DESCRIPTION

39       r.li.patchnum is a patch index for r.li program.
40       It calculates the function
41        f(sample_area)= Patch_Number
42       This index is calculated using a 4 neighbour algorithm
43

EXAMPLES

45       To calculate patch number index on map my_map, using my_conf configura‐
46       tion file and saving results in my_out file run:
47       r.li.patchnumber map=my_map conf=my_conf out=my_out

NOTES

51       An that is full of null values is considered to have zero patch.
52       If you want to have null values instead run
53
54       r.null setnull=0 map=my_map
55        after index calculation.
