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