| 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。

| Abstract: | 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. |
