[mapserver-users] Re: Mapserver Projection Errors

[SixDegrees]

The files we're displaying don't have explicit epsg-style codes in them. We
are extracting the projection information using GDAL, which allows us to
convert the projection to Proj.4 before inserting it into the mapfile. The
actual projection information is stored as a WKT. As far as I know, there
isn't a way to convert either of these to an epsg code automatically, since
WKT and Proj.4 are inherently open-ended and may express projections that
simply aren't defined in common epsg. I suppose we could insert our own epsg
definitions into the database, but the dynamic nature of the application
makes this less than ideal.
