[mapserver-users] OGR problems

[Derek Bain]

Hi

My problem with DNC's were traced to the use of the extents. I use a top level map file with the extents set to the whole world and INCLUDE other map files which define the extents for each layer. This worked okay until I used DNC's. I created a seperate map file for DNC's and had to set the extents at the top of the map file to be the same as the extents for the layers.

Now I can draw the layers onto the test.png file. HOWEVER, this only works with the shp2map file supplied by FWTools (v2.2.0) When I try to get the map from MapServer using my client, this is what appears in the ms_debug.txt file from MapServer

The OGR connection is okay because shp2img opens it.

I see that MapServer is at 5.2 but there is no Windows Binary available for this build. 

Can someone inform me if v5.2 uses the latest gdal/ogr source code. Also, can I copy files from FWTools to Mapserver to get this working and if so, which file(s)
I don't want to break Mapserver.
