- Create an integer raster map
- --overwrite
- Allow output files to overwrite existing files
- --verbose
- Verbose module output
- --quiet
- Quiet module output
Parameters:
- output=name
- Name for output raster map

- 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 essentialy 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.
