Hi Mapbenders,

I'm trying to project a wms with the change epsg button. The function
works, but the resulting coordinates are not correct. They differ about
32m to west and about 175m to the south to a "real" dhdn-shape. I tried
two proj4-parameters in the spatial_ref_sys table for epsg 31467:

+proj=tmerc +lat_0=0 +lon_0=9 +k=1.000000 +x_0=3500000 +y_0=0
+ellps=bessel +datum=potsdam +units=m +no_defs
+proj=tmerc +lat_0=0 +lon_0=9 +k=1.000000 +x_0=3500000 +y_0=0
+ellps=bessel +datum=potsdam +nadgrids=BeTA2007 +units=m +no_defs  

but nothing changes.

Thanks for any help!

Best regards
