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

KEYWORDS

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,...]] [--help] [--verbose] [--quiet] [--ui]

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
--help: Print usage summary
--verbose: Verbose module output
--quiet: Quiet module output
--ui: Force launching GUI dialog

Parameters:

map=string [required]: 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
