城市管网三维建模技术研究

Research on 3D Modeling Technologies of Urban Pipe Network

设计了城市管网三维模型的逻辑结构,介绍了基于Super Map的管网三维建模技术,解决了管网拓扑模型中的假节点、流向等问题,并以大连石化矿区燃气管网建模为例,详细介绍了在Super Map中三维建模技术的具体步骤。

This paper designed the logical structure of the 3D model for urban pipe network, and introduced 3D modeling technology of pipe network based on Super Map, in order to solve the issues of pipe network topology processing, such as fake nodes, the flowing of models and so on. And then, taking Dalian petrochemical mine gas pipe network modeling for example, the paper introduced the specific steps of 3D modeling technologies in SuperMap.
