基于要素的城市地形图与管线数据库管理系统的设计与建设

The Design and Construction of Urban DLG and Pipeline Database Management System Based on Feature

以福州城市地形图与管线数据库管理系统的设计与建设为例,具体论述了在基于要素的空间关系型数据库模式下如何实现城市大比例尺地形图与管线数据的更新管理、对内如何提供测绘生产服务、对外如何提供数据应用和分发服务以及该系统与其他信息系统(如生产项目管理系统)之间的信息交互和互操作等问题。总结了系统开发过程中的关键技术以及该系统在信息化测绘技术体系中的定位和应用发展前景。

Based on the （（Fuzhou Urban DLG and Pipeline Database Management System）） of design and construc- tion example,This paper expounded How to realize the city large scale topographic map and pipe data management,How to provide nternalsurveying and mapping production services,How to provide data applications and distribution,How to realize the ~ystem and other information system（ e. g. Project Management Systme） of the interaction between information and interoperability. Meanwhile,this paper summarized the key technology in the process of system development ,the posi- tioning of this system in the information technology system of surveying and mapping,the application and development prospect of this system.
