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

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