[mapserver-users] WFS intersect request

[Alexandre Dube]

Hello,

   If you run a WFS GetCapabilities request on your server, it should 
tell which filters it supports, see :
http://mapserver.org/ogc/filter_encoding.html#server-side

   Someone correct me if I'm wrong, but I think MapServer needs to be 
compiled with GEOS in order to do intersect filters.

HTH,

Alexandre
