How to know which projection is suitable? For Germany there are several systems(I just searched Germany on the website):
SR-ORG:7325: ETRS89 Zone32 Germany
SR-ORG:7411: LAMBERT WGS84, GERMANY
SR-ORG:7519: DHDN / 3-degree Gauss-Kruger zone 6
SR-ORG:7520: DHDN / 3-degree Gauss-Kruger zone 6
SR-ORG:8614: Eastern Germany
SR-ORG:8615: Eastern Germany
how to use the text that is generated in ESRI WKT definition, just put it in the panel?
