View shed Analysis is a common function in most of the GIS software. A view shed identifies the cells in an input raster that can be seen from one or more observation locations. The analysis uses the elevation value of each cell of the digital elevation model (DEM) to determine visibility to or from a particular cell.
The analysis process is a useful tool to know how visible objects might be, what will be the view from a road etc. This tool creates a raster, recording the number of times each area can be seen from the input point or observer feature locations.
