Hello,
I'm working with Mars raster data; my basemaps are HiRISE and CTX raster images projected to Mars_Equirectangular (the standard used for Martian geomatics). I have a raster image imported from ENVI that already has all of its georeferencing included, so when it gets added to my map it projects on the fly. Problem is, it's a few (10s-100s) meters off from where it should be based on the HiRISE images below it. How can I transform or re-georeference it to the lower image?
