vector, statisticsSYNOPSIS
v.randomv.random help
v.random [-zd] output=name n=integer [zmin=float] [zmax=float] [--overwrite] [--verbose] [--quiet]
Flags:
- -z
Create 3D output- -d
Use drand48() function (default=rand() )- --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.SEE ALSO
UNIX man pages for rand(3) and drand48(3).g.region, r.random, v.perturb, v.sample
BUGS
The RNG used by v.perturb should probably be added to this program.Currently no attribute table is generated. Please send any bug fixes and comments to the grass development team.
