r.mcda.ahp

Generates a raster map classified with analytic hierarchy process (AHP).

Command linePython (grass.script)

r.mcda.ahp [-k] criteria=name [,name,...] pairwise=string output=string [--verbose] [--quiet] [--qq] [--ui]

Example:

r.mcda.ahp criteria=name pairwise=string output=string

grass.script.run_command("r.mcda.ahp", criteria, pairwise, output, flags=None, verbose=False, quiet=False, superquiet=False)

Example:

gs.run_command("r.mcda.ahp", criteria="name", pairwise="string", output="string")

DESCRIPTION

The r.mcda.ahp Generate a raster map classified with analytic hierarchy process (AHP) [Saaty, 1977 and Saaty & Vargas, 1991]

NOTES

It is mandatory to build a pairwise comparation table with the same order of input of criteria maps in the criteria field.

Example: r.mcda.ahp criteria=reclass_slope,reclass_sand,reclass_elev pairwise=pairwise output=outputMap

The file "pairwise" has to have a structure like this:

#start file

1.0, 0.2, 3.0

5.0, 1.0, 5.0

0.3, 0.2, 1.0

#comment: order: reclass_slope,reclass_sand,reclass_

#end file

The first row and first column are related to the first criteria (reclass_slope in our case); the second row and second column are related to the second criteria (reclass_sand in our case) and the third row and third column are related to the third criteria ( reclass_elev in our cas), and so on.

In the work directory should be generated a log.txt file were you can find additional information like: eigenvectors, eigenvalues, weights
