An Integration Method of Road Designing BIM Model and 3D GIS Data

CHEN Guang;XUE Mei;LIU Jinbang;HE Xingfu;ZHOU Zhihai;Chongqing Survey Institute;  
Aiming at the shortage of existing municipal road model exchange standards, as well as the geometric and semantic information missing in the integration of BIM design model and GIS model, a method of integration of BIM design model and GIS data are proposed in this paper. The core of the method is redefining the extended road design model based on the CityG ML model. The method implements integrating and expressing of road model and GIS data through the process of factor semantic analysis, geometric model transformation. In this paper, the surrounding municipal road design project of Yinchao Club in Jiulongpo District of Chongqing city is taken as an example for the integrating experiment of road BIM design model and 3 D city model data. The experimental results show that the proposed method can preserve the entire structure, the cross section characteristics and the topological information of road sections. The extended road design model integrally stores and expresses the road design elements. This method has a broad prospects in road planning and design.
