Cumberland VCE Slope 2002

Slope is a measurement of the incline, or the steepness, of a surface. Slope was derived from the TIN (see description under DTM on page 6). Slope was generated as a percent slope (which is the rise divided by the run multiplied by 100). The illustration to the right shows slope classifications and hydro (left side) and slope classifications with aerial photography and hydro. Slope layers are often used in site suitability analysis to support economic development, community planning or zoning, agricultural suitability analysis, precision agriculture, natural resource management, and water retention and surface water runoff modeling.The Virginia Geospatial Extension Program developed the slope layer using the TIN. It is suitable for general (regional) planning purposes and should be verified.
