A and B do not overlap, and I should take the values of A and B also
(always). Then.....in areas that are empty, I would then put the values of
C.
I tried with r.mapcalc "output = if((isnull(a)),b,if(isnull(b),a),c)"
but I lose the values of C
This should work:
r.mapcalc 'd=if(isnull(a),if(isnull(b),c,b),a)'
If map a is null check if b is null too. If so, use c; if not - use b.
Otherwise use a.
Or:
r.mapcalc 'd=if(isnull(a|||b),c,if(isnull(a),b,a))'
If both a and b are null, use c; if a is null use b, otherwise use a.
