DESCRIPTION

Creates a random generated map with values 0 or 1" "by given landcover and agglomeration value.

NOTES

Related to r.pi.nlm.circ but using fractal landscapes instead of circular growth. Per default the size of the whole region is used for generating a random landscape, this can be constraint by assigning a class in a raster map with acts as mask for the generation of the random landscape (nullval). The landcover can be set manually, randomly or be taken from the input class coverage. The agglomeration level (sharpness) can be set manually or randomly. If similar random landscape with differing e.g. percentage coverage should be generated, then the seed can be set using any number and reused for any subsequent analysis.

EXAMPLE

An example for the North Carolina sample dataset: A random landscape with random percentage coverage and agglomeration factor:
r.pi.nlm output=nlm.1 landcover=50
A random landscape is generated using the percentage coverage of class 5. The agglomeration factor is set randomly:
r.pi.nlm input=landclass96 output=nlm.2 keyval=5
