Percentile

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
