Research on Integration of Multi-source BIM Models Based on GIS Platform

Aiming at solving the problems of low success rate and low efficiency in converting BIM models to GIS platform, this paper proposes a multi-source model integration and publishment method based on two main software, i.e., Bentley Microstation and Weijingxing CityMaker. First, this paper analyzes the traditional data exchange methods, and gives a recommended method to convert multi-source models to one format, i.e., DGN. Second, it proposes a data analysis and transformation method. This method converts format DGN to FDB, which is to realize the conversion of BIM models to GIS models efficiently. Third, the integrated model in the Weijingxing CityMaker GIS platform is tiled and published. Finally, the Shenzhen Qianhai Project is used as a case to verify the feasibility of the method. The method can integrate BIM models into the Weijingxing CityMaker 3D GIS platform efficiently and accurately, and has the potential to realize the integrated and centralized display of the massive urban-level model.
