摘要
针对城市地下管线数据的特点以及不同部门管线数据结构不一致问题,利用Geodatabase表达地理空间对象的优势,以地下管线全生命周期为主线,设计了一种基于Geodatabase的城市地下管线统一数据模型,并进行了管线数据库构建的标准化研究,实现了多源异构管线数据的一体化存储,分析了该模型在地下管线编辑建库系统中的应用情况,实现了标准化的管线信息建库和管理,为城市地下管线信息共享提供新的思路。
This paper designed an urban underground pipeline data model based on Geodatabase, which aimed at the characteristics of urban underground pipeline data and its advantage of expressing geospatial objects expression. According to inconsistencies problems to underground pipeline in different departments, the paper designed a standard business-oriented database structure, which realized an integrated storage of multi-source heterogeneous pipeline data. Finally, the paper analyzed the application of model in pipeline editing system. This system realized the standardized of pipeline information building and managing, which would be a good thought for sharing urban pipeline information.
