Abbreviation

Description

Area

AREA

Area equals the sum area of each patch type (class). AREA > 0, without limit.

Number of patches

NP

NP equals the number of patches of the corresponding patch type (class).NP ≥ 1, without limit.

Area means

AREA-MN

AREA-MN equals the mean area of patches of the corresponding patch type. AREA-MN > 0, without limit.

Largest patch index

LPI

LPI equals the percentage of the landscape comprised by the largest patch. 0 < LPI ≤ 100

Landscape shape index

LSI

LSI is a landscape patch shape index which represents the degree of agglomeration in relation to shape complexity. LSI ≥ 1, without limit.
