A viewshed is a tool that urban planners and landscape architects use to understand what can be seen from specific locations. Think of it like taking a photo from a particular spot - everything you can see in that photo is part of the viewshed. Planners use this concept when deciding where to place buildings, protect scenic views, or preserve historic landscapes. For example, they might use viewshed analysis to make sure a new building doesn't block important views of a city landmark or natural feature. It's similar to sight line analysis or visual impact assessment, but viewshed specifically refers to the complete area visible from a given point.
