Subject: request for comments - SDE
Message-ID: <sa5062ff.048@smtp.dnr.state.mn.us>

Hi All: The comments so far have been helpful. One 
calrification I'd like to add is that even as just
another data source I still plan to allow a single 
SDE based attribute query that accompanies the 
necessary spatial query. The results will always be
processed through MapServer classes. If you take a
second to think about it this is *really* flexible. 
For example you can use an Oracle "decode" statement
to pre-classify entirely in Oracle/SDE and then use
simple MapServer classes to asign colors. So this is 
not quite as all-or-nothing as I had mentioned earlier.

MapScript may eventually open even more possibilities 
such as opening up OSVecDB/SDE spatial operations like
buffering to shapes retrieved from anywhere.

Greetings all: I'm screwing around with new code to
allow broader support for queries etc. At the heart of 
this discussion is whether consider SDE as simply a
data source or data processor. As it sits the current 
code utilizes much of the SDE processing engine (eg. 
SDE based clipping, RDBMS expressions). This leads to 
very non-general code and potentially confusing
configuration. SDE is sort of special in this case. I'm
leaning to using SDE simply as another datasource,
relying on mapserver functions to project, clip, classify and query. I believe consistency is important
and I really don't want to change the rules for
different data sources.

Understanding that MapServer expressions are ripe for
optimization and expansion (eg. functions), how many
users would this decision impact? Given that a full 
SDE implementation hasn't been out there anyway I would
hope not many.

Have a good new year...

Hi,
   I just installed mapserver from a nightly build with PHP4 support,
GDAL v1.1.1, TIFF, etc.

I have PHP using mapscript and can call on the files from the mapserver
demo, but I need to access some .tab files.  I created a new .map file
to use the files that I am testing with.  I contains (roughly)

# Start of Map File
NAME City
STATUS ON
SIZE 600 600
UNITS METERS
SHAPEPATH "data"

LAYER
	NAME country
	STATUS DEFAULT
	CONNECTIONTYPE OGR
	DATA canada.tab
END


But I am getting a blank image file.  

Any Suggestions.

With CONNECTIONTYPE OGR or SDE, the "DATA" and "SHAPEPATH" parameters
are ignored.  You have to use the CONNECTION parameter instead.

For OGR, the CONNECTION parameter value should be the path to the data
file relative to the location of the .map file:

LAYER
        NAME country
        STATUS DEFAULT
        CONNECTIONTYPE OGR
        CONNECTION data/canada.tab

Message-ID: <01010309305500.26273@churup>

Hello there!

MapServer run great! But there is still some questions i asked me.

I would like to know if MapServer support Opacity (or transparency) for 
shapefile. I mean, i have a region shapefile over a geotiff and i would like 
to see the tiff under region (which is opaque)

Also, when you zoom in the raster, it become very pixelized and since openev 
blur the raster when you zoom in and it use gdal, i was wondering if 
MapServer can do that.

And with the projection, some of them make segfault mapserver (like Boggs 
Euphormic) and some take years to render (like Mercator or UTM). I mean 
years, cause i never seen the rendered map!!

And at last, i have seen a post to how to use OGR with .tab, but i lost the 
post... (i use kmail instead of mailx now... :-)). I did that so far:

LAYER
  NAME test
  STATUS ON
  CONNECTIONTYPE OGR
  DATA data/W80w56N63n45.tab
END


Sorry for the bad english and thanks a lot!

Fred

Joel,

The location of the php_config.h file has changed in PHP 4.0.4 and the
configure script could not find it.  I have updated the configure script
and you should be able to compile PHP/MapScript using tomorrow's nightly
build (or today's CVS source).  

Other than that, PHP/MapScript seems to work well with PHP4.0.4 for me.

Good Luck!

You could use a symbol to fill your polygons, and by playing with the
density of the symbols, then you can control the level of opacity. 
We've done that before and it gives very cool results... I think it was
using a dot symbol but I'm not sure... Email me directly if you need
more details.

Actually, MapServer does not use GDAL yet... but we'll add it sometimes
in the next few months.  BTW I don't think it's GDAL that does the
blur in OpenEV... Frank W. can probably confirm that.

I attached a simple .map file that loads a canada.tab file in lat/lon
coordinates... it works well with the test_draw_map.phtml script that
comes in the mapserver/mapscript/php3/examples directory, assuming that
you've compiled OGR into your php_mapscript.so, of course.

Note that the resulting map will be very ugly... but it at least shows
how to use OGR in MapServer!  :)

Good Luck!

Hello All!

Ok, calling all raster gurus out there: I've got a problem I hope someone can help me with!

I've got a bunch of USGS DOQs (both in BIL and jpeg(COQ) format) I'd like to display in a couple of different ways: 1. I'd like to be able to create a raster layer and display an individual DOQ (COQ) in jpeg format, and 2. I'd like to be create a shapefile to tile a series of DOQs(COQ), again in jpeg format (say, a township or county). Unfortunately, I've not had any luck with either. 

I have created world files for these (which I'm not 100% confident in), using Todd Poston's qdir extension. I'm also wondering if I should be using a projection scheme here, but I'm not familiar with using projections in mapserver, or with proj4. At any rate, I've still got something broken, and am unsure how to proceed.

I've been searching the archives for others who have attempted this, and have found bits and pieces (so I guess it's possible), but I think I am still missing something (the first clue was no images displaying...). I was hoping some kind soul would be gracious enough to walk me through the steps necessary to make these scenarios work.

If anyone can help me out with this, I'll fedex my right arm this afternoon.

Here's a little Avenue script that will build the tile theme for you.  It
will add all the images in a view to the theme, and assign the image's
filename (without directories) to a 'Source' field in it's table.


'--Start Script
theView = av.GetActiveDoc
theFN = FileDialog.Put("imgtile.shp".AsFileName, "*.shp", "Save Image
Tiles")
if (theFN = nil) then return nil end
theFTab = FTab.MakeNew(theFN, Polygon)
theFTab.AddFields({Field.Make("Source", #FIELD_CHAR, 64, 0)})
for each theTheme in theView.GetThemes
  if (theTheme.Is(ITheme)) then
    theNewRec = theFTab.AddRecord
    theFTab.SetValue(theFTab.FindField("Shape"), theNewRec,
theTheme.ReturnExtent.AsPolygon)
    theFTab.SetValue(theFTab.FindField("Source"), theNewRec,
theTheme.GetSrcName.GetFileName.GetBaseName)
  end

Subject: Bundling mapserver data in image comment
Message-ID: <Pine.GSO.4.21.0101031859330.13352-100000@homer>


Hi,

I'm using an applet wrapper to provide the interface to mapserver, and am
passing data values from mapserver to the client through an html
template. For example, [img] and [mapext]. This means that every
interaction with the server requires two queries, one to get this data and
one to download the image. Setting mode=map could reduce this to one
query, but I can't compute the new extent on the client side because it
depends on several mapfile parameters that are not necessarily uniform
across different uses of the client applet. 

I thought that a way to optimize this could be to pack the necessary data
such as map extent into the image comment. This way the image and data
could be retrieved with a single query, since Java applets can access
image comments. I think JavaScript can too. Mapserver doesn't provide
direct support for this, but with the number of mapserver applications out
there that use Java and/or JavaScript wrappers, I think this would a
feature that could provide excellent performance improvements:

* Single HTTP query for single logical map operation.
* No need to read and write a temporary file.
* Don't need to periodically clean out temp image directories.
* Less load on server.
* Less load on network.

Presumably we would need an IMAGETEMPLATE field in the Web object, that
points to a file containing template variables and whatever else. I'm not
sure what the character limit in GIF comments are, or if TIFS or JPEGS
allow comments.

Please let me know what you think,

Keith.

Subject: Can't get Zoom Factor persistent
Message-ID: <OF158B48A0.F393350A-ON852569C9.00725DE0@er.usgs.gov>

I am working on an interface that uses radio buttons to choose zoom in /
zoom out / pan / query and a SELECT list to choose the zoom factor.  I have
been able to more or less get the radio buttons to stay persistent, but I
am having trouble with the template file substitutions for the zoom factor.

The substitution [zoom_2_select] always returns "".  (Same goes for zoom_4
and zoom_8.)   I think I am just a little confused on the syntax of the
subs.  I looked at previous posts but still couldn't get things working.

Also, is there a list of all the CGI variables that MapServer understands?
I just realized that the Template File Reference lists the variables that
MapServer returns and subs into the HTML of the template file,  but these
are not necessarily the same as the variables passed to MapServer when a
form is submitted.  (For example, you can submit a form variable called
"zoomsize" to Mapserver but it doesnt return a variable "zoomsize" to the
template file when it is done.  I am wondering if there is a comprehensive
list of the form variables that can be submitted.)

My application is at:
http://sun4dilurb.er.usgs.gov/cgi-bin/mapserv?map=/export/home/mjhoffman/public_html/gage.map
and the template file is
http://sun4dilurb.er.usgs.gov/~mjhoffman/gage.html


Thanks a bunch,

Hi,

It is more of an ESRI question than a MapServer question. However, I can't find
any hints in ESRI archives, so I hope I can get some help here. I have ArcView
GIS only, have you guys seen any ArcView extensions or 3rd party software that
can combine several adjacent shape files into one shape file?  And is there a
performance difference for MapServer to use several smaller shape files or one
single larger shape file? Thanks.

Hi all, 

We're trying to query a layer using a mapscript queryUsingPoint.
According to the documentation this finally (via queryResultObject and
shapeSesultObject)
returns a Shape. How can we retrieve the attributes (fieldvalues)
belonging to this shape.
Are there mapscript methods to accomplish this, or is this to be done

Gert-Jan,

Yes, you have to use PHP's dBase module to access the attributes.  Also
important to note is that PHP dBase record numbers start at 1, but
MapScript's shape indexes start at 0, so when you read your DBase
record, you have to use:

  $rec = dbase_get_record_with_names($db, $result->shape+1);

See also the function GMapDumpQueryResults() in gmap75.php3 in the GMap
PHP/MapScript demo for a complete example of dumping attributes of
selected shapes.

Have you tried XTOOLS ?

http://gis.esri.com/arcscripts/details.cfm?CFGRIDKEY=4D4DBAEA-25DA-11D4-942E
00508B0CB419

MERGE is one of the tools provided with XTOOLS, here is the Instructions
that come with it:

Instructions For Merge Themes:

MERGE creates a new theme by combining selected features from an input theme
with selected
features from a user-specified list of merge themes.  In either theme, if
user selects
no features, all features are selected.  The output theme contains all
selected features
from the input and merge theme(s). MERGE does not intersect features.  Each
selected
feature in the input and merge theme(s) is maintained as a separate entity
in the output
theme.  Input theme features can be points, multipoints, polylines, or
polygons.
However, all merge themes must have the same feature type as the input
theme. In other words,
you can not use Merge Themes to combine themes with different feature types.

Feature tables are also updated. Attributes of the input theme are
maintained in the output
theme.  Each selected shape in the merge theme(s) will have one record in
the output theme.
Attributes of the merge theme(s) will be transferred to the output theme,
for those fields
that have names and field types that match a field name and type in the
input theme.

MERGE automatically updates Area, Perimeter, and Acres fields present in a
polygon output theme and
updates the length field in a polyline output theme.  If these fields are
not present in the output
theme, the fields are automatically added to the output theme and then
updated.

Script by Mike DeLaune, (Email: mike.g.delaune at state.or.us), Oregon
Department of Forestry, 10/30/97.
Edited 7/28/98.

Requires:  At least two Fthemes in a View with the same feature type.

Instructions:

1. Add some themes to the view.

2. If any features in the input or merge themes are selected, Merge
will be applied to the selected features. Otherwise, merge will be
applied to all features in the theme.

3. Select the Merge Themes menu option.

4. In the first dialog box, select the input theme containing
the fields that you want to preserve in the output theme.

5. In the second dialog box, select the theme(s) from the view
that you wish to merge with the input theme.

6. In the third dialog box, you will be asked for an output shapefile name
for
the new theme.

The DNR has several examples:

Serves Landsat (processed to 8-bit), DOQ, DRG and even
county plat maps.

  http://www.ra.dnr.state.mn.us/

Features several interfaces using Landsat (and soon
SPOT) imagery. The biggest issue is the need for pre-
processing imagery to fit within the 8-bit confines
of the GD image library. Despite that the results are
most often very useful and popular.

Sorry Alex, I've never encountered that problem. I poked around
your site a bit and I didn't see anything which looked untoward.
This message is cc'd to the list in case somebody else there
has an idea. 

Listers: Alex's .map file can be viewed at http://64.0.86.237/demo.map
I initially thought the problem might be with %tmp% permissions,
but you can load each of the images directly if you know their
name (eg. http://64.0.86.237/tmp/DEMO978622390204.gif; View Source
on demo.html and grab the names from the IMG tags). I'm stumped.

Message-ID: <3A558992.65109E10@gaf.de>

Does anyone have experience with using a Progress database for the
attributes besides the geometries stored in shape files? I am thinking
of using MapScript and the Perl DBD::ODBC module in combination with
some kind of ODBC driver (Merant?) to join the attributes of the
Progress database to the shapes. If someone has experience, which ODBC
driver do you use and are there other Perl modules, which I could use?
Is the general approach correct?

Thanks a lot,

Subject: Access map-file via php/mapscript
Message-ID: <3A55A584.7112FECD@webgis.de>

Dear List!

We are using MapServer/PHP-Mapscript under Linux. A few days ago I
downloaded the MapServer-Win-Binaries and the newest
PHP4-MapScript-DLL's and installed them on a Win98-Labtop with Apache as
webserver.

Under win MapScript shows up as an extension in the php_info-page.
Everything's fine so far... but I am not able to access any map-file!

Under linux I did:
$map = ms_newMapObj("/home/schulzm/mapserver/fr/fr.map");
everything worked fine. Under win I changed it into
$map = ms_newMapObj("c:\programme\mapserver\fr\fr.map");
causing PHP to crash. I tried to use relative pathnames and started the
php-script from the directory where fr.map resides:
$map = ms_newMapObj("fr.map");
then i get a Mapscript error: 'MapServer Error in msLoadMap(): (fr.map)
in c:\programme\mapserver\fr\ms_fr.php on line 10'.

Hmm? Could anyone give me a useful hint on this newbie problem? TIA

In the Mapserver homepage, it says that one can create
a Python mapserver module using the Perl one... How do
I do that?

Michael,

I don't think that's the source of your crash, but in PHP, you should
escape the "\" character in your filename (just like in C or Perl):
   $map = ms_newMapObj("c:\\programme\\mapserver\\fr\\fr.map");

But again I don't think this is the reason for the crash... MapScript
must have found the file and crashed while it was loading it.

This error message suggests that MapScript could not locate fr.map...
but it should have found it since you placed it in the same dir as the
ms_fr.php script... so it must be something else then?!?


Which version of PHP4 have you installed on your computer?  The
PHP4-MapScript DLL on our web site is compiled for PHP4.0.3pl1 ... so if
you installed another version of PHP4 (e.g. 4.0.4) and replaced your
php.exe with the one that was in the ZIP on our site, then that could
quite well explain the crash.

Please get back to me directly with info about your PHP4 config and
we'll see what we can do.

Hi dear mapserver users,


Does anyone have experience in selecting features by making a query command?
Is this possible?

For example:

I like to select all companies which are within 200 meters from the railway

Is this possible with mapserver?

Everything seems to be working fine. But the map and

I've compiled it with gd 1.2, and with gd 1.8, but the

Message-ID: <3A560C87.C1A456F4@noaa.gov>

MapServer users (and developers) - I'm in the position to recommend
using various internet mapping applications.  I'm most excited about
MapServer, but I have to be practical, so I have some questions that I
thought some of you might be able to answer.  Steve Lime probably could
address all of these, but perhaps others could help?

1)  Currently, MapServer is limited to 8 bit imagery.  The home page for
GD says that full color image support will be available in version 2.0. 
How long will it take to incorporate that capability into MapServer? 
(And I'll have to ask the GD folks when 2.0 is coming...)

2) I'm currently working on a project to serve up imagery over the Web. 
I know that some of you have had success connecting MapServer to ArcSDE
for vector data - are there any success stories or plans for future
integration with raster data?  (I know ArcSDE is a little shaky on
imagery, so I don't expect a lot now...)

3) What are the future plans for MapServer?  If the NASA funding dries
up, or Steve Lime decides to retire, what happens?  Is anybody committed
to picking up the lead if he goes away?

That last question was not for me, but for my manager, who does not
share my confidence in open-source software.

Thanks!

We are going to add support for the GDAL library in MapServer in the
coming months.  I don't think this will give access to SDE rasters, but
it will add a bunch of formats... http://www.remotesensing.org/gdal/

We (DM Solutions Group) have and continue to invest quite a bit in
MapServer and OpenSource software in general and we would likely be
there to keep MapServer alive if that was to happen.  Of course, 
what you suggest won't happen (nobody would want that!)... but since 
you asked.  :)

I think an equally pertinent question is will mapserver support open
standards for interoperable Web Mapping - the OpenGIS Web Map Server
standards. Wrappers are possible but native support would be better.

http://www.opengis.org


This has been mentioned a few times over since release of the specs in April
2000.

Think support for the OGC standards for interoperable Web Mapping is a very
important direction.

	I think an equally pertinent question is will mapserver support open
	standards for interoperable Web Mapping - the OpenGIS Web Map Server
	standards. Wrappers are possible but native support would be better.

Good questions Mike,

I have some of my own I would like to add:

Some of you may remember my earlier questions and summary 
about ArcIMS vs Mapserver:
http://mapserver.gis.umn.edu/cgi-bin/wilma_hiliter/mapserver-users/0011/msg0
0143.html

There were two points brought up which were clearly in 
ArcIMS's favour which could not be easily addressed or 
dismissed.

1) Distributed servers and failover architecture: ArcIMS
is designed for a multiserver hosting environment, fetching
data from any server and passing it on to the browser, and
other related sercives/technologies.

2) Serving vector data as well as images:
http://x67.deja.com/getdoc.xp?AN=696207202&CONTEXT=978725920.1488191528&hitn
um=0
Do note though that I did not find a site taking advantage
of this functionality though I was assured some do exist.

Now I know Mapserver and ArcIMS are answers to different
questions and solutions to different problems, they just
happen to share significant overlaps. What I'd like to
know is, is Mapserver content with it's current problem 
domain? (serving images of maps to browsers, displaying 
selected database records)

I'm particularily interested in using a Mapserver-like
interface/tool-set to serve data, not just pictures of
data. It would be a a year or two before our particular
shop could use or implement it, but I do see it as being
increasingly more important. Just like XML is becoming
more important (read: useful) than html.

The OGDI protocol addresses this, but there is not yet
an Open Source solution, or even a good closed source
client... anyway, that's a sidetrack at the moment.

I'm not asking Mapserver developers (ie: Stephen) to
tackle this montrous job. I would just like to know if 
this area has been thought about, and if the architecture
of Mapserver allows a "plugin" data server, should such 
a beast ever be developed, by UMN or anybody else.

cheers,

We agree (mainly). As now stated on the MapServer Home page that work is underway 
(and of top priority).

See the Map Notes section in the lower right of each map to
know what scale you need to zoom to.

Subject: MapServer Workbench version 0.3
Message-ID: <20010105210543.43420@nyx.net>

I've updated my MapServer Workbench.  Grab the latest copy off my web site
at: http://www.nyx.net/~tpoindex/gis/

The list of changes is attached below.  Most notable is support for
Windows.  I have also submitted some changes to Steve for building the
Mapscript/Tcl interface, which is required by the Workbench.  (You can run
msedit.tcl without Mapscript.)  The updates to Mapscript/Tcl are some
configure/Makefile changes, plus all of the Makefiles to build Mapscript
for Windows.

I'm planning to move my development tree (probably to SourceForge), and I 
should have a Windows DLL to distribute at that time, hopefully in a few 
days.  In the meanwhile, Unix users should download and build an updated 
version of Mapserver and Mapscript/Tcl from the 'nightly' CVS build from the 
Mapserver home pages.

README.1st:
MapServer Workbench

release 0.3, January 5, 2001


You should treat the MapServer Workbench as beta quality software.  I haven't
done extensive testing on a wide variety of mapfiles.  Please report bug
and enhancement request to me.  Or feel free to fix bugs and send me
patch files :-)

In particular, you should make copies of mapfiles, html, and datafiles
that you intend to use with the Workbench.  

The *.tcl files are quickie installs using /usr/local/bin/wish8.3.
You should probably use the 'install.sh' script if possible.

Until MapServer 3.4 becomes a stable release, expect MapServer Workbench
to lag behind the latest changes.  This may mean functionality that works on
one 'nightly' MapServer release may break something here on the next release. 

Known bugs:  (many more unknown ones, probably :-)
-msappwiz.tcl: Only 'plain' HTML files are in the template directories.  If
 you pick 'Javascript' or 'Java' enhanced pages, the program will fail.
 


Fixes/changes since last release:

msedit     - added custom icons for tree view for each map object
	   - fixed adding objects twice to parent object
	   - changed to use tree control -user data to hold map mstclobj's
	   - added shortcut keystrokes to invoke functions	
	   - added support for windows: startup & dde to other msworkbench tools	   - removed some prompts when saving to same file name
	   - copy old file to backup when saving

msexplorer - remove per window config structure, just use one config
	   - added shortcut keystrokes to invoke functions
	   - added support for windows: startup & dde to other msworkbench tools	   - fix View menu functions for zoom out, pan, query
	   - write temp gif files to tmp directory
	   - remove prompt when quitting and opening new files

msshapex   - added shortcut keystrokes to invoke functions
	   - added support for windows: startup & dde to other msworkbench tools	   - remove prompt when quitting
	   - add menu to pick a label attribute when viewing shapefile
	   - fix arc shapefile type viewing
	   - new button to clear retrieved records

msappwiz   - added support for windows: startup & dde to other msworkbench tools	   - don't allow backtracking after file generation
	   - tweaks to mapfile generation: scalebar, legend, etc.
	   - don't re-create other map objs on regeneration
	   - redraw reference image on regeneration
	   - remember directory path when gathering data files

setup.tcl  - windows installer, uses dde interface to program manager to
	     add a program group and items, thanks Steve Cassidy for the
             dde code to talk to program manager.

etc.

Ok,

I didn't want to make it public before some of our customers see that as prime time. But here is what can be done with MapServer and a lot of midnight oil. As usual I cannot release this stuff for free. We must decide what can be given back to the community.

Basically, the raster is JPEG (tricked with some gd improvements) and the green lines are roads built with very simple map files. The rest is proprietary. It has some features like quad-tree indexing ... very useful for snapping .. No doc, no help, just prototype.

It issues the big question : where is the standard to transfer vector data from server to client ? XML ? GML (not really appropriate).

Please be gentle with this poor PII450 with a 128 Kb line. Don't save too much. Saving the changes works. About sharing data ? Not with shape files for sure but with some DB like Frank (W) would like to set up. Next step.

Here is the url : http://195.115.79.18/goose/java/goose.html

Expect loading about 120Kb of data at 128 kb if you are alone on the server. It takes some time with a 56 kb modem. It takes about 2 mn for first load. 

Marc

Subject: getting [mapetx] from item/value searches
Message-ID: <20010107130725.21488.qmail@web4301.mail.yahoo.com>

Hello again...

I'm trying to set up a site with mapserver in a way
that, after an item/value search, I can navigate
pan/zooing.

I've noticed that when I ask for (in example) some
city
(http://.../mapserv?map=...&item=place&name=Matatu&qlayer=...),
the [mapext] expands into the mapext of the map that
is rendered when I call mapserv with the mapfile, and
no other arguments.

Why that? shouldn't the item/value pair mean the same
as any other ways of telling the coordinates that we
want displayed? like mapxy/scale...?

Anyways, I saw the "searchmap" attribute in the CGI
reference, and it seems to be exactly what I want. but
it didn't work
(http://.../mapserv?map=...&item=place&name=Matatu&qlayer=...&searchmap).
The map displayed is just perfect, but the [mapext]
keeps turning into the old map's mapext...


How do we get the new mapext in an item/value
search????


thanks!!

Subject: Compiling MapServer on SuSE 7.0
Message-ID: <103975657.978896246521.JavaMail.servlet@wm01>

Dear List,

I?m trying to compile MapServer with php support on suse 7.0.
I have configured php 4.0.4 with the following Options.

'./configure' '--with-mysql' '--with-apache=/home/nicol/programme/apache_1.3.14'
'--with-xml' '--enable-track-vars' '--with-gd=/home/nicol/programme/gd-1.8.3' '--with-zib'
'--with-ttf' '--mandir' '--with-packages' '--with-ftp' '--with-jpeg-dir' '--with-xpm-dir'
'--enable-bcmath' '--with-system-regex'

In the next step i run the configuration Script from mapserver with the latest sources from cvs (07.01.2001) with the following parameters

./configure --prefix=/usr/local/mapserver --with-gd=/home/nicol/programme/gd-1.8.3
 --with-tiff --with-jpeg --with-eppl --without-ttf  --with-php=/home/nicol/programme/php-4.0.4 --with-apache=/usr/local/httpd

This proceedure finshed without any errors. Whenever i run the make script it crashes with the message below

yacc -p msyy -d -omapparser.c mapparser.y
usage: yacc [-dlrtv] [-b file_prefix] [-p symbol_prefix] filename
make: *** [mapparser.c] Error 1

I?ve no idea which problem causes that error. Does anybody out there has the same problem and could give me a hint to this newbie problem?
yacc is installed and working fine.

Thanks a lot
Nicol

I suggest you to use OpenGIS WMS as I am using in my client:

http://opengis.jrc.it

Between my servers and my client I don't actually transfer vector-
data, but using MapServer, I convert it to GIF images. In that
way the transfer gets much faster. The OpenGIS WMS protocol
as it is implemented in most prototypes until now does it
like that, but it also forsees to actually transferring vector
data. To get more information about WMS look here:

Subject: proportionnal symbols
Message-ID: <3A599C56.85903076@dial.oleane.com>

Hi,
I practice Map Server for a couple of days, and find it very performant to display maps.
Our need is to put statistical datas on the map. I began to use CLASS object to change the color.

When it is to display rates, it is ok. But when I want to display for example the number of olympic successes at Sydney 2000, the proportionnal symbols is the best, as we did it at http://www.makeyourmap.com/Sydney2000 .

Is it possible to display a symbol directly proportionnal to the data without using the class object (which will give the same size for many different values).

I could not find any information in the doc and no sample in the gallery.

Thanks

Kleith,

Seriuosly, how can you edit vector data as GIF images ?? With SVG or CGM you may, I agree with plug-ins. The prototype shows that editing is possible but only by transfering vector data to the client. And when compressed  (in this case of 250 fields) it represents only 50 Kb.

dear sir,
i've used Mapserver V3.0.11 and the newer for several months. I modified 
gdft/dfttf.c to support GB2132 Chinese code and rebuilt mapserv.exe. it works 
well. Now i tried php/mapscripts dll, it works if using the win32 binary 
php3_mapscript.dll (built using php-3.0.14). i have to rebuild the dll to 
support chinese GB code, but i can't find php-3.0.14 source. so i tried 
php-3.0.16, php-3.0.17, php-3.0.18, php-4.0.1pl2, php-4.04 to build the 
mapscript dll, but the dll can not be loaded by php program. The size of the 
dll i built (using php-3.0.16/17/18) is 1,134,661 bytes, the dll binary 
(using php-3.0.14, which can be loaded successfully by php) size is 1,130,564 
bytes. i don't know the differnces between php-3.0.14 and php-3.0.16. Are 
there some people can help me how to build php/mapscript.dll? where can i get 
the php-3.0.14 source? how can i use php-4.0.4 for php/mapscript?

Does your development effort (GDAL support etc) add functionality to the
entire MapServ executable or just to your PHP extension?

It IS possible: Each time the user wants to have something changed in his client a
request is made to the server to send an updated map. This may seem less
effiicient, but to my experience it is much faster, especially with big vector-
datasets (yours, with 50kB is rather small, I have datasets with several
MBs, which is not unusual). But even in your case, GIF images created
from vector data tend to be very small, so we could assume it would be
only 10 kB per requested image. This means that your user could request
5 times a modification to his map to have the same "cost" (in Bytes) as
transferring your 50 kB vector dataset to your client!

The php-3.0.16 source should do... we used it before without any
problem.

You write that your DLL refuses to load.  Do you get any error message?
Any warning in the apache error_log file?  Does it make PHP crash?

One important thing if you've modified the GDFT stuff is to make sure
that your PHP is not compiled with TTF support because then you could
have a conflict between MapServer's GDFT files and PHP's GDFT.

I could get you a copy of the php-3.0.14 source, but as I wrote above
the 3.0.16 source should be OK.  About php-4.0.4, it is even trickier to
compile on Windows than PHP3... so I suggest that you stick with PHP3
for now.

Please send me any error message you get and we'll see what we can do. 
(Probably a good idea to Email me directly to avoid bugging the list
with boring windows build details!)

1) I'd have to see the new GD 2.0 API to know how hard the port will be.
I've isolated GD related code intentionally for such port and mapfiles already
take 24-bit color so it shouldn't be a bit deal. However, I been inquiring about
GD 2.0 for 5 years now and it's still not out so I wouldn't hold my breath.

2) MapServer currently supports TIFF/GeoTiff, ERDAS and EPPL7. Condional
PNG/GIF/JPEG support is already there as well. Images can be tiled. There is
a plan to use GDAL instead which should only add to supported formats. SDE
image support can be added if ESRI publishes the API which I haven't seen yet.

3) While NASA supports some MapServer development they certainly aren't 
covering it all. It has become a hobby. While I'm not planning retirement you 
never know when you might get hit by a bus. The user group and the University
need to comment on that event. There are commercial interests in the system
which can only help with it's long term viability.

The best way to deal with this is by encouraging use and expanding the number 
of developers. There are 3 with CVS write access and a couple of others contributing 
code. That group needs to expand a bit. Once 3.4 is release that may be a good time 
to reasses.

MapServer users (and developers) - I'm in the position to recommend
using various internet mapping applications.  I'm most excited about
MapServer, but I have to be practical, so I have some questions that I
thought some of you might be able to answer.  Steve Lime probably could
address all of these, but perhaps others could help?

1)  Currently, MapServer is limited to 8 bit imagery.  The home page for
GD says that full color image support will be available in version 2.0. 
How long will it take to incorporate that capability into MapServer? 
(And I'll have to ask the GD folks when 2.0 is coming...)

2) I'm currently working on a project to serve up imagery over the Web. 
I know that some of you have had success connecting MapServer to ArcSDE
for vector data - are there any success stories or plans for future
integration with raster data?  (I know ArcSDE is a little shaky on
imagery, so I don't expect a lot now...)

3) What are the future plans for MapServer?  If the NASA funding dries
up, or Steve Lime decides to retire, what happens?  Is anybody committed
to picking up the lead if he goes away?

That last question was not for me, but for my manager, who does not
share my confidence in open-source software.

Thanks!

1) MapServer can certainly be used in a multiserver environment. The ability is not built
into the core program (not sure it is with ArcIMS either) and would need to be handled
using load balancing hardware/software and some mirroring software to keep the sites
in sync. It certainly can, and has been done. I posted a perl script based on some stuff
written by Chris Stuber to balance mapping across a small server farm. Worked great.
You just don't have those admin tools out-of-the-box as with ArcIMS. Perhaps someone
wants to work on such.

2) As part of WMT compliance I'm planning to support vector serving using GML in addition
to raster outputs. One goal I have is to make the DNR Data Deli a full participant (serving data,
images and metadata) of the ESRI Geography Network. This can only be done with WMT and
would make us probably the only non-ArcIMS participant.

I think MapServer has already moved beyond simple map making and record retrieval. MapScript
and PHP/MapScript really allow for a whole new class of applications and utilities to be written.
Most users (including myself) haven't even scratched the surface there. Productivity apps like
Tom Poindexter's MapServer Workbench really are going to help open things up to a broader
audience.

Good questions Mike,

I have some of my own I would like to add:

Some of you may remember my earlier questions and summary 
about ArcIMS vs Mapserver:
http://mapserver.gis.umn.edu/cgi-bin/wilma_hiliter/mapserver-users/0011/msg0 
0143.html

There were two points brought up which were clearly in 
ArcIMS's favour which could not be easily addressed or 
dismissed.

1) Distributed servers and failover architecture: ArcIMS
is designed for a multiserver hosting environment, fetching
data from any server and passing it on to the browser, and
other related sercives/technologies.

2) Serving vector data as well as images:
http://x67.deja.com/getdoc.xp?AN=696207202&CONTEXT=978725920.1488191528&hitn 
um=0
Do note though that I did not find a site taking advantage
of this functionality though I was assured some do exist.

Now I know Mapserver and ArcIMS are answers to different
questions and solutions to different problems, they just
happen to share significant overlaps. What I'd like to
know is, is Mapserver content with it's current problem 
domain? (serving images of maps to browsers, displaying 
selected database records)

I'm particularily interested in using a Mapserver-like
interface/tool-set to serve data, not just pictures of
data. It would be a a year or two before our particular
shop could use or implement it, but I do see it as being
increasingly more important. Just like XML is becoming
more important (read: useful) than html.

The OGDI protocol addresses this, but there is not yet
an Open Source solution, or even a good closed source
client... anyway, that's a sidetrack at the moment.

I'm not asking Mapserver developers (ie: Stephen) to
tackle this montrous job. I would just like to know if 
this area has been thought about, and if the architecture
of Mapserver allows a "plugin" data server, should such 
a beast ever be developed, by UMN or anybody else.

cheers,

-matt

GDAL support will be an optional component of the MapServer core, just
like SDE and OGR are right now.  So it will work with the mapserv CGI
and all flavours of MapScript.

mapserver is likely simply defaulting to the extent that is defined in your 
mapfile.  To get it to do otherwise, use either the "buffer" or "scale" keywords 
in your query.  Eg.:

http://.../mapserv?map=...&item=place&name=Matatu&qlayer=...&scale=100000
or
http://.../mapserv?map=...&item=place&name=Matatu&qlayer=...&buffer=5000

These types of buffer queries are not supported at the moment. You could accomplish
this using MapScript however. For example you could:

1) select all with beer sales permits
2) calculate distance from company to railway

MapScript has several distance computation (simple euclidan) methods available for
point and shape objects. There may be even other ways to accomplish this but I'll have
to think about it a bit more.

Hi dear mapserver users,


Does anyone have experience in selecting features by making a query command?
Is this possible?

For example:

I like to select all companies which are within 200 meters from the railway
station and have a permit to sell beer.

Is this possible with mapserver?

This type of problem is generally either:

  - data location problem (i.e. mapserver can't find the shapefiles and the 
    INGNORE_MISSING_DATA flag was included at compile time)

Check for those first.

The yacc parser probably won't work with the mapserver grammar. You should've recieved
a mapparser.c file in a regular or nightly distribution. Was it missing or did you download directly

be in good shape.

In the next step i run the configuration Script from mapserver with the latest sources from cvs (07.01.2001) with the following parameters

./configure --prefix=/usr/local/mapserver --with-gd=/home/nicol/programme/gd-1.8.3
 --with-tiff --with-jpeg --with-eppl --without-ttf  --with-php=/home/nicol/programme/php-4.0.4 --with-apache=/usr/local/httpd

This proceedure finshed without any errors. Whenever i run the make script it crashes with the message below

yacc -p msyy -d -omapparser.c mapparser.y
usage: yacc [-dlrtv] [-b file_prefix] [-p symbol_prefix] filename
make: *** [mapparser.c] Error 1

I ve no idea which problem causes that error. Does anybody out there has the same problem and could give me a hint to this newbie problem?
yacc is installed and working fine.

Thanks a lot
Nicol

Subject: proportionnal symbols
Message-ID: <sa59b4de.017@smtp.dnr.state.mn.us>

There is no current way to pull symbol size from an attribute column (although under the
new 3.4 architecture it will be easy to add). You have a couple of options. You can obviously
use CLASS objects to change symbol sizes as you would colors. You could vary both if you
wanted based on multiple items, that might result in a large number of classes which could
be tough to manage. Is there any reason CLASSes won't work? Looking at the example you
sent that would seem to be the ticket.

The other option is to develop maps using MapScript were you have total control. You could
easily modulate symbol size by an attribute value on a feature-by-feature basis. For moderate
sized datasets this wouldn't be that inefficient.

Hi,
I practice Map Server for a couple of days, and find it very performant to display maps.
Our need is to put statistical datas on the map. I began to use CLASS object to change the color.

When it is to display rates, it is ok. But when I want to display for example the number of olympic successes at Sydney 2000, the proportionnal symbols is the best, as we did it at http://www.makeyourmap.com/Sydney2000 .

Is it possible to display a symbol directly proportionnal to the data without using the class object (which will give the same size for many different values).

I could not find any information in the doc and no sample in the gallery.

Thanks

Dear Morissette,
Thank you very much for your help. I finally find the php-3.014 source and complied with mapscript/php3. The size of the php3_mapscript.dll (i rebuilt using php-3.014)  is also 1,134,661 bytes, but it works. I'm very happy to see the result. I'll modify some source to support GB2132 Chinese code (The original mapserver only supports UTF8 and Big5 code). I've tried IIS4, Apache and iPlanet. Mapserver is very efficent. It is faster than MapXTreme Java V3.0 and ArcIMS V3.0. Our company will try to use MapServer for logistics application (add some network analysis module). Most of our apps are composed of JSP. I wander if mapserver can support JSP.  
thx.

Subject: Win32 builds with OGR, PHP3, and PHP4
Message-ID: <3A5AB145.736C48FE@dmsolutions.ca>

There seems to be an increasing number of people who attempted to
compile custom versions of MapServer and PHP/MapScript on Windoze
without success recently.  Unfortunately, building Win32 executables
is not very friendly, and you are strongly encouraged to use the
pre-compiled binaries if you can.

There are win32 binaries for the last stable release (3.3.011) and the
latest nightly build on the MapServer web site at:
  http://mapserver.gis.umn.edu/win32binaries.html

And for those who need one of OGR and/or PHP, the win32 binaries on our
site were getting quite out of date, so I have placed 2 updated
packages:

mapserv.exe, and MapScript for PHP3.0.14:
http://www2.dmsolutions.ca/mapserver/dl/ms_3.4pr-win32-ogr-php3-20010103.zip

MapScript for PHP 4.0.4:
http://www2.dmsolutions.ca/mapserver/dl/php4.0.4_mapscript_dll-20010108.zip
(should be used with the php-4.0.4-Win32.zip found at http://php.net/)

In both cases, the binaries include the following options:
    - MapServer 3.4 (pre-release)
    - GD_1_2 
    - PROJ.4
    - FreeType
    - TIFF 
    - EPPL7
    - OGR

Enjoy!

As I read the error message and the yacc-manpage the problem seems that
yacc can not handle the -o option ?! By default yacc would generate
something like y.mapparser.c

Nicol, since bison is also in the SuSE 7.0 distribution you should
install the package. If the error still occurs, check the 
variable YACC in the top makefile and set it to "bison -y" if necessary.

Hello Steve, list,

I personally think that using SDE as a data processor might have some
advantages. Although I never did any programming using the SDE API myself I
think that there is a lot of functionallity in it that would be very nice to
have access to. We are thinking about using MapServer and ArcSDE to serve a
large amount of data over the net. This data should be accessed by users
using RDBMS and locational queries. Anyway, I did not yet get to play some
more withg it to get a deeper understanding on how map server and SDE work
together - so maybe I am not yet in the position to give a fully qualified
comment on this.
I would also like to know if there are any plans on providing access to the
Oracle Spatial Data Object datatype.

OK, let's see if I can beat the record of newbie
questions!


Why don't img.x/y  work when whe call a map using
mapxy/scale pair instead of mapext?

the map i'm calling with mapxy and scale is comming
perfectely, but when I use mapxy, scale and img.x/y,
the resulting map points somewhere near the guinea
gulf (arount the 0,0 point!)

I know you may not have the answer. Probably it's jut
another stupididy  of mine, but writting helps a lot!

Subject: mapxy and scale with img.x and img.y
Message-ID: <sa5af46b.027@smtp.dnr.state.mn.us>

img.x and img.y (or imgxy) imply the use of an input image, that is, the user
is clicking in an image. In order to turn that click into a coordinate you need
image size and the extent of the image that was clicked in.

mapxy with scale/buffer implies you're NOT using an input image. If you don't
supply the imgext parameter (which defaults to -1,-1,-1,-1) you'll end up with 
some interesting results.

Bottom line: mapxy with scale/buffer and mapext are useful for initializing an 
application or using the software as an image/query engine. Img.x/y or imgxy etc 
are necessary when doing interactive apps. Be careful mixing the approaches.

Steve

The 2 techniques are mutually exclusive, with img.x/y taking precedent.

There may be some specialized support for certain functions (i.e. buffer) if SDE
is available. In that case we'd replace my code with ESRI's. Otherwise I guess
you'd want to write an SDE only application. MapServer will use SDE for spatial
(eg. envelope) queries and limited attribute query.

The new code base will give a programmer a short list of functions he/she will
have to write to integrate a new data source with the MapServer. Under that
scenario it should be easy to add Oracle Spatial support. I myself am not in a
position to do that since I don't have that software. I'll gladly help the person(s)
that wish to add that support though.

Steve,

You can get a free developer version of Oracle (including Spatial) if
you register at http://technet.oracle.com/ (500MB download)

We have done some work with the Java SDO API and may be able to help a
little too if someone decides to add Oracle Spatial support in
MapServer.

Subject: Shading polygon shapes by joining to MySQL
Message-ID: <3A5E1369.4E9B8583@keyspanenergy.com>

Hello All,
I'm trying to put all the pieces together, but am surely making little
headway.

I've set up a .map file that enables me to render Zip Code polygons. I
can also shade the polygons using REGEXP expressions.
All of this I'm doing with a basic mapserver forms-based app and the
mapimage.class applet. I thought I could join the Zip code's .dbf file
to another .dbf file and shade the polygons based on one of the fields
available via the join. I then discovered that you can't do this... (if
I read the mail archives right).

The platform I'm on is NT4.0, PHP Version 4.0.3pl1, MapServer Version
3.3.012, MapScript Version (Nov 01, 2000) and MySQL.
All are working. I also downloaded the DM Solutions gmap demo package
and, aside from the query items portion, it's working just fine. (Nice
app, Dan! But, way too complicated for my Intro to Mapscript!)

The goal I'm looking for would require, I think, mapscript and php,
since I'm on NT.

I'd like to show zip code polygons (like I'm doing now), but allow the
user to select an attribute from within the MySQL db. eg: Render the Zip
Codes from the existing zipcode shape file, and shade them based on the
results of the db call. I can get my web-hands on all the data for this
via Perl, cgi, web forms, etc. but the rendering has got me stopped in
my tracks.

Can anyone point me toward an example site that can accomplish such a
feat? I don't think it's far-fetched. I just can't figure a way to
combine these 2 pieces of functionality.

As always, thanks for any assistance.

Kieran

I've started a project at SourceForge to keep my MapServer Workbench.
Also, since I have more web space available, there is a package of
Mapscript/Tcl that contains a Windows DLL, needed to run MapServer
Workbench under Windows.  (you still need Tcl/Tk installed.)
Screenshots also available to see what you're missing if you haven't yet
tried the tools. 

I don't yet have the files under CVS due to some 'technical difficulties';
that should be fixed soon.  I would still prefer to use this mailing
list for feedback on the tools, rather than the SourceForge lists.

As a first step, we have used the shptree-Tool, and it

Are there any additional tools or tips You can tell me

Daniel's advice is sound  - for now, don't install the Workbench in a

unpack the archive in C:\msworkbench, or similar until I get this 
fixed.

Message-ID: <02fe01c07ccd$1d5abe40$6f6c2ec0@yardarm.nohrsc.nws.gov>

Displaying query results in a new window --

Using javascript you can set the target object in the form.  This can allow you to change the output of a form submission to either a new window or a new frame.  In order to do this, you need to be careful to reset the form target for other functions so that you are not constantly sending stuff to new windows.  To see how this works, go to:
http://www.nohrsc.nws.gov/mapserv/ms_refmp/

The page automatically redirects you to one of two versions depending on your screen size -- if you have a small screen, query results will display in a new window, if you have a large screen query results will display in a frame on the right of the screen.  All the scripts I used can be seen using the view source option in your browser.  I handle all form submissions through JS so I simply set the form target in each of my functions to make sure everything gets directed to the right place.

Any questions, drop me a line.

Thanks for the bug report.  This should have been a warning in the README,
I'm only supporting GIF at the moment, mainly due to how I'm bulding
MapscriptTcl & the fact that GIF support is included in base Tcl/Tk; JPG,
PNG, etc. require the Img extension.  I put those extra images types
in the app builder, but I should make them inactive for now.

I'll need to figure out away to find out what which GD lib Mapserver is 
compiled with, and offer only those same choices.  

I'm also CC'ing this to the list, it's probably useful to others.

Also of note, I'm keeping track of bugs at the sourceforge project page.
Feel free to submit bugs there also.

Alex,

I'm thinking that your problem is that you might be using the png version of
the mapserver executable. The java applet doesn't support the png image
format so download the gif version of the exe and see how you go. Otherwise
it is most likely a path problem. You can check if mapserver is actually
creating the images in the temporary directory that you have specified.

I am currently finishing off a new version of the utility. The old one
wasn't really set up to deal with WinTel environments. I just need a few
people to help in the testing. Any volunteers.

Ross

Hi,

I like to find out if mapserver CGI support this:

display objects based on specific DBF information?

As an example, DBF file contains a field named ObjectID. And, a map being
displayed has bunch of lines in it. When user zoom into the map, all lines
that fall inside the bounding rectangle will show up. Is there a way to tell
mapserver to draw only those lines that match the given ObjectIDs?

The same question applies to mapscript. Can I just pass these lines
ObjectIDs to some mapscript functions, and it will only plot these lines?

If mapserver cgi or mapscript does supports the above functions, can I get
some examples to get me started?

Thanks.

Hi,

Is there a way to turn off/on labels associated with objects through mapserv
CGI? I know that you can set the LABELMAXSCALE to control the labels, but
can you specifically instruct mapserv CGI to do that by passing parameters
to it? Or, maybe through mapscript?

These labels are LABELITEM in LAYER object defined in mapfile.

An alternate approach I have in mind is to put the labels on a separate
layer than the objects. But, if I can keep it the way it is (ie. same
layer), it would be a better solution.

Thanks.

Dieter,

I tried your script and .map file using PHP3 and recent versions (about
1 week old) of MapScript on Linux and Win98, and in both cases it passes
the classes part, but returns the following error:

Fatal error: MapServer Error in msDrawMap(): Image dimensions not
specified. in ex1.phtml on line 16

... that's because your .map file is missing important parameters like
EXTENTS, SIZE, and a WEB object.

However, I don't think that explains your crash... because "Document
contains no data..." means that the server crashed without generating
any output.  How old is your PHP/MapScript DLL (or .so) ?  It might be a
good idea to get a more recent one... either compiling the latest
nightly build on Unix, or if you're on Windows there is a recent
precompiled PHP3_MAPSCRIPT.DLL that you can download at 
http://www2.dmsolutions.ca/mapserver/dl/ms_3.4pr-win32-ogr-php3-20010103.zip

BTW, setting colors the way you did in the classes would not give the
expected results... the color parameter in a class object in a .map file
is the RGB value, but in MapScript it is a color index obtained from
addColor().  So the following lines in your script:

> $poClass->set("color",255, 0, 0);
> $poClass->set("outlinecolor",255,0,0);
> 

Should be replaced with:

  $poClass->set("color", $map->addColor(255, 0, 0) );
  $poClass->set("outlinecolor", $map->addColor(255, 0, 0) );

Good Luck!

Alexandre,

You don't have to compile it yourself... just download a precompiled
binary from http://mapserver.gis.umn.edu/win32binaries.html
it contains a file README.1st with installation instructions.

Hi Daniel,
thanks a lot, I got the nightly built and compiled them - now it is working.

I was using the 3.3.011 -Version (that is the most recent one on the web-site
instead of the nightly built ones.)

Thanks for the tip with the colors!

Dieter

Message-ID: <01011610303303.01101@n20908j>

Hi there,
this do not work....


$poClass = $poLayer->getClass(0);
$poClass->setExpression ("8125048");

this is the error-message:
Fatal error: MapServer Error in getSymbol(): (8125048):(63)



it's running when I set it up in the map file like this:

CLASS 
       NAME test
       EXPRESSION "8125048"
       COLOR 0 128 0 
END # end of class object

I'am able to change with mapscript the colors of this class, but I can't change
the expression.

I'm using LINUX, and the latest nightly-build sources. (with php3).

Any ideas?

Dieter

Subject: PHP_Mapscript install errors

Dear Daniel and others,

I do not seem to be able to get mapscript running.

--> system AIX 4.3
--> Apache 1.3.14
--> PHP 4.0.4pl1
--> Perl see below for the Perl -V specification

I get an error message called : make: 1254-002 Cannot find a rule to create 
target = from dependencies.
Stop.                    

In my opinion you grep the necessary flags, but as I know AIX is not the 
most 
compatible platform. Does anyone have an answer?

Regards,

Peter

Hi,

Any idea why I can't see any images when I run the mapserv demo?

I get the correct test output:
http://www.smartcanuk.com/cgi-bin/mapserv  gives me:
No query information to decode. QUERY_STRING is set, but empty. 

(http://www.smartcanuk.com/gis/demo.html)

regards,
Dan Bertrand

Subject: formatting numbers
Message-ID: <sa64206a.094@smtp.dnr.state.mn.us>

MapServer internally treats everything as a string so that's what's coming from
the xbase code. May be dependent on the number of decimals allowed for that
attribute. One way would be to filter the MapServer output through JavaScript,
for example in your template:

<script language="javascript">
  var nfarms = [nfarms];

  ... code to format the value of nfarms ...
  document.write("Number of Farms (1987): " + nfarms);
</script>

Or something similar. Let me think about it a bit more. It's likely that a modification
to DBFReadAttribute() in mapxbase.c specific to floating point columns would have
to be made.

I haven't seen any questions about this:

Is there a way with Mapserver to change the format of the numbers
brought back from a query on an attribute?

All my numbers get displayed in scientific notation like:

Number of Farms (1987): 2.200000E+02
Acres of Land in Farms (1987): 2.793700E+04
Percent of County as Land in Farms (1987): 7.399501E+00
Acres of Land in Farms (1982): 3.215600E+04

Thanks,
Andrea

This is what class objects are for. You can use class expressions to
restrict display to certain sets of features or to change the display 
characteristics (eg. color/size/symbol) for each "class". I've attached
a map file that I use to draw different highway shields based on an
item value. Look at the definitions for "major_roads".

Hi,

I like to find out if mapserver CGI support this:

display objects based on specific DBF information?

As an example, DBF file contains a field named ObjectID. And, a map being
displayed has bunch of lines in it. When user zoom into the map, all lines
that fall inside the bounding rectangle will show up. Is there a way to tell
mapserver to draw only those lines that match the given ObjectIDs?

The same question applies to mapscript. Can I just pass these lines
ObjectIDs to some mapscript functions, and it will only plot these lines?

If mapserver cgi or mapscript does supports the above functions, can I get
some examples to get me started?

Thanks.

The problem is that the demo was written for 3.3.011 with the old symbol format and
you're using the new source code. I thought there was a demo based on the new
code already available. Anyone?

I think my question was a bit unclear. I need to be able to tell mapserv
which object to display based on what a user has selected at runtime. So,
it's like I need to change the CLASS EXPRESSION in the mapfile at runtime,
telling mapserv what to display, based on user selections.

Say, on a page, we will display a list of all objects that are currently
visible (I think we can do this through other methods. Users can then select
the objects they want to display, and click on Refresh to display a new map
containing only those objects being selected (hiding the ones that are not
selected). Say the user selected objects with ObjectID=1, and ObjectID=5.
You would tell mapserv to only display objects with these ObjectIDs. And, at
the same time, user can zoom in/out, and the list of objects will change.
Users can then modify their selections in the same manner.

>From what I understood, CLASS object EXPRESSION is static.....only those
objects that matched the EXPRESSION get displayed, and the selections of
objects get displayed don't change at run time.

Thanks.

No, you can change the value of EXPRESSION at runtime. It's easiest within
mapscript where you simply use the class method setexpression but you can
do it with the CGI version too. There's an example of this at:

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

Basically you need to masage the user input into a valid MapServer class
object expression. It's usually necessary use javascript. Then you use the
syntax available in cgi.html on the main MapServer site to change the
expression dynamically. If you have a single class then create at hidden
variable:

  <input type="hidden" name="map_mylayer_class_expression" value="">

Then at the appropriate time (either form submission or when a control is
mucked with) use javascript to set the value for that hidden variable to
something like:

  /^id1$|^id2$|^id3$|.../ for regex or
  ([ID] = id1 or [ID] = id2 or [ID] = id3 or ...) for logical expressions

A regex assumes a value for CLASSITEM whereas a logical expression
does not. Clear as mud?

it's like I need to change the CLASS EXPRESSION in the mapfile at runtime,
telling mapserv what to display, based on user selections.

Say, on a page, we will display a list of all objects that are currently
visible (I think we can do this through other methods. Users can then select
the objects they want to display, and click on Refresh to display a new map
containing only those objects being selected (hiding the ones that are not
selected). Say the user selected objects with ObjectID=1, and ObjectID=5.
You would tell mapserv to only display objects with these ObjectIDs. And, at
the same time, user can zoom in/out, and the list of objects will change.
Users can then modify their selections in the same manner.

>From what I understood, CLASS object EXPRESSION is static.....only those
objects that matched the EXPRESSION get displayed, and the selections of
objects get displayed don't change at run time.

Thanks.

This is what class objects are for. You can use class expressions to
restrict display to certain sets of features or to change the display
characteristics (eg. color/size/symbol) for each "class". I've attached
a map file that I use to draw different highway shields based on an
item value. Look at the definitions for "major_roads".

Hi,

I like to find out if mapserver CGI support this:

display objects based on specific DBF information?

As an example, DBF file contains a field named ObjectID. And, a map being
displayed has bunch of lines in it. When user zoom into the map, all lines
that fall inside the bounding rectangle will show up. Is there a way to tell
mapserver to draw only those lines that match the given ObjectIDs?

The same question applies to mapscript. Can I just pass these lines
ObjectIDs to some mapscript functions, and it will only plot these lines?

If mapserver cgi or mapscript does supports the above functions, can I get
some examples to get me started?

Thanks.

There are two win32 packagings of Mapserver (assuming you are using the
binaries from http://mapserver.gis.umn.edu/win32binaries.html
<http://mapserver.gis.umn.edu/win32binaries.html> ), one with GIF support,
and one with PNG support.
 
The demo is setup for GIF support, if you have the PNG version of Mapserver
you will get errors like you describe. So you can either: 1) download the
GIF version of Mapserver or 2) change the Demo to work with PNGs.
 
2) Download "gif2png.exe" from http://exe2bin.com/gif2png-win32/
<http://exe2bin.com/gif2png-win32/> .
-Put gif2png.exe in a directory searched by %path%
-change to the ms_demo directory (cd d:\maps\ms_demo)
-batch convert all GIFs to PNG from a command shell (may only work in NT):
    d:\maps\ms_demo> for /r %a in (*.gif)  do gif2png -Op %a
-replace all refences to .GIF to .PNG in the following files: *.html,
demo.map, symbols\*.sym

Hi,

more question....

Is the function like in the map-file 

$poClass->setExpression('[NAME]" == "Test");

not available? I ask, because that would be great to change things comming out
of mysql (to set for NAME a variable and for the string a variable...)

Is it possible to negate an search, like:

$poClass->setExpression("[NAME]" != "Test");

Thanks.

I have a hacked-up 'demo_012.map' in the test directory, included with
MapServer Worbench, along with a 'newsym.sym' symbolset file.  You
should be able to drop these two files into the existing demo files and
get it to work with the new mapserver.

Or, just use 'msappwiz.tcl' to generate your own demo :)

Hello All,

I've come a bit further on the AIX problems, but now get the 
message on my 
browser : php_mapscrtipt.so doesn't seem to be a php library

The problems I encounter are:

--> First of all the makefile script of php_mapscript says : no 
rules to make 
target. This can be solved to comment the line
CFLAGS := $(CFLAGS) $(MS_DEFINE) $(MS_INC) $(PHP_INC) I just 
include these on 
top of the mapfile at the CFLAGS command. Are there people who 
experienced 
the same problems?

-->I furthermore had to recompile both Apache as PHP to include 
the 
EXTRA_LDFLAGS. This seems to work OK, so I don't think this is 
the problem

--> I couldn't just at the perl.exp, because it didn't had a 
path.

Regards,

Peter

Peter,

I think I've seen that message before, it happens if PHP cannot find the
module's entry point in the .so: get_module()

Make sure your php_mapscript.so does include the get_module symbol:
 
   # nm php_mapscript.so | grep get_module

It it's not there, then it may be that php_mapscript.c was not compiled
with -DCOMPILE_DL defined... but it seems to be there in your makefile.


About your Makefile problems, could you try using GNUmake?  That may
help.  Of course, it would be better if the PHP Makefile did work with
AIX's make, but I don't have access to an AIX system to test it, so at
least until it can be fixed you would be able to compile your module.

Peter,

In your reply you write

  nm ./php_mapscript.so | grep get_modules

but you're looking for get_module with no 's' ... can you double-check
that?

I really don't know what else to suggest... hard to tell without having
an AIX box to try stuff!

Has anyone else tried and/or succeded in compiling php_mapscript.so on
AIX ???

Installing on OpenBSD should not be difficult (works well on
FreeBSD) as long as you have the correct libs installed
(most of which should be available via ports).  You may have
to tweak the linking stage if you plan on using the PHP
interface, though.

Hi,

I hesitate to call myself even a newbie (is there such a thing as a wannabee newbie), but from what I can tell mapserver looks like it would really be useful for some projects I have in mind.  I've looked at the demo and I can get some help from our computer support folks for installation, but it would really be valuable for me if I could see mapserver in action and talk with someone first.  

With this in mind, is there anyone in the Washington, DC/northern VA area using mapserver that I might come and visit?

The output html page works fine with the [xlayer_check] hook, but the

I tried making the 'allnone' checkbox name "layer" and value "allnone", with 
a [allnone_check] hook, but no luck.  Perhaps this does not work because it 
is not a layer?  How can the mapserv app interact with this?

Any suggestions?

Thanks

1.
Is there a way to define the data of a shapefile shown on the map by
using an attribute query? I want the user to log in and show only the
information he is allowed to see, i.e. setting a query definition to the
shapefile(s) with mapscript. Does anyone have an example for this?
2.
For large datasets I assume it is faster to work with tiles, is that
correct? Can I combine working with defining the shown data by a query

A couple of problems that I have run into when using MapScript with PHP3.

1. When doing a query on a map with multiple layers, the result of a
msqueryUsingPoint() only returns the shapes in the first two layers and
seems to ignore the other layers on the map.  I have a nice tolerance so
that all the layers have some shape where I click but only the first two
layers respond.

2. When I am trying to find the scale that I am currently at on the map
when zooming, the $map->scale returns -1.

Any help would be greatly appreciated.

Thanking you in advance.

I guess you could use classes for this. That is, assuming there is an owner attribute
for each shape you could add to the normal class expressions "... AND '[OWNER]' == 'user'".
You then have to build those expressions assuming you have multiple users. Couple of
ways to do that depending on how anal you are about security;

 - use CGI vars to change expressions dynamically
 - use mapscipt

The next version of MapServer will allow you to substitute CGI vars directly into expressions
so you could write "... AND '[OWNER]' == '[CGI_OWNER]'" where CGI_OWNER is a
variable in your HTML form. MapScript gives you the most control obviously. You could
build user specifc mapfiles as needed. That way you could store user data in separate
shapefiles. You also have access to a richer set of authentication schemes.

Very large datasets are more efficient in tiled format, for the most part. Expressions are
supported on tiled shapefiles. Normal query (by point, area or rect) is not supported (yet!)
on tiled shapefiles. Coming soon though.

Folks,

I have available for download compiled MapServer binaries with GDAL support.
It hasn't been tested yet so I haven't added a link to it from the Win32
binaries download page.  However, if anyone would like to test it, it can be
downloaded at

http://mapserver.gis.umn.edu/win32bin/ms34gif_gdal_nightly.zip for GIF
output and

http://mapserver.gis.umn.edu/win32bin/ms34pmg_gdal_nightly.zip for PNG

If you do test it, please let me know (and maybe the list) if it works,
works well, or if it doesn't work at all.

Thanks.

Subject: mapimage.java public method addition?
Message-ID: <F116lnVHa9fyMFHtGeo00000dfd@hotmail.com>

Hi,

I have implemented the wonderful mapimage applet into my web mapping 
application.

A feature that I would like to add (or see added) is an X Y report of where 
the user's mouse is over the mapplet.  Using the X Y position of the mouse 
over the image, one could access this from javascript, ie.

<APPLET
CODEBASE="/gis/mapserv/tom_demo/mapimage"
CODE="mapimage.class"
WIDTH="600"
HEIGHT="400"
NAME="mapimage"
ONMOUSEOVER="javascript:mapOver();" MAYSCRIPT>

<!-- does ONMOUSEOVER in applets work in NN?? -->

<PARAM NAME="image" VALUE="192.168.1.3[img]">
<PARAM NAME="jitter" VALUE="1">
<PARAM NAME="color"  VALUE="255 0 0">
</APPLET>

Note ONMOUSEOVER.

Then, through a public method within the .java file, ie:

public int[] reportXY(Event e, int x, int y) {
  int [] XYCoords;
  XYCoords = new int[2];
  XYCoords[0] = x;
  XYCoords[1] = y;
  return XYCoords;
}

..then in the javascript:

function mapOver() {
// grab image width/height
  var re = / /;
  var imgsize  = [imgsize];
  var newarray = new Array();
  newArray     = imgsize.split(re);

  // grab user X and Y click pos from java public method

  var tmpxy = new Array();
  tmpxy     = document.mapimage.reportXY(); // arguments here?

  var tmpx =  Number([minx] + (tmpxy[0] * (Math.abs([minx]) - Math.abs 
(([maxx]))) / NewArray[0] ));

  var tmpy = Number([miny] + (tmpxy[1] * (Math.abs([maxy]) - 
(Math.abs([miny]))) / NewArray[1] ));

  document.mapserv.mapOverX.value = tmpx;
  document.mapserv.mapOverY.value = tmpy;
}

...thus updating the form boxes.

Does this sort of thing make sense?  Has anyone tried this, or an 
alternative?

I've tried this but can't seem to find out the how to get the XY out of the 
applet.

If I could get this going, I'll post the edited source to the group with 
examples.

Thanks for your time.

..Tom

Looks like a problem with the binary tiff file reader. There are just darn many tiff
flavors it's tough to test them all. I don't have time at the moment to work out the
bug. It's probably simple and is located in mapraster.c in the tiff reader if anyone
wants to take a shot. I'll fix in the next release which is my main focus at the moment.

The workaround is to convert to greyscale, 4-bit or 8-bit. I know the loss in compression
will create much larger files. Hopefully you don't have too many or can convert just a
few for development.

Pericles,

I downloaded and gave a quick try to the ms34gif_gdal_nightly.zip and it
seems to be working OK with MapInfo TAB files.

BTW, I know all these acronyms make things very confusing, but I have a
small clarification to make for the benefit of all users: you talk about
GDAL here, but I assume that you meant OGR, which is part of the GDAL
source tree... GDAL and OGR share some code and are part of the
same source code package, but are 2 different things:
  - GDAL is for raster file formats
  - OGR is for vector file formats
and at this point, MapServer only supports OGR's vector file formats...
(unless someone added support for GDAL's raster formats recently?).  

Thanks a lot for making this available!

Robert,

We've tried to keep the PHP version of MapScript as close as possible
to the original MapScript (in Perl).  But there are indeed
differences, and the main reason is that the Perl version of MapScript
is produced using SWIG, but since PHP is not supported (yet) by SWIG
then we had to implement all the PHP wrappers manually.

Also, because of the way things (like objects) work in PHP3, there are
some things that had to be adapted from the original MapScript to make
the wrappers usable, like using set() methods to set member variables. 
Anyways, it's a long story, but I'm sure you'll get the idea.

> Secondly, what stage of development is PHP MapScript currently at?

I would call is stable... or "permanent beta" would probably better
describe what happens with a piece of software like MapServer that keeps
getting better and better but never really freezes.  PHP MapScript 
should be in sync with the main MapScript version in Perl.  If you're
aware of anything missing then please let us know.

Again, PHP MapScript is just a set of wrappers on top of the same C
functions that are used by other flavours of MapScript... so what works
with Perl/Tcl/Python MapScript should work with the PHP version too.
If you could send to the list specific examples of the problems that you
ran into then that could certainly help us in helping you.


Humm... I guess I should have asked that at the beginning, but which
version of MapServer/MapScript are you using?  Several things have been
improved/fixed since 3.3.011, the nightly builds since the end of
December are probably better than version 3.3.011 was back in July.  If
you're still using 3.3.011, then I suggest that you get a recent nightly
build.

Best Regards,

Robert,

This probably has more to do with your .map layers setup than with
MapScript itself.  Are all the layers you want to query with STATUS=ON,
and do they all contain a QUERY object?

We've used queries with multiple layers before and I don't remember
noticing a problem... but a bug is always possible.  If you're sure that

I've made a few tests and also noticed that $map->scale is sometimes set
to -1 before any call is made to an operation that forces recomputing
the scale, like calling $map->zoompoint() or $map->setextent().

Once again, if you could isolate the problem and send me a piece of
script that reproduces the exact case that you're refering to then
that could help a lot in reproducing and fixing it.

Subject: database access
Message-ID: <3A6E8C74.FD9D38D0@gaf.de>

I tried to find out what is possible with combining MapServer
(MapScript) with databases by looking throught the archive but it is
still difficult to me to get an overview. I am new to MapScript so I
just want to know if the things are possible I want to do before
spending too much time on it. There are two things I would like to do:

1. Access attributes in a database by a spatial query (query by point,
polygon...)
2. Display maps based on a classification on the attributes in a
database

Is this possible using MapScript and Perl (DBD Module) or is there a
better aproach?
Sorry if this is something already discussed, but I am still not sure
about this and would really appreciate some help. Perhaps there are some
examples on this somewhere?

Many thanks,

Matthias

I'm not familar with the maplet, but I can tell you a bit about java. You
could extend MouseMotionAdapter to capture the mouse position. The general
idea would be like this:

public class PointLabeler extends MouseMotionAdapter {
    public void mouseMoved (MouseEvent  e) {
       // get the position in pixels relative to java's default origin at
the top left corner of the innermost component containing the mouse position
       int x = e.getX();
       int y = e.getY();
       // translate position from java coordinates to map coordinates

      // display label
   }
}

Let me know if you need more help.

You folks might want to consider patching a newer version of the mapimage
applet rather than the one Tom is mucking with. It uses the newer mouse
API and may be better suited to this modification. See attached...

Subject: zooming in a query window
Message-ID: <3A6F550E.FC0C20F2@geoplan.ufl.edu>

A little while ago I asked a question to the list about how to
show scanned images using a point shapefile representing their location.
With Steve's help I have it sort of working. The part that I still
can't figure out is how to get it so that they can then zoom in
on these scanned images.

To see what I mean, take a look at:
http://map2.geoplan.ufl.edu/mapserver/start/thememaps.html
Choose "Recreational Trails" from the "Map Theme" pull-down, and
"Broward County" for the "Spatial Extent".

Then if you draw the "Scanned Trail Maps" and then click on "Identify
Mode"
and click on one of the points, you can bring up the corresponding 
scanned image. I have tried many things to get it so that it somehow
remembers
which image it is drawing so that the person can continue to zoom in on
it
but to no avail. 

Any help with this would be appreciated.

Thanks,
Andrea

Message-ID: <F82xtAEHLB8TrBHxvZ900002533@hotmail.com>

Steve,

Thanks alot for the upgraded code.

FYI, here's what I added to mouseMoved:

public void mouseMoved(MouseEvent e) {
  int x = e.getX();
  int y = e.getY();
  // javascript function
  window.eval("mapOver('" + x + "','" + y + "');");
}

..then, the javascript function mapOver:

function mapOver(x,y) {
  document.mapserv.mapOverX.value = Number([minx] + (x * (Math.abs
([minx]) - Math.abs(([maxx]))) / getMapSize('width')));
  document.mapserv.mapOverY.value = Number([maxy] - (y * (Math.abs([maxy]) - 
Math.abs(([miny]))) / getMapSize('height')));
}

(getMapSize is a js function to split [mapsize] to get the image height and 
width.  Can I get to these through the CGI params without parsing in 
javascript?)

Probably could be *alot* cleaner, but it works, provided there is a mapOver 
function defined in the HTML.

Joan, thanks alot for the Java tip.

..Tom

Hi,

I've downloaded the latest nightly version from mapserver website.
I wonder if i can specify the output map from mapserver to be in jpeg
format, since i use it from a java applet.
I've compiled mapserver with USE_GD_1.8, compiled gd to get jpeg support
and add "imagetype JPEG" in the mapfile, but that didn't work since the
output map is always in png format...

Any help will be aprecieted.

Robert,

I haven't played much with querymaps and I'm not sure what's the best
way to do what you ask, I don't think there is a direct way to "zoom to
selected objects", but I may be wrong.  

I guess one possibility would be using the shapeFileObj to open your
layer, and read the extent (getExtent(i)) of all selected objects... and
then use that to set the map extent.  Requires a bit of coding, but that
would work... 

Hopefully someone on the MapServer list will know a more straightforward
method (using either Perl or PHP).

Good Luck!

Message-ID: <NDBBLDJBFKFMCHCLKNJFKEFECBAA.yeewen@petromap.com>

Hi,

I've implemented something similar to Case #3 in
http://maps.dnr.state.mn.us/mapserver_demos/tests/itemquery/test.html
but the user query by dragging a box with the mouse over a map to query
objects. I display a query result and result map in a popup window.

Anyway, I noticed this behaviour:

If I set the STATUS of the layer I'm querying on to be OFF, the result map
doesn't show up. If STATUS is set to DEFAULT, the result map shows up.

My problem is that I have to set the LAYER STATUS to OFF in order to be able
to turn layer on and off.

Does anyone has any idea on how to resolve this problem? ie to get both
(query result map and layer on/off) to work?

Here's my mapfile, ywseis.map, showing only the layer that I query on.

Hello from New Zealand everyone!

The function Robert has requested seems like an essential component for an 
online GIS.  For instance, it would enable address finding - where the user 
types in an address and the map is rendered and presented, highlighting the 
selected property. Very useful (and important). This signals a bigger issue 
for me.

I am a relative newcomer to MapServer and the OpenSource movement. While 
MapServer is impressive as it stands, I know there's a lot of good 
development work being done by many people.  There seems a large risk that 
effort may be being duplicated.  Is there a register somewhere which 
identifies who's working on certain aspects of Mapserver, Mapscript etc, or 
forthcoming release notes?  How do we ensure wheels aren't being 
re-created?

For instance, I would like to know what Java interfaces have been developed 
for Mapscript on Linux.  Where could I find this info?

I look forward to being part of the MapServer movement, and contributing to 
making online GIS affordable to the mainstream.

The function Robert mentions is part of the MapServer
CGI (mapext=shapes). Since MapScript essentially allows
you to rewrite the MapServer CGI program to meet your
own requirements that function needs to be written by
the user at the moment. We can add it to the "to-do" 
list for MapScript though.

Source developers, admittedly a small group at the
moment, keep in touch all the time. I'm assuming you're
refering to those building apps. The main way to not
reinvent the wheel is to use this list and POST the
applications you're working on.

I also hope that the MapServer documentation project
will minimize duplication. The project consists of the
main website documentation, and a proposed series of
"how-to" documents that would cover a wide variety of
topics from installation to specific java/javascript
tips and tricks. The UMN has recently hired a 
documention and user support specialist to help this effort. Stay tuned...

This list will continue to be an integral part of 
support and development so please use it!

identifies who's working on certain aspects of Mapserver, Mapscript etc, or 
forthcoming release notes?  How do we ensure wheels aren't being 
re-created?

For instance, I would like to know what Java interfaces have been developed 
for Mapscript on Linux.  Where could I find this info?

I look forward to being part of the MapServer movement, and contributing to 
making online GIS affordable to the mainstream.

Mapserver users - We're in the midst of planning a project here dealing
with raster data analysis.

I wrote a quick (read: cheesy) C routine that counts the pixels in an
image that have the value X.  I can (and probably will) extend this to
be able to get some subset of that image and count the pixels in that
subset.  This all should be easy.  My users, however, would like to see
all of the pixels inside of a particular polygon (shapefile).  There is
an article on the web talking about various solutions to the
"point-in-a-polygon" problem - 

http://home.earthlink.net/~bobstein/inpoly/

and just stealing that code looks pretty easy.

What I am more uncertain about is the process of extracting all of the
nodes (is that the right word?) of a shapefile polygon and passing them
to one of these "point-in-a-polygon" routines.  Does the mapserver
source code include a routine that would make this simple, or is there
other stuff out there to simplify this process?

I have a fairly short amount of time that I'll be allowed to devote to
this process, so the easier the better.

Thanks!

MapServer has a point-in-poly routine that was adapted from code in the
comp.graphics.algorithms news group/FAQ. The code is short and sweet.
I added a wrapper to account for islands and multiple parts. The source
is in mapseach.c. The algorithm considers only inside/outside and is
ambiguous on edges. Since we're not dealing with exact input it's not
an issue in processing queries from a web user. For more information:

You should also note that raster data query and analysis capability is a 
focus of the TerraSIP project's enhancements to MapServer. To see a couple 
examples: <http://terrasip.gis.umn.edu/projects/egis/avhrr/>, 
<http://terrasip.gis.umn.edu/projects/egis/knn/index.html>. The hooks for 
this are in the MapServer distribution (I believe). We can make the 
additional code available to anyone who asks.

Subject: using pieces of mapserver code
Message-ID: <3A7452B4.D79F6E80@bellsouth.net>

This is almost a C programming question, but I don't know of any groups
to which I could address the question other than this one.  Here goes:

I am a so-so C programmer, who has never really undertaken any large C
programming projects.  I understand C syntax (for the most part), but I
get confused when I have to include multiple source files, particularly
those written by other people.  I'm trying to get started in
understanding how some of the various useful functions in the mapserver
source code work.

For example, I'm trying to compile the code included at the bottom of
this message, and I keep getting 'undefined reference to X' messages. 
In Java (for example), if you want to use one method from a particular
class, you just import that class, and the compiler grabs all of the
classes that class depends on, and so forth.  I think it's not exactly
that, but the point is from the programmer's standpoint it is easy.  

Is there a utility for C that allows you to build the appropriate
makefiles without chasing down all of the necessary functions in all of
the source code?

Or, could I use (or make) a library out of the C code that is in
mapserver and use that?


Thanks!

As already mentioned in a reply to your earlier question (accidently not
cc'd to the list :( I suggest to have a look at the shapelib
http://gdal.velocet.ca/projects/shapelib/index.html
on which the MapServer shapefile read-in is based.

Frank - I will include some of the errors which I am seeing below, but I
believe I understand the problem, which is that I am not including all
of the subroutines that support the one function I am trying to use. 
I've tried various things, including the line below, gcc -o test
mhtest.c *.c, and a perl script to include all C routines in the
mapserver directory and all of it's subdirectories.  I know these are
somewhat amateurish attempts to grab all of the routines necessary, but
the issue is one I have never been able to resolve:  

How do you include all of the subroutines your program depends on,
without including all of the subroutines you do not depend on, and
without iteratively increasing the files you refer to in your command
line compile or makefile?

Is this the role of configure or some related program?

If you are familiar with perl - have you already thought about
implementing the required application using the mapscript feature of
mapserver?

No. AFAIK this is something the linker does. The crude version: 
There is a static library libmap.a in the mapserver directory 
after sucessfull compilation. A static library is an archive of 
object files providing some functionality. In mapserver case there
are imore than 20 files collected in the lib. If you use this 
lib, the linker takes the required objects out of the archive ....

However, there might be some dependencies outside the lib.

again libmap

you should compile the mapserver an than apply something like

gcc -o test -lmap -lgd mhtest.c

(given the required include files / libs are in your search paths)

Hi,

I've downloaded the latest nightly version from mapserver website.
I wonder if i can specify the output map from mapserver to be in jpeg
format, since i use it from a java applet.
I've compiled mapserver with USE_GD_1.8, compiled gd to get jpeg support
and add "imagetype JPEG" in the mapfile, but that didn't work since the
output map is always in png format...

Any help will be aprecieted.

Message-ID: <sa755d8c.067@smtp.dnr.state.mn.us>

So if I understand correctly you want to have a separate little mapserver app
to browse the scans correct, and this is totally unrelated to the main application.

To do this I would create a separate mapfile to handle the image browsing. That
mapfile would likely have only a single layer, the scanned image. What you need
to do is control the "DATA ..." parameter so you can make it specific to each 
particular image. You can do that with a CGI variable like this:

  <input type=hidden name=map_imagescan_data value="someimage">

where the value of someimage is pulled from the location point shapefile initially. The
query file for the points and the template for image browsing will look almost identical
except in the way some variables are initialized. In the query template you'll pull
the image name and perhaps some extent/size information and in the browse template
you'll use cgi pass through (to remember which image) and normal mapserver
replacements for imgext and so on. Here's how to maintain the image:

  <input type=hidden name=map_imagescan_data value="[map_imagescan_data]">

This really isn't too hard once you see how things fit together.

A little while ago I asked a question to the list about how to
show scanned images using a point shapefile representing their location.
With Steve's help I have it sort of working. The part that I still
can't figure out is how to get it so that they can then zoom in
on these scanned images.

To see what I mean, take a look at:
http://map2.geoplan.ufl.edu/mapserver/start/thememaps.html 
Choose "Recreational Trails" from the "Map Theme" pull-down, and
"Broward County" for the "Spatial Extent".

Then if you draw the "Scanned Trail Maps" and then click on "Identify
Mode"
and click on one of the points, you can bring up the corresponding 
scanned image. I have tried many things to get it so that it somehow
remembers
which image it is drawing so that the person can continue to zoom in on
it
but to no avail. 

Any help with this would be appreciated.

Thanks,
Andrea

Here is how it is knows which image to draw (this is in the Recreational

Robert,

There is no queryUsingExpression() call... but you might be able to
achieve the same result if you set the expression in the query object of
the layer, and then use queryUsingRect() with a rectangle the size of
the map.  I've never done it, but that should work.

I wanted to add that this is what itemquery is turning into in the next release. Dan's
suggestion is a good workaround for the moment.

Hello All,

I haven't been very diligent about keeping up on this, so I'll just ask:
speaking of the next release, is querying tiled data going to be available?
That would be really great if true!

Thanks

Yes, query of tiled data (and SDE and OGR) will be in
the next release. Some major changes were made to 
facilitate queries across the board which is why it's
taking so long. I'm testing shapefiles and tiled
shapefiles now and should be commiting the code this
week. Then SDE and OGR still need to be brought up to
date.

This may have something to do with the fact that MapServer does a
chdir() to the directory where the .map file lives... so if your 2 map
files live in different directories then that could explain what
happened.  There may also be other global things that I am not aware of.

BTW, your questions should be sent to the mapserver-users list... that's
what it's for.  You will also have more chances of getting the right
answers, and others will benefit from the answers too.

Subject: Mapserver question
Message-ID: <3A76DF4B.B1672AB2@starss.net>

Hello,

I'm currently evaluating MapServer for an upcoming project.  I have been
impressed with it thus far.

It appears that Mapserver will do everything we want it to do with one
possible exception.  Is it possible to dynamically generate map layers
based on databased data?
For instance, if we have users input an arbitrary location and
corresponding data, then store that data in a database, is it possible
to represent the location on a layer with a point. 

I am guessing that this is the void ArcSDE will fill, but need to make
sure that this feature is/is not available now. If this is the case, any
rough estimate on when the MapServer extension for ArcSDE will be
available? 

Also, could someone confirm my suspicion that the 8-bit limitation on
Raster maps means 8-bits red, 8-bits green and 8-bits blue, not a total
of 8-bits split between RBG.  (Sorry, I'm somewhat lacking in my
knowledge of graphics :-)


Thank you very much for any feedback.

Thanks, 
	Doug Bryant

greetings,

i have been working on a new mapserver (version 3.2) site that was,
until recently, housed with another mapserver site. however, when i
moved my site, several things stopped working.

1. zooms stopped
2. point shape files stopped displaying piont symbols. the legend still
lists the theme howerv, with no symbol as well
3. the scalebar stopped displaying.
4. the temporary gif images (eg. EX4leg98087160517300.gif) that mapserv
displays are now ending up in the public_html directory where the web
pages are.

many other features of mapserver do work however.

to remedy this, i tried to change the mapserv.ini file.
for example:

# Where are fonts and symbols files located
#SYMBOL_PATH=/export/stlime/mapserv/ms_symbols
#SYMBOL_PATH=/home/mdh20t/ms_3.2/ms_symbols
SYMBOL_PATH=/export/usr/local/apache/htdocs/mapserv/ms_symbols

this does not seem to remedy the situation. does anyone have any advice?



the front page is: http://humboldtbay.cnrs.humboldt.edu
click on "online GIS" in the upper left. to check out point shape files,
go to the "Water Quality Data Sets" and select "all events", for
example, and click the button "apply here". you will notice that no
points appear, and the theme "all events" does show up in the legend.

i have attached the mapserv.ini file, my mapserver.html (template) and
mapserver.map files.


thanks, jay, jrp2 at axe.humboldt.edu

With the MapServer CGI interface no, with MapScript, probably yes depending
on the database. If you can get to the database from your favorite scripting
language you can map that data.

You can do some SDE-based mapping now. It's not yet possible to query SDE
data although that work is underway and will be included in the up comming 
release. That release is 4-6 weeks out.

8-bits means there is only support for 256 color/greyscale images. The limitation
is there because the GD library can only output 256 color images.

Subject: installing perl mapscript
Message-ID: <13858AA1A74F30419F319ACB66A9D1220255B0@mercator.topozone.com>

We are installing mapserver onto a winNT machine from the source code
and was successful as long as we limited the install options (no
freetype, no projection support, etc.) in the make file.  But then when
we tried to install mapscript for perl it could not find a 'perlvars'
file (it was looking in ../../ which is the mapserver root folder.  The
'perlvars' file seems not to exist at all.  Does anyone have any ideas?
thanks jameson.

Shortly after switching to perl5.6, I noticed that my install of mapscript
was no longer acting like it has TrueType fonts.

So I recompiled -- used ./configure no problem -- then I tried to rebuild
the mapscript Makefile.  I get the errors below.  Any ideas?

Subject: java mapimage communication without page reloads
Message-ID: <F88BBsQwY6YHkidcDjo0000004a@hotmail.com>

Hi,

I have been using the mapimage applet to work with and display shapefile 
data outputted by Mapserver.

My application is such that the page reloads when layers are turned off/on, 
etc., as well as zoomin/out/pan, etc.

Is there anyway to make the applet's output refresh, and not the page 
itself?  I'm sure I can use JavaScript to update values dynamically which 
are now being reloaded by the page reloads.

Can the applet refresh independent of the page?  If yes, do the page's 
values get updated for the CGI variables outputted by Mapserver?

Any advice or suggestions are valued

Thanks

..Tom

Subject: java mapimage communication without page reloads
Message-ID: <sa76e843.081@smtp.dnr.state.mn.us>

If you use the mapplet.java code I sent then there are a couple of public
methods to handle image loading independent of the page. The key is that
the client (i.e. page) needs to manage the coordinates and layer list and
then construct urls for the applet to load. The javascript to do this has been
written for the most part and was announced to the list a month or two ago.
An example application that uses this stuff is at:

  http://maps.dnr.state.mn.us/landview 

Links to the applet and javascript files can be found in the list message
archives (can't remember off the top of my head). (Tom, if you send me the
mods you made to support the coordinate display with mouse overs I'll add
that to the main mapplet code.)

With mode=map requests there is no way to retrieve computed values (i.e.
extent). A planned modification for the next release is to encode those

Hi,

I have been using the mapimage applet to work with and display shapefile 
data outputted by Mapserver.

My application is such that the page reloads when layers are turned off/on, 
etc., as well as zoomin/out/pan, etc.

Is there anyway to make the applet's output refresh, and not the page 
itself?  I'm sure I can use JavaScript to update values dynamically which 
are now being reloaded by the page reloads.

Can the applet refresh independent of the page?  If yes, do the page's 
values get updated for the CGI variables outputted by Mapserver?

Any advice or suggestions are valued

Thanks

..Tom

Subject: installing perl mapscript
Message-ID: <sa76f069.004@smtp.dnr.state.mn.us>

I imagine the NT Makefile doesn't contain the code to create the perlvars file. Here's an
example:

/usr/local/mapserver/src
-DIGNORE_MISSING_DATA -DUSE_EPPL -DUSE_TTF -DUSE_TIFF -DUSE_JPEG -DUSE_GD_1_2
-I. -I/usr/local/mapserver/src/gd-1.2 -I/usr/local/mapserver/src/gdft -I/usr/local/include/freetype
-L. -lmap -L/usr/local/mapserver/src/gd-1.2 -lgd -L/usr/local/mapserver/src/gdft -lgdft -lttf -ltiff -ljpeg -lm

It's basically a dump of some of the compile options. You could modify the few lines above to fit your
install environment or look at the Makefile.in and figure out how to recreate that using DOS commands.
Then give it another shot.  Building with freetype and proj has been done on NT, binaries are available
at the university website.

We are installing mapserver onto a winNT machine from the source code
and was successful as long as we limited the install options (no
freetype, no projection support, etc.) in the make file.  But then when
we tried to install mapscript for perl it could not find a 'perlvars'
file (it was looking in ../../ which is the mapserver root folder.  The
'perlvars' file seems not to exist at all.  Does anyone have any ideas?
thanks jameson.

Message-ID: <01013119042202.00958@grobi>


Ladies and gentlemen,

I am trying to do a query on a map. The result is a segmentation fault in the
mapserver. Please show where to look for errors, maybe in my compiled mapserver.


I got a map file with a valid extent and a single layer:

name mmplz
status on
size 600 600
symbolset "symbols/newsym.sym"
extent <enter valid values here>
units meters
shapepath "data"
imagecolor 255 255 255

layer
 name leger
 type polygon
 status on
 data plz
 classitem "plz5"
 class
  symbol 2
  outlinecolor 0 0 0
  color 255 255 255
  end
end

In php I write:

$map = ms_newMapObj ("raderg.map");
$mylayer = $map -> getLayerByName ("leger");

which works fine. Then:

$qres = $mylayer -> queryUsingRect ($rect);

where $rect is a valid rectangle -- segfault.


MapServer was configured as follows:

./configure --with-apxs=/usr/sbin/apxs --with-tiff=/usr --with-jpeg
--with-eppl --with-ttf --without-gif --with-gd=/opt/GIS --with-proj=/opt/GIS
--with-php=/home/frosch/src/GIS/mapserver/php-4.0.3pl1

php was configured as follows:

./configure --prefix=/usr/lib/apache --without-ttf --disable-debug
--with-mysql --enable-calendar --enable-dbase --without-zlib
--with-regex=system --with-gd=/opt/GIS --with-apxs=/usr/sbin/apxs

Thanks in advance,


Thorsten

I think you need a QUERY with a QUERYITEM in you map file.  I would see
the accompanying information about map files and especially layers in the
mapserver documentation on their web site.

Subject: PHP - query expression
Message-ID: <Pine.OSF.4.30.0102011213280.4978-100000@student.uq.edu.au>

Currently I am trying to facilitate a query by expression and from a reply
from Daniel I have been working on setting the query expression and
following that with a queryUsingRect() with the coordinates the size of
the map.  However I wish to do this dynamically so my question is, is
there any way to set the query expression of a layer with PHP mapscript?

Any help would be greatly apreciated.

There is a queryObj class with a setExpression() method that you should
be able to use.  However, I just realized that there is no way to access
existing query objects inside a layer from MapScript... you can only
create new ones.  This seems to be true with the Perl MapScript too, is
that possible, Steve?

Hummm... I guess this part of the code hasn't been used much before...
What you could do until this is resolved is not include a QUERY object
in your layer in the .map file, and instead create one in your script
using $query=ms_newQueryObj($layer); ... and then you should be able to
use setExpression() on the new object.

I don't fully understand how this is going to work.  How do I extract the
results from the newly created query?
