| Summary: | 碩士 === 國立交通大學 === 土木工程系所 === 104 === Building Information Model (BIM) bears high details in geometric and semantic information of buildings; while Geographic Information System (GIS) stores and manages geospatial information of cities. Although they were developed from different domains, they both feature the semantic information and contribute to virtual 3D models. Recently, BIM and GIS have been considered serving complementary purposes according to many studies; thus their integration has been drawing much attention in order to promote data interoperability. This research proposed direct conversion schemes from BIM/Industry Foundation Classes (IFC) to OGC CityGML and to OGC IndoorGML. The CityGML conversion includes (1) establishment of BIM model and IFC file, (2) coordinate transformation, (3) conversion of geometric and attribute information and (4) generation of different Level of Detail (LoD) models. And the IndoorGML conversion involves (1) data preprocessing and (2) conversion of topological information into GML network. The experimental results suggested successful auto-generation of the LoDs of CityGML and IndoorGML dual space models from the BIM/IFC model. Moreover, the converted models were verified their accuracy and integrity in terms of geometric, attribute and entity phases. In the last of this study, the applications of the integrated models were demonstrated to explore potential markets.
