摘要
三维可视化理论与技术的引入使得传统静态的、平面的地图向动态的、三维的方向发展,地图的三维可视化正成为GIS与数字制图领域一个新的研究课题。本文主要研究场景多尺度表达、顾及地形(即基于DEM)的建筑、植被、道路、水系等各主要要素的三维模型的建立及其显示、可视性分析。文章最后对三维可视化技术在基于城市规划领域的规划展示、设计对比、日照分析、历史变化等方面的应用作了探讨。
The introduction of the theory about three-dimensional visualization technology, changes the traditional static and plane map to the dynamic and three-dimensional map. Map of three-dimensional visualization becoming a new field of research in GIS and digital mapping. This paper studies the expression of multi-scale scenarios, taking into account the terrain （which is based on DEM） of the buildings, vegetation, roads, water and other major elements of the three-dimensional model and its display, visibility analysis. Finally, three-dimensional visualization technology in the field of urban planning based on planning exhibition, design comparison, sunlight analysis, historical change and the application are discussed.
