## 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.
