摘要:Multi-scale representation and analysis of topology is playing a growing role in Photogrammetric Image Analysis. However, the standardisation of multi-scale topological data models is still at its beginning. Furthermore, the multi-representation of geo-objects poses new challenges, resulting in the development of Multi-Representation Databases. In this article the realisation of a general model based on oriented hierarchical d-Generalised Maps to represent and analyse topology in MRDB is described in detail. The model can be used as a data integration platform for 2D, 3D, and 4D topology. Examples of elementary and complex topological operations for multiple representations are presented. An application example with 2D cartographic datasets from Hannover University shows the feasibility of the new approach. Finally, an outlook on future research is given
