NAME

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

KEYWORDS

       raster, surface, random

SYNOPSIS

       r.surf.gauss
       r.surf.gauss --help
       r.surf.gauss   output=name    [mean=float]    [sigma=float]    [seed=integer]    [--overwrite]   [--help]
       [--verbose]  [--quiet]  [--ui]

   Flags:
       --overwrite
           Allow output files to overwrite existing files

       --help
           Print usage summary

       --verbose
           Verbose module output

       --quiet
           Quiet module output

       --ui
           Force launching GUI dialog

   Parameters:
       output=name [required]
           Name for output raster map

       mean=float
           Distribution mean
           Default: 0.0

       sigma=float
           Standard deviation
           Default: 1.0

       seed=integer
           Seed for random number generator
           The same seed can be used to obtain same results or random seed can be generated by other means.

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.
