Hi,
I have a mapset with 44 raster maps. I want to check that they do NOT
have overlapping data areas. My thought is to do something like:
r.mapcalc "checkmap=isnull(map1) + isnull(map2) + ... + isnull(map44)"
If the min value of the resulting checkmap is 43, then I know that the
maps are non-overlapping.
Is there a smarter way of doing the test ?
Thanks in advance, Hermann
