摘要
针对当前管线系统存在重复建设、数据维护困难的问题,分析了基于数据共享的多级地下管线信息系统建设的必要性,提出了从专业管线信息系统中概括出综合管线的相关信息的思路,探讨了基于数据共享的多级地下管线信息系统的数据模型及其技术难点问题,设计并开发了基于ArcSDE的分布式管线系统,从而实现了两种管线系统的数据共享,有效避免了管线系统的重复建设。
Aiming at the shortcoming of repetitious construction and hard to maintain the data of present pipelines GIS, this paper analyses the necessity of constructing a mutilevel underground pipeline GIS for cities based on data sharing. An idea that generalizes the information of synthetic pipelines from specialised ones; the data model of mutilevel underground pipeline GIS for cities based on data sharing; the design and development of distributed pipeline GIS system based on ArcSDE are presented. Thus, the data sharing between two pipeline systems has realized and therefore, the repetitious construction is effectively avoided.
