基于ArcGIS的三维建筑日照时态模拟

以福州大学怡山校区为例,在ArcGIS 10环境中,结合SketchUp构建三维建筑模型,对建筑物接受日照和产生阴影遮挡情况进行三维可视化时态模拟研究,提出了无需插件的MultiPatch三维模型创建思路以及三维建筑的日照分析方案。研究结果不仅可为城建规划部门及居民提供快捷可靠的科学日照分析手段,而且拓展了三维建筑模型在GIS中的应用。

Temporal Simulation of Sunlight on Buildings Based on ArcGIS

This paper took Yishan campus of Fuzhou University as an example to study the methodology for temporal simulation of direct sunlight on buildings under ArcGIS 10 environment by using SketchUp to create the 3D building models. In this study, an efficient method of creating 3D building MultiPatch models without the plug-ins between ArcGIS and SketchUp, and a scheme of sunlight and shadows analysis in ArcGIS were proposed. The results of this study not only depicted the sunlight received and shadows caused by the 3D buildings at different time in a vivid visualization way, but also expanded the application of 3D building models in GIS field.
