Total edge (Area and Edge metric)

## Arguments

- landscape
A categorical raster object: SpatRaster; Raster* Layer, Stack, Brick; stars or a list of SpatRasters.

- 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.
