## NAME

r.le.pixel - Contains a set of measures for attributes, diversity, texture, juxtaposition, and edge.

## KEYWORDS

raster, landscape structure analysis, patch index

## SYNOPSIS

r.le.pixel
r.le.pixel help
r.le.pixel [-euz] map=string [sam=string] [reg=string] [att=string[,string,...]] [div=string[,string,...]] [te1=string] [te2=string[,string,...]] [jux=string[,string,...]] [edg=string[,string,...]] [--verbose] [--quiet]

### Flags:

-e
  Output map 'edge' of edges given a '1' in r.le.para/edge file
-u
  Output maps 'units_x' with sampling units for each scale x
-z
  Output map 'zscores' with standardized scores
--verbose
  Verbose module output
--quiet
  Quiet module output

### Parameters:

map=string
  Raster map to be analyzed
sam=string
  Sampling method (choose only 1 method):
  w = whole map u = units m = moving window r = regions
  Default: w
reg=string
  Name of regions map, only when sam = r; omit otherwise
att=string[,string,...]
  b1 = mn. pixel att. b2 = s.d. pixel att.
  b3 = min. pixel att. b4 = max. pixel att.
  Options: b1,b2,b3,b4
div=string[,string,...]
  d1 = richness d2 = Shannon d3 = dominance d4 = inv. Simpson
  Options: d1,d2,d3,d4
te1=string
  Texture method (choose only 1 method):
  m1 = 2N-H m2 = 2N-45 m3 = 2N-V m4 = 2N-135
  m5 = 4N-HV m6 = 4N-DIAG m7 = 8N
  Options: m1,m2,m3,m4,m5,m6,m7
te2=string[,string,...]
  Texture measures (required if te1 was specified):
  t1 = contagion t2 = ang. sec. mom. t3 = inv. diff. mom.
  t4 = entropy t5 = contrast
  Options: t1,t2,t3,t4,t5
jux=string[,string,...]
  Juxtaposition measures (weight file in r.le.para needed):
  j1 = mn. juxtaposition j2 = s.d. juxtaposition
  Options: j1,j2
edg=string[,string,...]
  e1 = sum of edges e2 = sum of edges by type (need edge file: r.le.para)
  Options: e1,e2

## DESCRIPTION

The r.le.pixel module contains a set of measures for attributes, diversity, texture, juxtaposition, and edge.
