lsm_l_joinent function

JOINENT (landscape level)

Joint entropy [H(x, y)]

lsm_l_joinent(landscape, neighbourhood = 4, ordered = TRUE, base = "log2")

Arguments

• 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.
• ordered: The type of pairs considered. Either ordered (TRUE) or unordered (FALSE). The default is TRUE.
• base: The unit in which entropy is measured. The default is "log2", which compute entropy in "bits". "log" and "log10" can be also used.

Returns

tibble

Details

Complexity of a landscape pattern. An overall spatio-thematic complexity metric.

Examples

landscape <- terra::rast(landscapemetrics::landscape)
lsm_l_joinent(landscape)
