NAME
r.li.mps - Calculates mean patch size index on a raster map, using a 4 neighbour algorithmKEYWORDS
raster, landscape structure analysis, patch indexSYNOPSIS
r.li.mpsr.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.
