BIM/GIS integration offers new possibilities for the construction industry by using rich semantic building models of BIM in GIS environment and thereby providing context to the building and its surrounding area. BIM/GIS integration is facing many challenges that it needs to overcome, these are for the most part a lack of data control. This Master Thesis proposes a new approach for integrating BIM and GIS based on Model View Definition (MVD) and Profiling Geospatial Application Schemas. By providing a detailed review on current BIM/GIS integration methods and system architectures, several gaps in research can be pointed out. These mostly revolve around a lack of data control, information overflow, and privacy issues. As a solution for these current challenges the thesis proposes a new system architecture approach revolving around Industry Foundation Class Model View Definition (MVD) and Geospatial Profiles. A detailed comparison between MVD and Geospatial Profiles was conducted by comparing their qualities regarding data validation, data model restriction and extension, attribute and relationship customization, and geometry customization. This also included comparing XML transformation capabilities, documentation generation and a short software performance comparison. To test the capabilities of MVD and Geospatial Profiles several use case scenarios were modeled based on current BIM/GIS use cases. It is shown that the proposed tools serve as a viable solution for solving current BIM/GIS integration challenges, models could be filtered down to a lower Level of detail to avoid information overload. In addition, it is possible to share only specific building components to solve the issue of unauthorized access as well as check geometries of certain building parts, attributes and attribute values. The thesis proposes and creates a system architecture designed around MVD and Geospatial Profiles. It is tested together with the use case scenarios. IFC and CityGML data is stored on respective databases BIMserver and 3D CityDB and can be accessed using MVD transformed to mvdXML and Geospatial Profile transformed to XMI in a combination with FME. This serves as a final proof of concept and validated that the proposed tools in combination with a capable system architecture are effective at negating issues regarding data control, information overflow, and privacy.     «
