r.li.dominance: Calculates dominance's diversity index on a raster map

NAME

r.li.dominance - Calculates dominance's diversity index on a raster map

KEYWORDS

raster, landscape structure analysis, diversity index

SYNOPSIS

r.li.dominance r.li.dominance help r.li.dominance 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.dominance calculates the "dominance's diversity index" as: with: m: number of different patch type i: patch type pi: proportion of the landscape occupied by patch type i
EXAMPLES
To calculate dominance's diversity index on map my_map, using my_conf configuration file and saving results in my_out file run: r.li.dominance 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.dominance returns -1. If you want to have null values instead run r.null setnull=-1 map=my_map after index calculation.
