I'm trying to delete a map that I used as a mask before, but I cannot delete it using g.remove. It displays this:
there is another map that uses that one as base map, it maybe a RGB composition or something like it. If you don't find what it is, just delete the map from the grassdata directory, you will find it in
cellhd folders in
[g.remove] with flag
-b can be used to remove base maps.
