ENT (landscape level)
Marginal entropy [H(x)]
lsm_l_ent(landscape, neighbourhood = 4, base = "log2")
landscape
: A categorical raster object: SpatRaster; Raster* Layer, Stack, Brick; stars or a list of SpatRasters.neighbourhood
: The number of directions in which cell adjacencies are considered as neighbours: 4 (rook's case) or 8 (queen's case). The default is 4.base
: The unit in which entropy is measured. The default is "log2", which compute entropy in "bits". "log" and "log10" can be also used.tibble
It measures a diversity (thematic complexity) of landscape classes.
