Thanks for your answer, Ed, the problem is that i don't know how to write an url with negative values in the extent. No one of these works :
http://localhost/cgi-bin/mapserver.exe?mode=map&map=my_path_to_mapfile.map&mapext=-10+50-20+60 http://localhost/cgi-bin/mapserver.exe?mode=map&map=my_path_to_mapfile.map&mapext=+-10+50+-20+60 http://localhost/cgi-bin/mapserver.exe?mode=map&map=my_path_to_mapfile.map&mapext=-10%2050-20%2060 http://localhost/cgi-bin/mapserver.exe?mode=map&map=my_path_to_mapfile.map&mapext=%20-10%20+50%20-20%20+60 Sorry if it's a trivial problem :-/, i'm always getting this result : loadForm(): Web application error. Not enough arguments for mapext. Thanks for your help ! Laurent -- Laurent Jégou IGE Cartographe UTM - Dépt.
