Max/Min Path Visual Coverage Problems in Raster Terrain

Path visual coverage is the region which could be seen from the path in the terrain. This paper advances the concept of "average horizon " which represents the wide extent of the visual field of each path point to analyze and model the max and min path visual coverage problems, and resolves them utilizing simulated annealing algorithm based on the operation of viewshed amalgamation with pre-computed and stored viewshed information.
