I'm trying to open a Gaus Krueger shapefile, which comes without any .prj files, in QGIS. These files are not really up to date but they're the only data i can get. So the first question is: Is it possible to project them on any world map in the right position by using the "OpenLayersPlugin"? And: The other part of the data is more updatet so its CRS is ETRS 89 / UTM 32N. Is there a way to project both on the same map for the same time?
When I insert the GaussKrueger data into QGis, it says that die CRS of the GaussKrueger data is undefined and preset to EPSG 4326. What does that mean?
So I need a way to show both, old and new data, beside each other on the right position in the map (Google Satellite from OpenLayersPlugin), explained for dummies^^
