NAME
v.random - Randomly generate a 2D/3D GRASS vector points map.
KEYWORDS
vector, statistics
SYNOPSIS
v.random
v.random help
v.random [-zd] output=string n=integer [zmin=float] [zmax=float] [--overwrite]
Flags:
- -z
- Create 3D output
- -d
- Use drand48() function (default=rand() )
- --overwrite
- Force overwrite of output files
Parameters:
- output=string
- vector file to be created
- 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
