摘要
城市地下管网的综合规划和管理,正随着地理信息系统产业的发展,越来越受到人们的重视。而空间数据模型是任何地理信息系统设计的核心。在综合评述GIS空间数据模型研究的基础上,针对城市地下管线空间对象,研究了地下管网的特点,提出了实体几何法与三维拓扑的集成模型,并设计了系统概念模型、数据组织模型以及相应的数据存储结构。
Planning and managing cities＇ pipelines network underground become more and more important with the development of geographical information system. Spatial data model is the kernel of all geographical information systems. A integration of CSG and topological model for 3D GIS of cities＇ pipelines network underground is proposed based on summarizing spatial data models of GIS and researching on the characteristics of pipelines network underground, and the system＇s concept model, data organization model and data storage model are designed.
