地理信息二三维一体化模型MVC-G的构建技术

Construction Technology of MVC-G Model for 2D-3D Integration of Geo-information

为了满足当前地理信息数据表达需要，解决数据存储、操作一致性的问题，本文对地理信息二三维一体化进行研究。通过分析二三维一体化的结构和数据特点，在模型一视图一控制器一地理信息的体系下构建了二三维一体化的MVC-G集成框架模型，研究了二三维一体化所需数据模型和数据结构，并从二三维一体化数据应用机理出发，制定了统一机制，为高效利用和统一管理数据提供借鉴。

In order to meet current requirements of geo-information data representation and solve the consistency problem of data storage and operation, the 2D-3D integration of geo-information is studied in this paper. By analyzing the structure and data feature, a MVC-G integrated frame model of 2D-3D integration is set up within the framework of model/view/controller/geo-infor- mation. The corresponding data model and structure are studied, and a uniform 2D-3D integration data application mechanism is established, which will provide reference for efficient data application and management.
