Spatial analysis and 3D simulation of underground pipe network based on arcGIS

To resolve the problem that underground pipe network is large, complex, and difficult to manage, the management model based on ArcGIS was used. This paper aimed to transform the traditional data types of underground pipe network to a new type based on ArcGIS and to make statistical analysis and thematic maps output to the attribute datas for all underground pipes mainly including water supply network and drainage network. Through the analysis of pipe network visualization model implementation to build the spatial data model of three-dimensional pipe network, the automatic model from 2D to 3D would be achieved, then the new ways to realize the 3D visualization of urban underground pipe network would be provided. Taking the underground pipe network of a city as an example, the management system based on ArcGIS was built. The system running results show that the system could achieve the digital management of underground pipe network for the city and improve the management efficiency of the entire system.
