| 摘 要： | 地形可视性分析是太阳辐射分析、通讯信号场强分析、军事战场环境分析等应用领域中的核心问题。在现有可视性分析理论基础上,指出建立统一的地形可视性分析模型的必要性和重要意义。针对许多应用问题在方法与原理上的共性,提出一个统一的分析模型,对基于DEM地形可视性所涉及到的各个因素进行合理分类。

| Abstract: | The terrain visibility analysis is the core issue in some application domains such as the solar radiation analysis,communication signals intensity analysis,battlefield environment analysis.On the existing visibility analysis theory foundation,this paper points out the necessity and the vital significance to establish a uniform terrain visibility analysis model.In view of the commonness of the method and the principle in many application questions,it proposes a uniform analysis model.Each factor involved in the terrain visibility analysis based on DEM is classified reasonably. |
