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.
