In this paper we describe how urban data from different system and application domains such as Computer Aided Design (CAD), Geographic Information Systems (GIS), and Building Information Models (BIM) can be integrated by a service-based virtual 3D city model system. The 3D viewer client allows users to access, to import, and to integrate semantic-enhanced information models from the CAD, GIS, and BIM domain that are provided within a service-based geodata infrastructure. The 3D viewer client represents the core component that implements a number of adaptors for various OGC web service types, manages the resulting virtual 3D city model based on CityGML, and can act itself as a higher-level service delivering integrated information. This approach shows how urban data from different scales, different domains, and different shareholders can be seamlessly integrated at visualization level and how corresponding services can be setup. The work is based on our development of an interoperable 3D viewer client within the CAD/GIS/BIM thread of the Web Services Initiative Phase 4 of the Open Geospatial Consortium.
