Perspective views of the road cut through Sideling Hill in western Mar

Perspective views of the road cut through Sideling Hill in western Maryland. The top image is derived from the NED and the bottom image is derived from the SRTM data (colors range from blue for the lowest elevations to red for the highest elevations within the scene). The viewing direction is toward the southeast. The arrow indicates the location of the cut through the prominent ridge. Without any adjacent terrain features to block the view, the road cut can be seen from many locations over long distances. Perspective views are useful to qualitatively portray the visual impacts of topographic surface changes.
