[Mapserver-users] Extent & Projection for Germany

[uli]

Gauss-Krueger needs lat_0=0 and lon_0=9 . Your false easting (x_0) is
3500000, not 500000. Your map units have to be meters.

But it is still easier:

- since your shape has the same projection as the whole map, you may simply
delete all projection definitions

- or - if you installed PROJ with the EPSG codes - specify your projection
like:
PROJECTION
  "init=epsg:31493"

I'am shure the problem is the Projection or the EXTENT or both. Does
anyone know how to fill in these parts correctly?
