城市地理信息服务平台体系架构

Geographic Information Service Platform on Urban Architecture

针对地理信息服务平台建设的部分关键技术问题进行研究。以地理信息的生产、建库、集成管理、分发利用流程为主线,重点研究平台建设的技术路线,实现以集中式基础地理空间框架数据库为基础,以分布式专题信息管理为基石,以网络化的地图与地理信息服务为表现形式,以电子政务内外网为依托,通过建立地理信息获取与维护体系、地理信息集成管理与共享体系和地理信息分发与服务体系三大体系结构,形成地理信息有机的集成管理、信息共享和开放式应用,实现地理信息服务平台体系架构,为各行业建立自己的专业地理信息服务平台参考。

The paper focused on the key problems of GIS service platform.We took the production,modeling,management and applications of geographic information as the main stream and flowchart,payed more attentions on techniques of platform to implement the integration of spatial database and the management of thematic information with distributed network.The geographic phenomena can be visualized through web with different networks,whether e-government network or public network.The system included three scenarios that's collection and maintain of geo-information,management of geo-information,share and distribution of geo-information.The system provided a foundational platform for applications of different fields.
