DESCRIPTION

r.pi.nlm.circ is a random patch generator. It creates a random landscape with defined attributes.

NOTES

The user must specify the names of the raster map layers to be used for input and output, the landcover, the size, the count used, the keyval of the class of interest of the input raster map.
Input
The Input is potentially used for Landcover, size and count.
keyval
The keyval is used to compute landcover and count if not declared.
landcover
The landcover defines the amount of cover, if not declared, the landcover of keyval of input is used.
count
The count defines the amount of patches in the landscape, if not defined, the amount of patches in the input is used, if 0 is inserted, random amount of patches are created. Values from 1-n can be defined for a fixed number of patches.
size
The size defines the size of the artificial landscape. If not declared the size of the actual region is taken.
seed
The seed defiens the seed of random points. If all settings and the seed is fixed, then the patches won't be random anymore, but fixed. The user will receive everytime the same landscape.
xxx
The xxx ....
xxx
The xxx ....

EXAMPLE

An example for the North Carolina sample dataset:
