摘要
数字地形分析是基于数字高程模型(DEM)进行地形分析的一种数字分析技术,是常规纸质地图分析、DEM应用范围的拓广和延伸。地形的可视化表达是地形地貌、景观建模、地形分析等领域的基本技术手段之一,通过和地形分析技术的有机结合,可使地形的表达更加逼真形象。本文简要论述了数字地形分析的基本内容和原理,总结归纳了地形三维可视化表达的相关模型。
Digital terrain analysis is a digital analysis technology for terrain analysis based on digital elevation model (DEM), is extension of conventional map-analysis and DEM applications. Visual expression is a basic technical means of the terrain topography, landscape modeling, terrain analysis and other fields, through organic combination with terrain analysis, the expression of terrain can be more realistic and vivid. This paper briefly discussed the basic content and principles of digital terrain analysis, summarized some models in 3D terrain visualization expression.
