[mapserver-users] WFS with several SRS?

[Jeff McKenna]

Hello,

Some quick notes that may assist you as you travel down this path:

- for any WMS/WFS/OGC mapfiles, I always
   - check my GetCapabilities response in a text editor for any 
"Warning" text, if any exist then change the mapfile until all warnings 
from GetCapabilities are gone
   - make sure that each layer has a PROJECTION object (the source 
projection for that layer)
   - make sure to have a MAP-level PROJECTION object
   - make sure the WEB object's METADATA parameter has a "wms_srs" or 
"wfs_srs" or "ows_srs" line that lists/advertises several different 
projections (as previously mentioned in another response)

Hope that helps you through your travels.

-jeff
