## DESCRIPTION

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.

## EXAMPLE

    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

Figure: Random Gaussian surface example (mean: 0; sigma: 10)

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