An Improved LOS Method for Implementing Visibility Analysis of 3D Complex Landscapes

Abstract

This paper presents an efficient method for implementing visibility analysis on complex landscapes based on an improved LOS (line of sight) algorithm. The method not only determines the viewshed through capturing the geometric relationship between the target points and viewpoint. It also judges the visibility of the target points by the elevations. The… (More)
