r.surf.gauss(1grass) GRASS GIS 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 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
