Viewshed analysis is a computational algorithm that delineates a viewshed, the area that is visible (on the base terrain surface) from a given location. It is a common part of the terrain analysis toolset found in most geographic information system (GIS) software. The analysis uses the elevation value of each cell of the digital elevation model (DEM) to…
