hsp
From spatialEco v1.3-2
by Jeffrey S Evans
Hierarchical Slope Position
Calculates a hierarchical scale decomposition of topographic position index
Usage
hsp(
x,
min.scale = 3,
max.scale = 27,
inc = 4,
win = "rectangle",
normalize = FALSE
)
Arguments
- x
Object of class raster (requires integer raster)
- min.scale
Minimum scale (window size)
- max.scale
Maximum scale (window size)
- inc
Increment to increase scales
- win
Window type, options are "rectangle" or "circle"
- normalize
Normalize results to 0-1 scale (FALSE | TRUE)
Value
raster class object
Note
if win = "circle" units are distance, if win = "rectangle" units are number of cells
