31
32       conf=string

DESCRIPTION

39       r.li.mps  (mean  patch size) calculates the mean size of the patches in
40       the sampling area as:
41       with:
42
43                     A:sampling area size without null cells
44
45                     Npatch: number of patches
46

EXAMPLES

48       To calculate mean path size index on map my_map, using my_conf configu‐
49       ration file and saving results in my_out file run:
50
51       r.li.mps map=my_map conf=my_conf output=my_out
52
53

NOTES

55       Do  not  use  absolute  path names for output files. They are raster if
56       moving  window  disposition  was  selected,  otherwise  they   are   in
57       ~/.r.li/output folder.
58       If input raster is full of null values r.li.mps returns 0.
59       If you want to have null values instead run
60
61       r.null setnull=0 map=my_map
62        after index calculation.
