r.surf.random(1)	    GRASS GIS User's Manual	      r.surf.random(1)

NAME
       r.surf.random   - Produces a raster surface map of uniform random devi-
       ates with defined range.

KEYWORDS
       raster, surface,	random

SYNOPSIS
       r.surf.random
       r.surf.random --help
       r.surf.random   [-i]   output=name     [min=integer]	 [max=integer]
       [--overwrite]  [--help]	[--verbose]  [--quiet]	[--ui]

   Flags:
       -i
	   Create an integer raster map

       --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=nameA [required]
	   Name	for output raster map

       min=integer
	   Minimum random value
	   Default: 0

       max=integer
	   Maximum random value
	   Default: 100

DESCRIPTION
       r.surf.random  produces	a  raster map layer of uniform random deviates
       whose range can be expressed by the user. It is essentially the same as
       r.surf.gauss,  but  uses	 a linear random number	generator instead.  It
       uses the	random number generator	drand48() or rand(), depending on  the
       user's platform.

       Histogram of map	generated with r.surf.random

EXAMPLE
       g.region	-p n=228500 s=215000 w=630000 e=645000 res=10
       r.surf.random out=random	min=0 max=100
       # check result
       r.univar	random

SEE ALSO
	  r.random.surface,   r.surf.contour,	r.surf.fractal,	 r.surf.gauss,
       r.surf.idw, v.surf.rst
