NAME

r.li.mps - Calculates mean patch size index on a raster map, using a 4 neighbour algorithm

KEYWORDS

raster, landscape structure analysis, patch index

SYNOPSIS

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

Flags:

--overwrite

Allow output files to overwrite existing files
--verbose

Verbose module output
--quiet

Quiet module output

Parameters:

map=name

Name of input raster map
conf=string

Configuration file
output=name

Name for output raster map

DESCRIPTION

r.li.mps (mean patch size) calculates the mean size of the patches in the sampling area as:
with:
A:sampling area size without null cells
Npatch: number of patches

EXAMPLES

To calculate mean path size index on map my_map, using my_conf configuration file and saving results in my_out file run:

r.li.mps map=my_map conf=my_conf output=my_out

NOTES

Do not use absolute path names for output files. They are raster if moving window disposition was selected, otherwise they are in ~/.r.li/output folder.
If input raster is full of null values r.li.mps returns 0.
If you want to have null values instead run

r.null setnull=0 map=my_map
after index calculation.
