ENN

Euclidean nearest neighbor distance (ENN) is perhaps the simplest measure of patch isolation. Here, nearest neighbor distance is defined using simple Euclidean geometry as the shortest straight-line distance between the focal patch and its nearest neighbor of the same class, based on the distance between the cell centers of the two closest cells from the respective patches.

CONTIG(Contiguity Index)

Contiguity index assesses the spatial connectedness, or contiguity, of cells within a grid-cell patch to provide an index on p

PARA (Perimeter-Area Ratio)

Perimeter-area ratio is a simple measure of shape complexity, but without standardization to a simple Euclidean shape (e.g., square). A problem with this metric as a shape index is that it varies with the size of the patch. For example, holding shape constant, an increase in patch size will cause a decrease in the perimeter-area ratio.
