[mapserver-users] Custom Projections with WMS Server

Hi,

Sure, just edit the "epsg" projection file.  Support for Google
projection 900913 is added just this way by inserting a new line as

# Google-projection
<900913> +proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0
+x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgrids=@null +no_defs <>

Then this new projection can be used in the mapfile and it will be
advertised in GetCapabilities. However, some clients may not like
unknown projections because they can't do reprojection on-the-fly then.
Some clients like OpenJUMP just do not care and they take the bbox from
a map window and what ever SRS the user has selected to use.

So Mapserver will work but it is not guaranteed how the clients behave.
