[mapserver-users] OFFSITE more values
Hi, I have a rasterlayer with more than 1000 .ecw airial photos and want to set more than one RGB-value transparent with OFFSITE. This works fine: OFFSITE 0 0 0 but I need something like this: OFFSITE [0 0 0,1 1 1,1 2 1] Is there a possibility to solve my problem?

[mapserver-users] Is Shape is nothing but the_geom in PostGIS
Dear All, I am not able to understand is ShapeObj is equal the_geom in the postgis. exp : Select the_geom form table.is equal to select shapeObj from table I need seed shape object instead of the_geom... is that possible ? or I should go with some other processAnyone can guide me .. Please let me know.I am waiting for your great response.

Re: [mapserver-users] Error in msPostGISLayerResultsGetShape(): Got request larger than result set
Presumably this is related to the change in the way query results are handled in MapServer 5.6.5 and the Cartoweb code would need to be updated to use $layer-resultsGetShape() instead of $layer-getShape() to read query results. Another option would be for you to go back to MapServer 5.4.x Daniel Stefan Neumeier wrote: Dear all, I am quite new to mapserver and maybe I am just missing some important configuration step but I hope somebody of you can help me with following problem: When trying to perform a query via a cartoweb-client to a layer stored in Postgis I encounter following error message (It is only the query that is not working the layer itself renders perfect out of the database): MapServer error: Error in msDrawMap(): Failed to draw layer named 'bound'.

Sven, There is no support for multiple offsite values in MapServer. If you have ecw file with lossy nodata areas the usual approach is to convert the files to uncompressed format (ie. GeoTIFF), and then use the GDAL nearblack utility to convert pixels that are nearly black to black so there is a single nodata/offset value. Some folks have also had success deriving a nodata/data mask from this, and using it to develop an alpha (transparency) band which can then be used with the original ecw file via use of a GDAL VRT file grouping the extra band with the original data. This technique is fairly complicated and can have some performance impact on MapServer but it does allow using the original ECW files with exactly masked areas.

This fella describes a hack he made to MapServer's source, to give him a fuzzy matching for the OFFSITE value: http://sites.google.com/site/bpederse/caliwms It may help you out.

[mapserver-users] ODBC connections 32 vs 64 bit

I have a 64 bit windows 7 machine There are two locations to create ODBC connections: This article says a bit http://support.microsoft.com/kb/942976 32 bit \Windows\SysWoW64\odbcad32.exe 64 bit \Windows\System32\odbcad32.exe Does it matter if the ODBC connection is done on 32 or 64 bit? Is there a difference? When I try and create an ODBC connection on 64 bit there are no drivers displayed? Very confusing Thoughts?

[mapserver-users] RE: ODBC connections 32 vs 64 bit
If I recall correctly a 32-bit application can only see 32-bit ODBC sources, so you must use the 32-bit ODBC utility (C:\Windows\SysWOW64\odbcad32.exe) to define the source. I have this scenario on my 64-bit Vista workstation. From Access 2007 I can only see the 32-bit version of my Oracle ODBC source, not the 64-bit version of the source. Access 2007 is a 32-bit application. Hope that helps, Johan.

[mapserver-users] Mapscript c# problem with multiple instances
Hi, mapscript_csharp - 32 bit version 1.0.3679.25032 dated 10/1/2010 All supporting DLLs from Tamas' nightly build site (was last stable version when I grabbed it in January) .NET 3.5 Actually using this in desktop winform app. All has been working fine, until I just tried to move the map rendering into a background thread to stop locking up the UI. No matter what I try - this seems to cause my app to crash out of the background thread (with no error) Crash always occurs at the point where I first try and do something with the OSGeo.MapServer.mapObj Initially it was when I tried to draw the map (having passed in a map object) So I then tried reading the map file again from the disk (so nothing was passed in) - in this case it fails when trying to create the map object from the map file. I tried extracting the code to a separate DLL (with only text strings passed in and out) - this still failed I then tried to run it as a separate AppDomain - which also failed. The only way I have it working to to actually call a separate exe using a temp .map file with my map state and having the exe write the image file back to disk for my main app to pick up. This does work - but seems rather a hack. Am I doing something wrong here / misunderstanding something ? It seems almost as if I can only have one map object per application - or they are trampling on each other in some way I don't understand. Any ideas ?

Re: [mapserver-users] Mapscript c# problem with multiple instances
James, While it's not safe to use the same mapscript object by multiple threads simultaneously, it should work when those threads operate on separate mapObj instances. This would pretty much similar to an ASP.NET application utilizing the mapscript library which I've already used many times this way. By all means it would be helpful if you could provide a sample project for this in order to reproduce this behaviour. Have you already tested with the recent versions of the packages available from http://vbkto.dyndns.org/sdk/ ?

[mapserver-users] multiple labels? also, symbols forced to display within a polygon?
Are there definitive statements somewhere in the mapserver/mapscript documentation on whether/how multiple labels, with their own string content, color, font, placement, etc., can ALL be simultaneously displayed on each placed feature within a layer? I've seen some hints that this can be done, but the infrastructure does not seem to support it. I'm doing some rather 'brittle' things with php-mapscript ShapeObj, and it appears my attempts to do multiple things with Labels and Classes results in the last such action effectively overwriting previous actions on the same ShapeObj. So I want between zero and four labels to appear per feature, but only one does. Really, I'm just trying to display multiple symbols, between zero and five per polygon feature, depending on client app params, and that basically works, BUT it does not appear that symbol placement exploits the scheme used in label placement where the polygon centroid is rejected as placement point if said centroid is not within polygon. Any suggestions or doc refs appreciated, Thanks, Robert H ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
