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.
