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

Examples

# NOT RUN {
  library(raster)
  data(elev)
  hsp27 <- hsp(elev, 3, 27, 4, normalize = TRUE)
  plot(hsp27)
 
# }
# NOT RUN {
