29       map=name
30           Name of input raster map
31
32       conf=string

DESCRIPTION

39       r.li.dominance calculates the "dominance's diversity index" as:
40       with:
41
42                     m: number of different patch type
43
44
45                     i: patch type
46
47                     pi: proportion of the landscape occupied by patch type i
48

EXAMPLES

50       To  calculate  dominance's diversity index on map my_map, using my_conf
51       configuration file and saving results in my_out file run:
52
53       r.li.dominance map=my_map conf=my_conf output=my_out
54
55

NOTES

57       Do not use absolute path names for output files.  They  are  raster  if
58       moving   window   disposition  was  selected,  otherwise  they  are  in
59       ~/.r.li/output folder.
60       If input raster is full of null values r.li.dominance returns -1.
61       If you want to have null values instead run
62
63       r.null setnull=-1 map=my_map
64        after index calculation.
