r.li.patchnum help
r.li.patchnum map=name conf=string output=name [--overwrite] [--verbose] [--quiet]

--overwrite

Allow output files to overwrite existing files

conf=string

Configuration file

output=name

Name for output raster map

DESCRIPTION

r.li.patchnum is a patch index for r.li program.
It calculates the function
f(sample_area)= Patch_Number
This index is calculated using a 4 neighbour algorithm

EXAMPLES

To calculate patch number index on map my_map, using my_conf configuration file and saving results in my_out file run:
r.li.patchnumber map=my_map conf=my_conf out=my_out

NOTES

An that is full of null values is considered to have zero patch.
If you want to have null values instead run

r.null setnull=0 map=my_map
