NAME

r.le.pixel - The r.le.pixel program contains a set of measures for attributes, diversity, texture, juxtaposition, and edge.
(GRASS Raster Program)

SYNOPSIS

r.le.pixel
r.le.pixel.help
r.le.pixel [-beuz] map=name [sam=name] [reg=name] [att=name[,name,...]] [div=name[,name,...]] [te1=name] [te2=name[,name,...]] [jux=name[,name,...]] [edg=name[,name,...]]

OPTIONS

Flags:

-b
Run in background.
-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.

Parameters:

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