DescriptionRemotely sensed data for Southeastern United States (Standard Federal Region 4) are used to examine the scale problems involved in reporting landscape pattern for a large, heterogeneous region. Frequency distribu-tions of landscape indices illustrate problems associated with the grain or resolution of the data. Grain should be 2 to 5 times smaller than the spatial features of interest. The analyses also reveal that the indices are sensi-tive to the calculation scale, i.e., the unit area or extent over which the index is computed. This "sample area" must be 2 to 5 times larger than landscape patches to avoid bias in calculating the indices.
