Ranking Features Based on Magnitude of Change
Each of the polygons in the topographic change inventory has numerous attributes associated with it. These attributes allow a ranking of features based on the magnitude of change, as measured by polygon descriptors (area and volume) and changes in terrain parameters (elevation, relief, slope, aspect). The ability to do such a ranking points out one of the advantages of producing spatially explicit change maps from geospatial data over broad areas: the effects of changes at specific locations can be quantified.
