r.surf.gauss(1grass) Grass User's Manual r.surf.gauss(1grass)

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] [--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

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 essentialy 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
