摘要：The automation of 3D building reconstruction is an ongoing topic of worldwide research. Currently, cities all over the world are heavily engaged to create 3D city models for various reasons like town planning, urban climate and noise simulations, virtual tourism etc. Generally, companies are entrusted to generate such 3D city models. The current approaches of those companies are labour intensive and therefore cost intensive, since the reconstruction of each single building is based mainly on manual processing within a computer supported editing framework. The same holds for internet providers of 3D city models which offer tools for the interactive construction of 3D models (e.g. the SketchUp tool of Google Earth). In cooperation with the land registry and surveying office of the city of Bonn we developed an automated approach to 3D building reconstruction as well as a spatial information system for the maintenance of 3D city models. This contribution focuses on our approach on 3D building reconstruction which employs a model-based data fusion from aerial images, airborne laser scanning and GIS. Furthermore, we describe our spatial information system to maintain the 3D city models. The spatial information system is based on open source RDBMS and offers SQL-based spatial query functionality
