(P5) Perimeter

p_ij =    perimeter (m) of patch ij.

Description

PERIM equals the perimeter (m) of the patch, including any internal holes in the patch, regardless of whether the perimeter represents ‘true’ edge or not (e.g., the case when a patch is artificially bisected by the landscape boundary when a landscape border is present).[p_ij =intTrue+intBack+extTrue+extBack+extLike]

Comments

Patch perimeter is another fundamental piece of information available about a landscape and is the basis for many class and landscape metrics. Specifically, the perimeter of a patch is treated as an edge, and the intensity and distribution of edges constitutes a major aspect of landscape pattern. In addition, the relationship between patch perimeter and patch area is the basis for most shape indices.
