NAMEr.surf.random - Produces a raster surface map of uniform random deviates with defined range.KEYWORDSraster, surface, randomSYNOPSISr.surf.randomr.surf.random --help r.surf.random [-i] output=name [min=integer] [max=integer] [--overwrite] [--help] [--verbose] [--quiet] [--ui] Flags:
Parameters:
DESCRIPTIONr.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.EXAMPLEg.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 Figure: Random surface example (min: 10; max: 100) With the histogram tool the cell values versus count can be shown.
