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

Tue Sep 18 08:26:05 PDT 2012

Success, the entry was:

+proj=utm +zone=32 +ellps=GRS80 +units=m +no_defs

adding +datum=WGS84 in proj4-file and proj4text-columnentry in the mapbender- and alkis-databases solves the problem.

thank you..;o))
