NAME

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

KEYWORDS

raster, landscape structure analysis, dominance index

SYNOPSIS

r.li.richness
r.li.richness help
r.li.richness 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.richness calculates the "richness's diversity index" as:
with:
m: number of different patch type

  

EXAMPLES

To calculate richness's diversity index on map my_map, using my_conf configuration file and saving results in my_out file run:

r.li.richness 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.richness returns -1.
If you want to have null values instead run
after index calculation.
