Graphical user interface.--FRAGSTATS analyses are parameterized via a graphical user interface which allows the user to tailor each run to their specific needs.
Command line execution.--FRAGSTATS can be executed from a command line to allow for execution from within another program (as an external execution)
Patch-based metrics.--FRAGSTATS computes numerous metrics that describe the structure of individual patches, classes or collections of patches of the same type, and the entire landscape mosaic for categorical patch mosaics.
Cell-based metrics.--FRAGSTATS (scheduled for inclusion in version 4.3) will compute a variety of cell-based metrics that describe the spatial structure of the local neighborhood of individual cells without regard to patch membership.
Surface metrics.--FRAGSTATS (scheduled for inclusion in version 4.4) will compute a variety of surface metrics that describe the spatial structure of continuous surfaces (i.e., landscape gradients).
