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

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.
