Enhancing 3D City Models with Heterogeneous Spatial Information: Towards 3D Land Information Systems

Spatial and georeferenced information plays an important role in urban land management processes such as spatial planning and environmental management. As many of the processes are increasingly coined by participation of and collaboration between multiple stakeholders, a common medium capable of integrating different types and sources of spatial information is necessary. It is argued that 3D city models provide such a framework and medium into which heterogeneous information can be integrated. Therefore, the main research question of this contribution is to identify and develop methods for integrating heterogeneous spatial and georeferenced information into 3D city models in the context of urban land management. We present a prototype 3D Land Information System and a use case for the city centre of Potsdam, Germany. In addition, constraints within administrations regarding the systematic, sustainable use of such a system are discussed. 2 Lutz Ross, Jannes Bolling, Jürgen Döllner, Birgit Kleinschmit
