FRAGSTATS does not limit the scale (extent or grain) of the landscape subject to analysis per se, although there are memory limitations on the size of the grid that can be loaded. However, the distance- and area-based metrics computed in FRAGSTATS are reported in meters and hectares, respectively. Thus, landscapes of extreme extent and/or resolution may result in rather cumbersome numbers and/or be subject to rounding errors. However, FRAGSTATS outputs data files in ASCII format that can be manipulated using any database management program to rescale metrics or to convert them to other units (e.g., converting hectares to acres).
