DESCRIPTION
r3.mapcalculator provides a GUI frontend to r3.mapcalc. Up to 5 maps can be combined using simple expressions. In the expert mode, it runs r3.mapcalc for more complex expressions. Enter an r3.mapcalc expression in the formula field using the format: A+C or exp(A+C)+(B-2)*7 where A, B, C are 3D raster volumes entered in the A field, B field, and C field. Do not enter output file in the formula field: correct: A+B; incorrect: newfile = A+B. Use no spaces or blanks. Expert mode runs r3.mapcalc for more complex expressions.
