基于CityGML的数字城市快速建模研究

Research on Rapid Modeling of Digital City Using CityGML

研究了基于CityGML的多层次细节3D城市模型快速建模方法,并将其结合到3DUGIS中用于数字城市建设。建模过程中考虑空间关系、拓扑关系和语义信息,建模过程自动化程度高,能够在三维空间直接进行空间分析,方便海量数据的交换与数据挖掘。并给出了上海世博园区三维信息系统结合具体应用案例。

This paper researched on the rapid modeling method of the multi-level of details （LODs）3D city model using CityGML and its integration into 3DUGIS for the construction of digital city. Considering spatial relations, topological relations and semantic information in the process of modeling, and the automation of modeling in a high level, and it can do spatial analysis in three-dimensional space directly, and facilitate the exchange of huge amounts of data and data mining. The Shanghai World Expo three-dimensional information system gives a specific application.
