Comparison of Viewsheds in Western Maryland

Comparison of the viewsheds for the Sideling Hill road cut in western Maryland and three large mine features. The planimetric area of the road cut is very small compared to the mines, but its topographic setting results in a very large viewshed area. Consequently, the viewshed-area-to-change-area ratio for the road cut is much higher than the mine ratios. The size of each area shown is about 32.7 kilometers east-west by 26.4 kilometers north-south.
