I need some help with mapcalc.
I have two rasters:
A contains cells with 1 or 2 or null;
B has values>=1 or null.
I would like to delete areas where A overlaps with B, then get a resulting map where there is 1 where B has a value>=1 and null where both A and B have >= 1.
It seems easy but I'm trying many different combinations unsuccessfully.
