[Mapserver-users] Geotiff and Extent confusion

[Dylan Keon]

 From your mapserv -v I see you have both GDAL and MapServer's TIFF 
support enabled.  If you compile --with-gdal it's also a good idea to 
compile --without-tiff.

Also, is your EXTENT correct?  It should be in the form of 'minx miny 
maxx maxy'.  I think you might have the miny and maxy switched.
