海量3维数据高效组织及集成研究

随着“数字城市”的推进，3维地理信息系统得到快速发展和广‘泛应用，产生了海量的3维地理空间数据，对3维空间数据的集成管理、并发访问、数据安全研究成为热点．市场对3维仿真系统和地理信息系统融合和统一需求日益迫切。针对“3维数字城市”建设新需求，本文在海缝3维场景组织、空间索引建立和基于关系数据库的存储等方面开展研究．为海量3维空间数据组高效组织和集成管理提供了一条有效途径。

Research on Effective Organization and Integration of Massive 3D data

With the popularity of 3D digital city, 3D GIS has been rapidly developed and widely used, which produces massive 3D space data. It is a hotspot to research on integration management, concurrent accessing and security of 3D data. The demands of 3D simulation system and GIS integration is increasing. For the construction of 3D digital city, this paper introduces methods for massive 3D scene organization, space index building and data persistence based on RDBMS, which provides an efficient solution for 3D space data organization and integration.
