lsm_l_np(landscape, directions = 8)
Raster* Layer, Stack, Brick or a list of rasterLayers.
The number of directions in which patches should be connected: 4 (rook's case) or 8 (queen's case).
tibble
$$NP = N$$ where \(N\) is the number of patches.
NP is an 'Aggregation metric'. It describes the fragmentation of the landscape, however, does not necessarily contain information about the configuration or composition of the landscape.
