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

terra SpatRaster class object of slope position

Arguments

x

A terra SpatRaster class object

min.scale

Minimum scale (window size)

max.scale

inc

Increment to increase scales

win

Window type, options are "rectangle" or "circle"
