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
