hsp: Hierarchical Slope Position

Description

Calculates a hierarchical scale decomposition of topographic position index

Usage

hsp(
  x,
  min.scale = 3,
  max.scale = 27,
  inc = 4,
  win = "rectangle",
  normalize = FALSE
)

Value

raster class object

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)
