Levels of Metrics

FRAGSTATS computes 3 groups of metrics. For a given landscape mosaic, FRAGSTATS computes several metrics for: (1) each patch in the mosaic; (2) each patch type (class) in the mosaic; and (3) the landscape mosaic as a whole. These metrics are described in detail in the FRAGSTATS Metrics documentation. In addition, FRAGSTATS computes the adjacency matrix (i.e., tally of the number of cell adjacencies between each pairwise combination of patch types, including like-adjacencies between cells of the same class), which is used in the computation of several class- and landscape-level metrics.
