Abstract :
Since planar graphics can not meet the needs of precisely reflecting real spatial relationship between pipelines, it is necessary to build a 3D visualization system of urban pipe network. 3D spatial data model is the basis of data representation and spatial visualization. Based on the analysis of the features of urban pipe network and the requirements of the 3D model, a spatial data model for urban pipe network visualization system (UPNVS) is designed and organized by spatial metadata. The advantage of the spatial metadata is discussed in the paper. The application of the model in a real project shows that it is effective.
