Abstract
For the sophisticated spatial relationships of the urban underground pipeline networks, 3D visualization technology has become widely used for management and maintenance purposes of these types of underground utilities. With the increasing number of pipeline incidents, there is an urgent need for effective solutions for improving the management of urban underground pipe networks. In this paper, through a thorough analysis of the pipeline network management, a 3D urban underground pipe network system (3D UUPNS) was designed and implemented by using SuperMap.Net. The 3D models of the pipeline network and ground buildings are rendered by using SuperMap RealSpace Library, with 3D models of ground buildings being cached into OSGB format. Some analysis functions such as excavation analysis and section analysis, have been developed to support the management and operations of underground pipelines.
