NAME
v.random - Randomly generate a 2D/3D vector points map.
KEYWORDS
vector, statistics
SYNOPSIS
v.random
v.random help
v.random [-zdb] output=name n=integer [zmin=float] [zmax=float] [--overwrite] [--verbose] [--quiet]
Flags:
- -z
- Create 3D output
- -d
- Use drand48() function instead of rand()
- -b
- Do not build topology
- --overwrite
- Allow output files to overwrite existing files
- --verbose
- Verbose module output
- --quiet
- Quiet module output
Parameters:
- output=name
- Name for output vector map
- n=integer
- Number of points to be created
- zmin=float
- Minimum z height (needs -z flag)
- Default: 0.0
- zmax=float
- Maximum z height (needs -z flag)
- Default: 0.0
DESCRIPTION
v.random randomly generates vector points within the
current region using the selected random number generator.

v.perturb
should probably be added to this program.
