基于MGE的勘测信息系统升级方法的研究

Study on the Upgrading Method of Survey and Investigation Information System Based on MGE

随着社会各界对大比例尺空间数据的获取、共享、建库和应用等方面要求的提高,基于MGE平台开发的广州市勘测信息系统,其图形与属性数据分离管理的数据管理模式在数据安全性、数据共享以及数据动态更新等方面已经不能满足当前数据服务的要求,面临升级与改造。文章针对广州市城市勘测信息系统的现状特点,提出了广州市城市勘测信息系统升级的解决方案。

With the improving requirements on the acquiring, sharing, database constructing, applying of large scale spatial data from all circles in the society, Guangzhou Fundamental Geographic Information System which developed based on MGE can not meet the requirement of current data services in data security, data sharing and data dynamic updating, and so on. The system is confronted with upgrading and reconstructing. Aiming at the status in quo and characteristics of Guangzhou Fundamental Geographic Information System, this paper put forward the upgrading solution of the system.
