Hello,
we encountered a mysterium here. We have one zip folder which contains a raster file (dem). If we unpack this folder on one laptop, the dem has the right coordinate system (which is ETRS...). If we unzip the same folder on another laptop it hast a wrong coordinate system (WGS...(Northern Hemisphere)).
I have no clue why, maybe someone has an idea?
Greetings,
Daniel
Perhaps when you're checking the CRS of the data you have a different CRS set up in the data frame of ArcMap - assuming you're checking the data CRS using ArcGIS Desktop?
