数字城市GIS分布式应用体系研究

Study of the GIS Distributed Application System for Digital City

本文分析了数字城市对GIS数据集成与应用服务的需求,提出了GIS分布式应用体系的框架,由网络体系、数据体系、技术支撑体系和应用服务体系组成,建立逻辑数据中心,利用元数据和多数据库管理系统,实现分布式异构空间数据的共享服务。

This paper analyses the digital city＇s demands for GIS data integration and application service, and presents a framework of GIS distributed application system, which is composed of network system, data system, technical system, application system and serving system. This system will build logic data center, adopt metadata and MDBMS, and achieve a sharing service of the distributed spatial data with different structure.
