I have two raster datasets of Antarctica, however, they do not match spatially as one of the raster should be rotates 90 degrees. Is there a way to do this in QGIS?

If the rasters have correct location but one of them is rotated, then you can georeference incorrect raster based on the correct (georeferenced) one. You can either use Raster -> Georeferencer tool to do the job, or use Freehand raster georeferencer plugin which has the function to rotate the raster data.

You can download Freehand raster georeferencer plugin from the plugin manager.

  • I tried this, but this tools gives an error: "CRS does not match: Found existing georeferencing in raster but its CRS does not match the CRS of the map. Unable to reproject." I checked in the layer properties and the CRS is defined as Antarctic Polar Stereographic (EPSG: 3031) Commented Aug 3, 2019 at 14:09
