
that somewhere down the line, $img is getting clobbered at one point or
else is pointing to memory that's been deallocated.  Now, something like
this *does* work:

sub MySubroutine {

  $img = $map->prepareImage();

  # Generate Image ...

  mapscript::msSaveImage($img, "temp.png", 1, 1);

} # MySubroutine

Essentially, what I'm trying to do is successfully pass $img to a
subroutine and then get the new value back.  I've tried the following to
no avail:

* Make $img a global variable

* Pass in $img and make the subroutine return the new value

* Pass in $img as a reference and dereference it within the subroutine.

* Pass in $img as a regular variable and assume it's pointing to the
  correct data.

I've gone through the perl debugger and it looks like $img is pointing to
the same address space throughout which leads me to the conclusion that
somewhere down the line, the memory is getting deallocated.

Does anyone have any experience with this?

A quick heads up-

In our implementation of the OpenGIS "USL pilot" we are exploring the use of
XML encoded gazetteers - static at this stage but looking for standard
query/response behaviours next.

The mapimage applet is being used to show locations as the user hovers over a
list of placenames generated from this list, and an OGC map call used to access
the base map for the applet.

This will all be released (mapinage source) and an example visible within about
a week

Hi,

I got the following error when I tried to initiated the script with
browser:

ld.so.1: map.cgi: fatal: libttf.so.2: open failed: No such file or

Ma,

I got the same error after I moved mapserv from one machine to another.  I was 
able to solve the problem by editing the Makefile and putting the full path name 
to the libttf.a library file.  Eg.

TTF_LIB=-L./gdft -lgdft /opt/contrib/lib/libttf.a

I hope this helps.

Sorry guys. This should get easier. Dan Morissette has contributed auto configure
scripts for the next version. They are in the CVS and nightly builds now and seems
to work great.

Unfortunately, I do not think that the current version of the configure
script will solve that problem though. 

It seems to me like this is not a compilation problem, but a runtime
library path problem where libttf.so.2 is not found in the regular lib
search path.  This type of problem is never fun... I ran into a similar
thing on a SUN system that I use and that has a specially odd
configuration.  I tried setting LD_LIBRARY_PATH before starting Apache
but that did not work.

Since I did not have root access on that system to go change the system
lib path (/etc/ld.so.conf), the only way that I found to go around the
problem was to use ld command-line options to add the directory where my
libs are to the runtime library search path... something like...

Using gcc:

  gcc -G -Wl,-R -Wl,.:/path/to/my/libs  ......

or using ld directly:

  ld -G -R.:/path/to/my/libs ....

These are options for the ld that I had on Solaris 2.6, I think that on
Linux the "-R" option would actually be called "-rpath".

BTW, I guess a simpler solution would be to link with a static libttf.a,
as someone suggested but unfortunately freetype does not build libttf.a
by default... so you're stuck with shared libs only.

Also, I think (but I didn't try it myself) that linking your shared lib
using an absolute path instead of using the "-L" linker option might
allow your executable to find the lib at runtime without having to
modify the runtime lib search path.  

e.g. In the Makefile, try using:  
       TTF_LIB=-L./gdft -lgdft /opt/contrib/lib/libttf.so

Please let us know if any of that solves your problem and we'll try to
give the configure scripts the ability to handle those odd cases.

Configure will fix the compilation. Dealing with shared libraries is another problem
entirely. It's best handled in the web server configuration. Both netscape and apache
have directives directives to set environment variables for CGI scripts. I've used both
servers with mapserver and shared libraries with no problems. In apache for example
you simply add:

setenv LD_LIBRARY_PATH /usr/local/lib

to httpd.conf and restart.

Makes complete sense... I knew there had to be a proper way to pass
environment vars somewhere in the Apache configuration but never managed
to find it!

As many might be aware, the OpenGIS Web Mapping Specs include definition 
of capabilities in XML and the current pilot is working on specification 
of symbolization using XML structures. It would be nice to see what 
similarities there are between WMS and mapserv and use them.

XML is now a pervasive technology with many parsers available to read 
through encoded files (It will get better as XML-Schema is used). Sounds 
like a good idea to me.

Doug.

Doug, Can you provide a URL reference to the OpenGIS XML topics?
I looked thru the list, but no mention of XML on the index page.

Moving to an XML config is probably the way to go, but guaranteed to
break the existing applications that use the old mapfiles.  That
would be painful to change all those mapfiles I have all over the place.
Maybe a mapfile->XML conversion tool would be the ticket... or some way
to accomodate either configuratoin as a stop-gap measure.

I dont know for sure, but I suspect that XML is versatile enought to support
all of the baggage we carry in the mapfile.  Maybe we can come up with some
concrete examples of how this might look?   What this boils down to, is nested
map objects (and the objects which make up a map) and if XML can support that,
it would make perfect sense to persue that goal.

The Web Mapping Service specifies each server's "capabilities" using a 
hierarchical markup in XML for the server and a repeating section for 
each "layer" which is analogous to named layers in mapserv. This 
capabilities.xml file can be placed at a WMS server site for harvest 
into a services registry (so we know what map servers exist) or for 
interrogation by middleware or a smart client to offer layer choices to 
a user. See the WMS Get Capabilities interface specification.

Also, any day now, the Geography Markup Language (as Recommended Paper) 
will be available for public review. It is not a specification, and 
despite the apparent similarity to a W3C "Recommendation", this is only 
a first step towards a future spec. GML has several flavors of 
implementation, but essentially encapsulates mapped Features, their 0- 
1, and 2-D geometries, and attributes using XML markup. It is intended 
for use where a client wishes to cache objects for display and query 
without re-visiting the server and could be viewed as a type of export 
format for extracted or full vector data. The next phase of Web Mapping 
Testbed will take GML further towards a specification, but soon the 
recommended paper will be available for you to experiment with.

Supporting either might be a good idea.

XML most certainly stores hierarchies of information (think outline) 
with repeated groups, most elements having a starting and ending tag. 
The creation of a "rule" document, called a DTD, would help enforce or 
validate the map file. One quirky thing, but some parsers are very case 
sensitive, so the case of the tags you declare matters... See attached 
example of the demo map file manually converted to XML. Don't 
necessarily trust my assignments, but by defining these rules of 
encapsulation it will make the composition and testing of map file 
contents better.

Doug.

Pretty straight forward I'd say. How does one make the decision between
making a a parameter a new tag or just having it as an attribute of another
tag? For example:

  <layer><name>water</name>  vs   <layer name="water">

Once a DTD is in place a conversion script should be a piece of cake.

The Web Mapping Service specifies each server's "capabilities" using a 
hierarchical markup in XML for the server and a repeating section for 
each "layer" which is analogous to named layers in mapserv. This 
capabilities.xml file can be placed at a WMS server site for harvest 
into a services registry (so we know what map servers exist) or for 
interrogation by middleware or a smart client to offer layer choices to 
a user. See the WMS Get Capabilities interface specification.

Also, any day now, the Geography Markup Language (as Recommended Paper) 
will be available for public review. It is not a specification, and 
despite the apparent similarity to a W3C "Recommendation", this is only 
a first step towards a future spec. GML has several flavors of 
implementation, but essentially encapsulates mapped Features, their 0- 
1, and 2-D geometries, and attributes using XML markup. It is intended 
for use where a client wishes to cache objects for display and query 
without re-visiting the server and could be viewed as a type of export 
format for extracted or full vector data. The next phase of Web Mapping 
Testbed will take GML further towards a specification, but soon the 
recommended paper will be available for you to experiment with.

XML most certainly stores hierarchies of information (think outline) 
with repeated groups, most elements having a starting and ending tag. 
The creation of a "rule" document, called a DTD, would help enforce or 
validate the map file. One quirky thing, but some parsers are very case 
sensitive, so the case of the tags you declare matters... See attached 
example of the demo map file manually converted to XML. Don't 
necessarily trust my assignments, but by defining these rules of 
encapsulation it will make the composition and testing of map file 
contents better.

Some of it is justa  matter of style. I like to put things as properties 
on a line when they are almost always present, just to shorten the 
length of the file. I like the idea of knowing which named Layer block I 
am in expressly, rather than parsing it, though the other form of using 
only straight tags works well enough, too.

There are DTD generators that can use example XML markup to build the 
interpreted rules and values. I will look for one and pass the demo.xml 
through it. You will need to expland this to include all the various 
possibilities of terms within a given group, and other possible groups 
that may exist but were not expressed in the demo.map file. You can edit 
the DTD by hand to include these.

Subject: DTD and fixed XML example for map file
Message-ID: <39216B1D.2080605@usgs.gov>

Found a neat validator/DTD generator at: 
http://www.pault.com/Xmltube/dtdgen.html

Attached are a validated XML instance file and the DTD generated from 
it. Note that DTD elements are presented in alphabetic order rather than 
in logical order. Read the results carefully!

However, when an item shows up as a part of another item (e.g.) WEB has 
HEADER and TEMPLATE, the parsing expected order of these subfields is 
rigorous in XML 1.0. You can't, say, legally switch the order of 
occurence of TEMPLATE and HEADER in a picky parser. I imagine future 
implementations based on XML-Schema will relax the element order and 
case sensitivity requirements of the current generation.

Subject: MapServer and XML...
Message-ID: <200005162319.JAA18232@eos.erin.gov.au>

Hi,

We use XML to store all our layer and server information.  We are
waiting for OGIS to be finalised and to see how many people use it
before we change our own XML structure.  (After all SDTS appears to be
not widely used.)

We convert the XML information into dynamic map files on the fly for
the ForNet mapserver to present gifs and queries.

Your question on whether to use attributes or elements has been argued
amongst the XML and SGML community for a long time.  I like the
approach of using elements when they can mean something to the public
and attributes for the system variables.  For example.

<layer LID="L47" DSID="D1">
 <name>Coasts</name>
 <type>point</type>
  ...
</layer>

Where "LID" equals "Layer IDentification number" and "DSID" equals
"DataServer IDentification number".  These are used by the WWW
presentation software and for layer indexing.

The only restriction to the attributes is that you can't have duplicate
attribute names.  This will be identified if you try to parse your DTD
or an instance of your document against your DTD.  So the lession to
learn there is use them sparingly.

That's my two cents worth.

Hi,

I was wondering if anyone has been able to access SDE layers using the
mapserv program.  If so could you show me an example of your .map
file and how you get mapserv to point to the SDE layers?

We have our layers on a separate machine inside our firewall.  We have
the SDE client software on the same machine as the mapserv program.  We
already obtain access to the SDE layers via a C program using the SDE
APIs so it should be easy to access the SDE layers using mapserv.

Thanks in advance for your help.

Looks like a problem finding shared libraries for freetype. On solaris you can set the environment variable LD_LIBRARY_PATH to contain the paths (seperated by :'s) of directories containing shared libs. Try doing that and running the dump script again.

Hello,

I've been trying to figure out how the queries work with mapscript and 
was hoping someone could shed some light on it. I'd like to do a simple 
point in polygon query and get access to the dbf record for that polygon. 
The script is crashing on the line that calls queryByPoint with an 
internal server error. If anyone has some code that deals with queries in 
mapscript and are willing to share I'd be very appreciative.

Thanks,
paul

Here's the code that's relevant to the query:

#!/usr/local/bin/perl

use mapscript; 
use CGI qw(:standard :html escape);

$cgi = new CGI;  
$query_type = $mapscript::MS_SINGLE;  

$mode = $cgi->param('mode');  
$x = $cgi->param('img.x'); 
$y = $cgi->param('img.y');

$mapfile = '/usr/people/pcameron/survey/scott/web/mapscript.map';

$map = new mapObj("$mapfile") or die "Unable to load map file. ", 
$mapscript::ms_error->{message};

if ($mode eq 'query') {
  $query_buffer = 10;
  $query = new queryResultObj;
  $point = new pointObj();
  $point->{x} = $x;
  $point->{y} = $y;
  $query = $map->queryByPoint($point,$query_type,$query_buffer);
  &process_query;
}

Core dump? or no queries returned?

I'm guessing that this is your problem - setting the buffer size to -1
should 
use each layer's tolerance.

Then you have to do something with the query itself. Here's what I do in
TCL 
(this exposes shortcomings of SWIG/tcl - it's close to unreadable.)

------
   set p [canvas2point $c $config(map) $x $y]

   if {[set q [mapObj_queryUsingPoint $config(map) $p 1 -1]] != "NULL"}
{
       queryResultObj_currentlayer_set $q 0
       queryResultObj_currentshape_set $q 0
       for {set s [queryResultObj_next $q]} \
            {[shapeResultObj_layer_get $s] >= 0 &&
	    [shapeResultObj_shape_get $s] >= 0} \
	   {set s [queryResultObj_next $q]} {
             $txt insert end " $s, layer [shapeResultObj_layer_get $s],
shape [shapeResultObj_shape_get $s]\n"
             set dbf $config(dbfFile)
	     if {![file exists $dbf]} {error "missing dbf $dbf!"}
               set h [DBFOpen $dbf rb]
	       set w [DBFGetFieldCount $h]
	       for {set i 0} {$i < $w} {incr i} {
                  set name [DBFGetFieldName $h $i]
		  set value [DBFReadStringAttribute $h [shapeResultObj_shape_get $s]
$i]
		  $txt insert end "$name $value\n"
               }
	       DBFClose $h

Subject: mapscript query question
Message-ID: <s9250457.002@gwgate.dnr.state.mn.us>

What happens when you run it from the command line and feed it a point? Also, you don't need the new queryResultObj. That constructor is only necessary when reading cached queries.

Hello,

I've been trying to figure out how the queries work with mapscript and 
was hoping someone could shed some light on it. I'd like to do a simple 
point in polygon query and get access to the dbf record for that polygon. 
The script is crashing on the line that calls queryByPoint with an 
internal server error. If anyone has some code that deals with queries in 
mapscript and are willing to share I'd be very appreciative.

Thanks,
paul

Here's the code that's relevant to the query:

#!/usr/local/bin/perl

use mapscript; 
use CGI qw(:standard :html escape);

$cgi = new CGI;  
$query_type = $mapscript::MS_SINGLE;  

$mode = $cgi->param('mode');  
$x = $cgi->param('img.x'); 
$y = $cgi->param('img.y');

$mapfile = '/usr/people/pcameron/survey/scott/web/mapscript.map';

$map = new mapObj("$mapfile") or die "Unable to load map file. ", 
$mapscript::ms_error->{message};

if ($mode eq 'query') {
  $query_buffer = 10;
  $query = new queryResultObj;
  $point = new pointObj();
  $point->{x} = $x;
  $point->{y} = $y;
  $query = $map->queryByPoint($point,$query_type,$query_buffer);
  &process_query;
}

There is some documentation for this in the CGI reference on the website, way at the bottom. The example is for a point but can be used for lines and polygons. Only difference is that the list of points is longer (remember closure for polys). How you populate the CGI vars is up to you.

A good global dataset can be generated from the DCW (Digital Chart of the
World), which may be a little expensive. Naturally, you have to read the
License agreement and make sure you have value added to your maps before
putting them on the web.

Howdy,

This might be slightly off topic, but I've presently got a
web-based mapping/reporting system that I've got up-and-running.  I'm
using the MapScript perl module and am talking to a Postgres Data Base
with all the geodata on it.  The layout of the data base is similar to an
ESRI shapefile (I can be more detailed if you want).

The main problem I'm having is data base performance.  I've tinkered with
the data base and have added enough indexes to make a considerable
difference in performance.  I've also limited the number of layers I'm
drawing when my scale is above a certain point.

It looks like what we'll have to do is simply purchase faster
hardware.  When I moved the data base from a Solaris x86 box (either a
P-233 or an AMD K6-300) to a Linux Box (450MHz K6-III) I got close to a
50% improvement and that's with the Linux box running the web server, perl
script, AND Postgres.  If anyone has any additional recommendations as far
as laying out the data base is concerned, please let me know.

Also, anyone have any experience with Oracle Spatial?  Is it worth the $$?

Finally, if anyone wishes to use PostgreSQL as a low-cost solution for
writing a GIS type application, I can heartily recommend it.  It comes
with some nice geographic data types and functions.  It also plays well
with Perl.

Chris:

Did you investigate the use of Sybase, Informix, DB2, or Oracle 8i for 
the Linux platform? Almost all of these are available for Linux now at 
no or low cost (Sybase came with RedHat 6.1; Oracle can be obtained with 
an unexpiring demo license) and most/all? support stored procedures and 
extensible data types. My understanding is that PostgreSQL is intended 
for research and demo applications but was never tuned for performance, 
just a testbed of features. It would seem to me that one of these other 
databases could be rigged to store each primitive with a searchable, 
indexed bounding envelope to return the feature as a BLOB. Or, for a 
chunk of change you could use tuned tools such as Oracle Spatial or SDE...

What are others' experience? It would be very nice to have a low cost 
database engine to feed the mapserver. It would be even nicer if folks 
built their interfaces following the OpenGIS "Simple Features via SQL" 
access model. Then different brands of compatible databases could be 
accessed using the same SQL calls. This doesn't eliminate the need for 
database tuning, but allows for a common request interface.

Chris,

You might look into the new PostgreSQL 7.0.  I haven't used it yet, but
one of the changes listed on their announcement is:

	"Optimizer Overhaul:
         Continuing on work started a year ago, the optimizer has been
	 overhauled, allowing improved query execution and better
	 performance with less memory usage. "


The rest of the announcment can be found here:  
http://www.postgresql.org/news.html

Might be helpful,

John

I decided to use Postgres for development purposes and have found it to be
a pretty good test platform; however, the final product will probably be
running on an Oracle data base running under Solaris x86 since that's what
our other applications run on.

I am curious if Oracle Spatial would help :)

I've do a lot of the same things with my PostGreSQL database set up.
Indexing does help performance.  I usually perform all my queries by
bounding box -- I've got a table/index of all the layers and their
bounding boxes which also helps eliminate the need for hitting the layers
themselves over and over again for usesr queries.

I have Oracle for Linux, but haven't tried making the mapscript connection
yet.  The problem with these databases (I have experience only with Oracle
and DB2) is that they are extremely difficult to set up initially, and
true site licenses can be prohibitively expensive (at least for my
office).  Once they are up and running, they really are quite nice. I'd
say if you have access to, and dedicated support for, Oracle or DB2 by all
means use them, but if you don't it may not be worth the investment in
time and effort that it takes to get them off the ground.

I'd have to say PostGres is a good fully functional alternative is easier
to manage on one's own, and is catching up with the big boys.  PostGreSQL
7.0 has just been released and boasts better performance -- although I
haven't tried it yet. There's also a FAQ about fine tuning PostGres for
better performance: http://www.postgresql.org/docs/faq-english.html#3.10

See: http://www.opengis.org/techno/specs.htm#implementation

Both Oracle 8i Spatial and SDE (and others) can set up alternate access 
via a configuration switch. OGC Conformance testing has been arduous but 
seems to be getting easier with the suggestion of self-test 
certification in order to really wear the OGC "label". This means there 
may be untested but compatible implementations of Simple Features 
(SF-SQL) out there. It would be nice to see someone make PostgreSQL be a 
compatible SF-SQL solution!

Lot's of ways depending on where the geographic thesaurus data
resides, whether you're using the mapserv cgi program or mapscript.
In general though you'll probably need to use dynamic features given
on the URL. Based on the place search you'll identify a place. You can
use it's coordinate to create a map extent and can place the point
and annotation dynamically.

If you have a layer called mypoint that defines how the place should
be symbolized and annotated then adding

...&layer=mypoint&map_mypoint_feature=new&map_mypoint_feature_points=some x+some y&map_mypoint_feature_text=place+name...

There are ways to make this sticky in templates too.

this functionality into mapserv (a web page).  Is there some hook into

[img]????).  Has anyone done this? I'm using 3.3.009

You have to use gd-1.3 or higher for 8-bit fonts and 8-bit font support.
gd-1.3 comes with ISO-8859-2 bitmap fonts directly, which is fine for the
Central European alphabets (the other users have to fix them for their
national character set). It works perfect with ttf also.

I guess it's time to make an official announcement for the PHP/MapScript
module...
 
PHP combined with the new PHP/MapScript module would allow you to do
exactly what you ask here.  If you know Perl already, PHP should not be
too hard to learn and you should get the same functionality from the PHP
MapScript module that you used to get from the Perl MapScript module
(Except for a couple of functions that are not implemented yet).


The PHP module is now available on the CVS server at UMN under
mapserver/mapscript/php3/.  I expect it to be included in the next
source code release of MapServer (version 3.3.011).

WinNT users can download a pre-compiled version of PHP3_MAPSCRIPT.DLL
from
http://www2.dmsolutions.on.ca/mapserver/php3_mapscript_dll-20000524.zip
and Unix users will have to get the source from the CVS server and
compile it.

I have started a FAQ for the PHP/MapScript module.  
    http://www2.dmsolutions.on.ca/mapserver/php_mapscript_faq.html

At this point it contains pointers to the information you need to get
started (compile and install the PHP module), and I expect that it will
grow as we get feedback from users.  

Enjoy!

Is getLayer() a functioning method, or is it one of the missing

Hi,

I installed MapServer 3.2 and the 3.2 Demo, and it works ok, but doesn't
draw the city names. 

I've downloaded some free true type fonts from the web, and put them in
/usr/apps/mapserv/symbols/fonts. Then, I modified the font directory name
in the mapserv.ini file. After that, I wrote two diferent fonts.list file,
because the README statement doesn't match the example file.
Unfortunatelly, neither worked.

After the message about the 3.3 demo, I decided to upgrade. But now, I
can't even get the first map. When initializing, mapserv displays the
following error message:

msLoadSymbolFile(): Unknown identifier. ():(0)

Any clue will help.

Thanks in advance,
M?rcio.

Until MapServer version 3.3.011 is released, Solaris and other Unixes
should get the source through the UMN CVS server.  The info to access
the CVS server is at:

	http://mapserver.gis.umn.edu/cvs.html

If you really can't get the source through CVS then let me know and I'll
try to prepare a package with the source.

i think your files may contain ^M at the end of each line. i had the same 
problem. more file.name didn't show it. but it did show in vi. you'd need 
to s/r all of the ^M (remove them).

I hadn't had these problem, because I've built up the files with ls and
awk. But the following message from Stephen Lime has put me in the right
way, and now I got the demo running.

Thank you very much indeed,

There was a slight change in line symbol file formats from 3.2 to 3.3.
Copy the symbol
files from the 3.3 distribution (in the symbols directory) to the demo
symbols directory
and that should fix it. You may still hit a few other snags but those are
mostly outdated
parameters and you can just delete or comment out those lines.

Marc,

The CGI will do whatever the application requires....
In our applications, as a base function, we do image
"Swapping" to no need for the CGI reload page bullshit.
In this case we have java call a mapscript CGI in the
image param that generates "Image Only".

Then you can modify the applet to handle other Mime
Types ;)

getLayer() is magically working now. Either I had the syntax wrong or
someone has changed something on the module.

i added extension=php_mapscript.so in php3.ini and restarted apache. now it 
core dumps so i can gdb bt it. found out that it wasn't finding all of its 
runtime libraries. so i added a few lines of those to the Makefile in 
mapscript/php3.

i then 'make' again. ran ldd on the lib:

# ldd *so
php_mapscript.so:
          -lc.12 => /usr/lib/libc.so.12
          -lttf.3 => /usr/pkg/lib/libttf.so.3
          -ljpeg.62 => /usr/pkg/lib/libjpeg.so.62
          -ltiff.3 => /usr/pkg/lib/libtiff.so.3
          -lgd.1 => /usr/pkg/lib/libgd.so.1
          -lm.0 => /usr/lib/libm.so.0

looks like they are all there now. then i load up the page:

phpinfo_mapscript.php3

and got:

Warning: Invalid library (maybe not a PHP3 library) 'php_mapscript.so' in 
(null) on line 21
...followed by phpinfo() stuff...

i left extension=php_mapscript.so in the php3.ini file and tried commenting 
out line 21, but it doesn't show the module in phpinfo. when i do this, 
there is no null error either.

Is there any way to test somehow if my mapscript build is correct ?

I install ActivePerl (Windows) and mapscript, but when I try to declare "use
mapscript", I'm getting "parse exception".

Message-ID: <Pine.SOL.4.05.10005300934560.29903-100000@river.hwr.arizona.edu>

I am using mapserver 3.3 and the mapscript Perl module. 

My perl program will not run with mapscript when I open it from a web
browser. It is in the cgi-bin and runs from the web without problem until
I add the line "use mapscript;" where it dies with an internal server
error.

The same program DOES work with mapscript when compiled and run from UNIX,
just not from the web. It think this might be a library path problem.
Before compiling in UNIX, I have to give it this command: setenv
LD_LIBRARY_PATH /local/tiff-3.4/lib:$LD_LIBRARY_PATH. I tried setting the
path in my .login file, but that didn't seem to help. I might have the
syntax wrong though. Here is the setenv line from my .login file: setenv
LD_LIBRARY_PATH /usr/lib:/usr/local/lib:/local/tiff-3.4/lib

Any suggestions?

Thanks -zm

If you're using Apache then the value of LD_LIBRARY_PATH is not
automatically passed to the CGI scripts.  You can add a PassEnv or
SetEnv directive to your httpd.conf with the value that should be passed
to your CGI scripts.  See:

    http://www.apache.org/docs-1.2/mod/mod_env.html#setenv

The answer to this is that the name of the method is queryUsingPoint().
Also, queryByRect() is actually queryUsingRect(), for the layerObj.
Probably the same for the mapObj.

Does anyone have Netscape/HTML client-side image-maps working?  Do they
work when you pan and zoom?

There is a quaint bug with Netscape 4.x that means imagemaps fail to work
if the page scrolling bar is not at the top of the page!!

Wierd? yes. Good? no.

I don't think it's possible to use an imagemap with a form image. As a work around I
have a new version of the applet that's been floating around to do box zooms that 
supports imagemap behavior. The applet reads an xml file that defines 'hot' areas and
the text to display (usually attributes of some kind). I'm still adding url support but that's
not really that useful since you can use the mapserver to process those queries anyway.
It's the mouse over stuff that seems the most useful. I've got this working with mapscript
only and haven't explored a programatic way to produce the xml files from the mapserv 
CGI program. Let me know if folks are interested.

Hmmm... Thought I replied to this last week. SDE support is not there yet. I have it connecting
and retrieving features but haven't had time to move past that yet. There's no way solaris libs 
will work on linux so it's not worth messing with. You'd be better off spending time bugging ESRI
and getting them to port enough of the SDE API to linux to build clients.

Anyone using MapServer to serve up SDE data yet?

We have an SDE for Oracle server set up with some of our data to test performance.  My MapServer is set up on a Mandrake 7.0 / Apache system.  Since the SDE client libraries and includes don't exist for Linux (yet :)), I compiled MapServer with SDE enabled using the Solaris libraries and includes.  It compiled fine and the MapServer works just as before when accessing shapefiles.  I have no idea if it's going to work with SDE (since I used the Solaris includes and libraries), but I'd like to test it.  Problem is, I don't know the correct syntax to include in my *.map file to access the SDE data.

Any hints?

Thanks,

Robert Aldridge

Let me tell you what I have planned, and see what you think.
Basically, I have a shell script which calls a program create.pl to place icons
on a map (right now, just polygons) by creating a shapefile.  Once
the shapefile is created, I call mapserv proper to process the
html page.

What I was thinking was that the create.pl could also create
the HTML page used by mapserv, with all the 'hot' areas in it.

What do you think?  One of the things I'm worried about is that
I'll have to do some transformations to get from map
coordinates to image coordinates.
