| 摘 要： | 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。

| Abstract: | Current 3D GIS attaches importance to the study of 3D space,which focuses on the study of the data organization of geometric 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. |
