terrain analysis
definition: Terrain analysis uses elevation data, especially digital elevation models (DEMs), to characterize the bare terrain surface and, in most cases, link terrain properties to the natural or built environment. Closely associated with spatial analysis, terrain analysis is a fundamental component of geographic information science and provides solid support for a wide variety of GIS modeling and analysis activities.
