I am having problems with Range Doppler Terrain Correction. I use an external DTM, which is available in EPSG 4326. Is that correct? Can I use this or in which coordinate system does it have to be? Later I want to combine the grid with data in EPSG code 25833 in ArcMap. Which coordinate system do I have to set for Map projection in snap? When I set EPSG Code 4326, I get an error message. Which configuration would be correct here?
Thanks in advance!
