Description

Landscape composition metrics

Patch density (PD)

Depicts the number of patches in every km2

Area-weighted mean patch size (AMPS)

Depicts average area-weighted patch size of each class

Largest patch index (LPI)

Represents the percentage of area occupied by the largest patch of a class

Landscape configuration metrics

Cohesion

Depicts connectedness among the patches of the respective class. A higher value indicates high aggregation among the patches

Contagion (CONTAG)

It is a measure of relative aggregation among the patches at the landscape level. Value ranges from ‘0’ to ‘100’. ‘0’ represents highly disaggregation and ‘100’ represents highly aggregation
