NAME

6       r.surf.gauss   -  Generates  a  raster map using gaussian random number
7       generator.
8       Mean and standard deviation of gaussian deviates can  be  expressed  by
9       the user.

DESCRIPTION

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

EXAMPLE

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

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