The 3D topological relationship model of laneways is the basis of spatial analysis of generation, ventilation, transport, disaster modeling, etc. Based on analyzing the characteristic of traverse data, the laneways can be regarded as a line-domain network, and the 3D laneway topological model can be represented by 3D topological network graph. The method of spatial relationship reasoning is used to automatically build 3D laneway topological model. The 3D laneway topological data structure model is designed to support spatial reasoning. Finally, the 3D laneway topological model is achieved with SuperMap Object, and a research instance is provided in the paper.
