A viewshed marks every point visible from an observer, hidden behind intervening ridges. Scanning outward, a point is seen only if its angle above the horizontal exceeds every closer obstacle — so terrain shadows fall behind hills. Raising the observer reveals far more. It is essential for siting cell towers, wind turbines, scenic overlooks, and military positions.
