[Mapbender-users] Projection to DHDN3 GK Zone3 EPSG:31467

Tue Sep 18 07:37:56 PDT 2012

We do it the other way around (31467 to 25832) and it works with the projection settings I send you.
What is the data source of the alkis-data-wms (Shapefile / PostGIS etc.)?

I try to project alkis-data-wms with an initial projection ETRS89/UTM32N epsg:25832 to epsg:31467. As reference test data I use an alk-shape with epsg:31467.
