Zusammenfassung: 
The modelling and management of topology plays an increasing role in Photogrammetry, Remote Sensing and GIS. In new application fields such as 3D city models, 3D navigation systems and early warning of geological events, multi-scale topological data models are needed. In this article a unified model for topology is proposed, based on oriented d-Generalised Maps (2 <= d <= 3) to represent topology in Multi-Representation Databases (MRDB). Topological data structures and operations are presented in detail. The model can be used as a data integration platform for 2D and 3D topology, as well as for the representation and management of topology in a multi-resolution GIS. An application example, management of topology in a multi-scale land-use map based on aggregation, shows the feasibility of the new approach.
