| 摘 要： | 主要研究如何在三维管线模型中引入时间信息,构建基于对象的原始信息和变化信息的映射关系,将含有时间戳的变更信息存入数据库中,建立管线时空数据模型.实现三维管线数据的动态管理,可以浏览和编辑最新的管线数据,也可以通过时间轴来查看任意历史时刻的管线数据.

| Abstract: | How to bring time information into 3D pipeline model was studied,object-based mapping relationship between original and varied information was constructed,change information including time-stamp was stored in database and pipeline spatiotemporal data model was built.The system realized dynamic management of 3D pipeline and users could look into and edit up-to-date pipeline data and browse pipeline data at any historical time. |
