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