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:

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.
