Ciao grass users. I have three maps A, B, C.
I would use r.mapcalc to combine them according to this logic: Put the values of A and if A is null you put the values of B and if B is null you put the values of C. I have tried in various ways without success. .. now I'm trying with a double IF... r.mapcalc "output = if((isnull(a)),b,if(isnull(b)),c)" .....but in this case I do not put the values of A Help / advice?
