The integration of socioeconomic and ecological variables
discussed in Section 1.1 is accomplished
spatially through the use of gridded maps. Individual
maps may represent a single data theme
which describes physical landscape attributes (e.g., land cover,
slope, soil type), spatial features (e.g., distance relationships,
adjacency rules), the results of socioeconomic and
ecological processes (e.g., changes in real estate values, species
abundance, and erosion), and land-ownership characteristics
(e.g., tract size, shape, and history).
