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.Histogram of map generated with r.surf.gauss (mean=0, sigma=10)
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
