I have read all sorts of entries about CRS inconsistencies of different layers but it just didnt help to solve my problem.
So far I have always used ArcGIS and recently changed to QGIS. My data consists of a DEM (find attached: 'rangsdorf.ovr') and several sounding points (find one example attached: 'Layer1_Verlust_mit_Maechtigkeit.shp'). All those layers have the same coordinate system (UTM) and looking at the data in ArcGIS everything is visualised the way I want it to be - the points are located within the DEM.
However, loading it into QGIS, the raster is located somewhere completly different - I really dont get it. As I said, it should all have the same coordinate reference system, and anyway I am using OTF so I´m absolutly clueless.
