AbstractMany GIS applications require efficient algorithms to manipulate huge volume of data about terrains stored in external memory. One of these applications is the viewshed computation which consists in obtaining the points that can be viewed by a given point. In this paper, we present an efficient algorithm to compute the viewshed on huge terrains stored in external memory.
