lsm_c_np: NP (class level)

In landscapemetrics: Landscape Metrics for Categorical Map Patterns

NP (class level)

Description

Number of patches (Aggregation metric)

Usage

lsm_c_np(landscape, directions = 8)

Arguments

landscape	Raster* Layer, Stack, Brick, SpatRaster (terra), stars, or a list of rasterLayers.
directions	The number of directions in which patches should be connected: 4 (rook's case) or 8 (queen's case).

Details

NP = n_{i}

where n_{i} is the number of patches.

NP is an 'Aggregation metric'. It describes the fragmentation of a class, however, does not necessarily contain information about the configuration or composition of the class.

Units

None

Ranges

NP >= 1

Behaviour

Equals NP = 1 when only one patch is present and increases, without limit, as the number of patches increases

Value

tibble
