Zusammenfassung

A Multi-resolution/representation-database (MRDB) can be described as a spatial database, which can be used to store the same real-world-phenomena at different levels of precision, accuracy and resolution. Furthermore these phenomena can be stored in different ways of presentation or symbolisation. There are several reasons for introducing an MRDB: On the one hand it allows a multi-scale analysis of the data: Information in one resolution can be analysed with respect to information given in another resolution. On the other hand a major reason for National Mapping Agencies to investigate and implement MRDB is the possibility of propagating updates between the scales, which is also called ?incremental generalisation?. In a cooperation with the German Federal Agency for Cartography and Geodesy (BKG) we are developing at the institute of cartography and geoinformatics (ikg) an automatic model generalisation und update (data revision) system for the German ATKIS (Authoritative Topographic-Cartographic Information System). In this paper we will describe the structure and functionality of our ATKIS MRDB, and the planed extension to store cadastral and 3D building information.
