Hierarchical Slope Position
Calculates a hierarchical scale decomposition of topographic position index
hsp( x, min.scale = 3, max.scale = 27, inc = 4, win = "rectangle", normalize = FALSE )
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) |
raster class object
if win = "circle" units are distance, if win = "rectangle" units are number of cells
