当前的3维GIS重视3维空间方面的研究。重点是研究3维空间的几何对象的数据组织、操作方法以及查询分析等内容。本文通过对3维空间数据模型的研究,建立了一种基于CityGML语义的以建筑物为主的城市目标3维空间数据组织方法。这种方法丰富了城市3维空间数据建模,尤其对3维中的城市目标查询、统计和分析奠定了良好的基础。

Current 3D GIS attaches importance to the study of 3D space, which focuses on the study of the data organization of geomet- ric object, the method of operation, and query and analysis of 3D space. Through the study of the data model of 3D space, this paper sets up a data organization method of 3D space focusing on building based on CityGML semantics, which adds to the methods of city 3D space modeling and especially lays a good foundation for the target query, statistics and analysis of 3D city.
