I have a question about projections. I have a hillshade raster with UTM 31N projection (I reprojected this from WGS 84). I also have a satellite image that I need to georeference. For georeferencing I choose UTM 31N as projection for the modified satellite image, however when it opens in QGIS, it is not in the same spot as the hillshade raster. When I change the projection of the modified satellite image to WGS 84, it works well and they overlap. What did I do wrong?

UL: 41˚46'40'' / 0˚30'19''
LR: 42˚37'28'' / 1˚01'37''

  • Please edit the question to include the extents of the projected and unprojected rasters.

  • We need the extent of both rasters to be able to provide any assistance. Please be sure to mark ordinates with direction (N/S/E/W/X/Y)

You thought to reproject to UTM by using Set Layer CRS, which is wrong. You have altered the CRS, but not the extent.

You need Raster -> Projections -> Warp to reproject raster data correctly to another filename and CRS.
