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.<br><br>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<br><br>Fri Jul 25 10:36:14 2008].812000 msOGRFileOpen(): OGR error.
