Leve ls of Metrics
FRAGSTATS (v4.2 and earlier) computes 3 levels of metrics corresponding to: (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 section. 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 aggregation metrics. Note, cell-level
metrics are scheduled to be included in version 4.3.
