Hi,
a thought I've had for a while- should we have some r.compare script to
test if two raster maps are the same. Currently I use r.univar and check
sum= and others match, which is slightly unsatisfactory, as is r.mapcalc
diff=map1-map2 + 'r.univar map=diff'. My idea is cell data equality, not
metadata (timestamps etc).
a flag could have it output a checksum/md5sum too.
Should it base the exit code on the yes/no answer?
I guess a v.compare could simply run `diff` on the two folders in
$MAPSET/vector/ (with g.findfile adjusting for @otherMapset as needed)
thoughts?
