lsm_l_te: TE (landscape level)

In landscapemetrics: Landscape Metrics for Categorical Map Patterns

TE (landscape level)

Description

Total edge (Area and Edge metric)

Usage

lsm_l_te(landscape, count_boundary = FALSE)

Arguments

landscape	Raster* Layer, Stack, Brick, SpatRaster (terra), stars, or a list of rasterLayers.
count_boundary	Include landscape boundary in edge length

Details

TE = \sum \limits_{k = 1}^{m} e_{ik}

where e_{ik} is the edge lengths in meters. TE is an 'Area and edge metric'. Total edge includes all edges. It measures the configuration of the landscape because a highly fragmented landscape will have many edges. However, total edge is an absolute measure, making comparisons among landscapes with different total areas difficult. If count_boundary = TRUE also edges to the landscape boundary are included.

Units

Meters

Range

TE >= 0

Behaviour

Equals TE = 0 if all cells are edge cells. Increases, without limit, as landscape becomes more fragmented

Value

tibble
