r.surf.gauss(1grass)

r.surf.gauss1grass

Generates a raster map using gaussian random number generator. mean and standard deviation of gaussian deviates can be expressed by the user.

Usage

r.surf.gauss

r.surf.gauss --help

Keywords

Overview

r.surf.gauss produces a raster map of Gaussian deviates whose mean and standard deviation can be expressed by the user. It uses a Gaussian random number generator. It is essentially the same as r.surf.random, but uses a Gaussian random number generator instead.

Examples

g.region -p n=228500 s=215000 w=630000 e=645000 res=10
r.surf.gauss out=gauss mean=0 sigma=10
# check result
r.univar gauss

With the histogram tool the cell values versus count can be shown.
