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 input=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:
- input=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:
![](rlimps_formula.png)
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 input=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.
