Excellent Maciek and Glynn :) Although the logic is different (in the solution of Maciek I do a check before the NULL value, while in the solution of Glynn I do a check before non-NULL values), I believe that the result is the same. One note: with the solution of Glynn (at least using the shell from QGIS) it works with single quotes ' and not with double quote " . gab@gab-laptop:~$ r.mapcalc "output_2 = if(!isnull(a),a,if(!isnull(b),b,c))" bash: !isnull: event not found gab@gab-laptop:~$ r.mapcalc 'output_2 = if(!isnull(a),a,if(!isnull(b),b,c))' # OK
