Re: [mapserver-users] Mapserv problems on Fedora
Hi Frank,
Adding more to to the malloc fixed the crash, but the regex is failing
:( and should be ok:
Breakpoint 1, msEvalRegex (e=0x4e9873 "\\.map$",
s=0x7232a0 "/u/data/maps/google-agg.map") at mapfile.c:79
...
89if(ms_regexec(&re, s, 0, NULL, 0) != 0) { /* no match */
(gdb) p ms_regexec(&re, s, 0, 0, 0)
$1 = 1
(gdb) c
Continuing.
Content-type: text/html
MapServer Message
msEvalRegex(): Regular expression error. String
(/u/data/maps/google-agg.map) failed expression test.
Program exited normally.
This should NOT be happening. Arrrgh!
Anyone else using fc8 on a x86_84 box?

Steve,
Ugly! I don't know why it would be needed, but you could try changing this:
regex_t* sys_regex = (regex_t*) malloc(sizeof(regex_t));
to:
regex_t* sys_regex = (regex_t*) malloc(sizeof(regex_t)+1000);
in mapregex.c.
I suspect there is a mixup between the regex include files being
used and the library being used or possibly structures aren't being
sized properly due to some sort of type size issue.
Interestingly in my mapfile.c from the 5.0 branch line 84 of
mapfile.c is:
if(ms_regcomp(&re, e, MS_REG_EXTENDED|MS_REG_NOSUB) != 0) {
rather than calling regncomp() directly. Perhaps there has been
a fix since 5.0.2?

RE: [mapserver-users] Mapserver + Openlayers legend problem
An embedded scale bar is just not going to work with an OpenLayers type of interface. (unless, I guess, you use the single, non-tiled layer type in OpenLayers. But then you aren't going to get the cool Googley Goodness slippy map effect. http://www.openlayers.org/dev/examples/mapserver_untiled.html ) The problem is that OpenLayers splits your map window request up in to little tiles. This allows it to easily add more tiles outside of your map window, giving that seamless appearance. When OpenLayers requests all of the tiles for your map, each tile is an individual call to MapServer and your MapServer doesn't know that all of these request are related, they are just requests. So, if you have an embeded scalebar or legend, it will show up in each tile. If you are using OpenLayers, there might be a way to place a legend graphic on top of your map, kind of like the overview map. http://www.openlayers.org/dev/examples/overviewmap.html Otherwise, you may just want to have a spot outside of the map div where you show a legend.

[MAPSERVER-USERS] How to reference multiple byte characters in symbol file?
My understanding is that the only type of vector (non-bitmap) font I can use
for mapserver is a TrueType font.
I'm starting with a PostScript Type 1 font. (And a quick test seemed to
confirm that this is not directly useable.) I used fontforge
(http://fontforge.sourceforge.net/) to generate a TrueType font from the
PostScript font. The problem here is that the characters I want are now
located way above the single byte range (e.g. way above character number 255
within the font.)
Is there any way to reference a multibyte character in the CHARACTER
declaration of the symbol file:
http://mapserver.gis.umn.edu/docs/reference/symbology/syntax
Something akin to the \x{ab}\x{cd} (or \x{abcd} ?) notation of Perl? This
exact notation doesn't work for me, it just interprets the characters as
those
individual ASCII characters (i.e. backslash, lower case x, open curly brace,
etc.) I am able to enter non-ASCII characters into the symbol file (I use
hexl-mode in emacs), but mapserver seems to interpret these as individual
byte
characters, regardless of what encoding I intend. I have multi-byte
characters (UTF-8) in my data and deal with that with the ENCODING
declaration
within LABEL in the map file:
http://mapserver.gis.umn.edu/docs/reference/mapfile/label
But I don't see any such declaration for a symbol file.
This mailing list thread is somewhat related:
http://www.nabble.com/-UMN_MAPSERVER-USERS--Special-characters-in-mapfile-to901771.html#a901771
But it doesn't really help, since those examples are still just for single
byte chars.
This isn't an urgent need. I am able to work around it by editing the
TrueType font file (again with fontforge) and copy the couple of chars that
I
need down to empty spots in the single byte range, and reference those
instances. But I am curious whether or not this is doable without that kind
of hack.

[mapserver-users] Mapserver + Openlayers legend problem
Hi everyone, I'm beggining with mapserver + openlayers. The problem is that I cannot show a legend of my layers, because if I use the 'LEGEND keyword' into the mapfile, the legend is shown on every tile of the openlayers's map. I've found the same problem for the SCALEBAR. The definition of the LEGEND in the mapfile is simple: LEGEND STATUS EMBED POSITION LR TRANSPARENT TRUE END And you can see the problem here: http://www.ietcat.org/htmls04/cat/PDF_PTMB/legend_problem.gif Does anyone know how to solve this repetition problem?

Try building the tileindex like gdaltindex tileindex.shp c:\full\path\to\images\*.jpg (this is Windows syntax).

AW: [mapserver-users] JGW+JPG -> TIFF
Hi, thanks for your answer. I was able to implement one of the pictures into a new layer like you described. Two new problems turn up. 1) The image quality is really bad, the picture gets all reddish and yellowish and seems to loose pixels. I use PNG as format for all my maps. All the other (polygon) look ok this way. I tried PNG24 but I'm loosing transparency there. Is there another recommendable image-format? or what can I do to improve the picture quality in mapserver? 2) I have 80 orthofotos. Since I don't want to add a layer for each one I created a tileindex with gdaltindex.exe ... the created dbf file contains one column called LOCATION and has all the name of my jpegs in it but when I use it in mapserver the screen stays white, no pictures show up.

If you create a layer in the mapfile, with DATA set to your-raster.jpg, it automatically reads .jgw (it must have the same name of the jpg file) and users its informations for georeferencing it. Specify also TYPE raster and if you want MIN/MAXSCALE. If you prefer tiff file, you must convert jpg in tif by means of a graphic editor and then translate .jgw in .tfw. It could request not only renaming the file, but also modify some coefficients defined inside the .jgw file (open it with notepad, it is simple text). Hope this helps.

point I click on the map. I used the following code in the mapscript
layerObj oTempLayer = map.getLayerByName("Circle");
oTempLayer.open();
oTempLayer.status = (int)mapscript.MS_ON;
pointObj point = pixel2point(new pointObj(x, y, 0, 0));
rectObj oRect = oTempLayer.getExtent();
shapeObj oShp= oRect.toPolygon();
pointObj oPoint = oShp.getCentroid();
oPoint.setXY(point.x, point.y, 0);
oShp.draw(map, oTempLayer, oImg);
oImg = map.draw();
oTempLayer.draw(map, oImg);
Can you please help me to rectify the above code?
Thanks,
Sucharita

[mapserver-users] Reg: Mapserver 3D GIS Capabilities
Dear All, I am Veknat,I am developing web application based on C# asp.net.Here I want to use 3D gis analysis(At least i want to show my data in 3D view).Is Mapserver has 3D capabilities?.Let me know.. I am waiting for your great response. Advanced Thanks. Regards, Venkat. ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
RE: [mapserver-users] Mapserver and Microsoft SQL Server 2008
Thanks for the reply, I did notice the geometry_columns table was missing
and at first when I added it, I got SQL errors, but after a few tweaks, I no
longer get the errors when I have a geometry_columns table in my database. I
narrowed the error down to the layer.open() command, and found where the
error occurs in the source code of the sql server plugin dll. For some
reason it cannot locate the geometry column in either the table itself or
the geometry_columns table, even though both are specified as 'the_geom'.
I'm looking into the security now, I did notice that I could not set the
owner of the geometry_columns table... CREATE TABLE geometry_columns OWNER
TO owner, SQL isn't liking the 'OWNER' part... Otherwise I'll have another
look at the webserver permissions, but those have never been a problem...
At a bit of a loss here and running out of ideas...
Thanks
Chris

I'm guessing here, never having used SQL Server
This is like it is with PostGIS because PostGIS is not fully integrated with
Postgres, but a third party addon. In SQL Sever 2008 I would assume you'd
use "alter table add ..." to add a new geometry column, like you do for any
other native datatype.
Assuming MS actually followed someone else's standard for a change, your
database should have a geometry_columns table with the metadata of your
geometry column & its table there. See if that all seems OK first. My guess
is that mapserver will be reading some info about the geometry from there...
So your first check should be that the geometry column exists in both the
table you created & the geometry_columns table.
Other than that, I can only think of a permissions problem somewhere? Is the
web server user running the mapserver cgi able to access the SQL db/table
OK??
Someone who has more SQL Server expertise will have to advise any further
:-)

[mapserver-users] error_output
Good morning, I am a student of geoinformatics in the Czech Republic. I am just finishing my diploma thesis about a map server and I have a problem with my aplication. Sometimes there is an error in my client. The error of client is in displaying received images (they look like those saved in computer). I am sending you four images for illustration : data- this is how I can see an orthophoto map in my aplication data_png- this is the image of orthophoto map how is saved in my computer Can you write me please where the problem is? Or what do you think I should change? Thank you best regards Petra Pietrasova Czech Republic <><>___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
RE: [mapserver-users] Reg: 3D Mapping Capability for Mapserver
Deegree has a Java implementation of the OGC WPVS service, which can generate 3D views from WCS/WMS and WFS. However you don't make analysis, I think (which kind ?)
