    MRDB approach to handle and visualise multiple DLM's in a consistent way
    (International Society for Photogrammetry and Remote Sensing, 2004) Anders, Karl Heinrich; Bildirici, İbrahim Öztuğ
    A Multi-resolution/representation-database (MRDB) can be described as a spatial database, which can be used to store the same realworld-phenomena at different levels of precision, accuracy and resolution. Furthermore these phenomena can be stored in different ways of presentation or symbolisation. In an MRDB, different views on the same physical objects or phenomena can be stored and linked. This variety of sights can stem from different views of the world, different applications, as well as different resolutions. These lead to differences in the objects as such, i.e. in the semantics and in the geometry. There are several reasons for introducing a 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 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, which is based on an Oracle database system as storage component and the ESRI ArcGIS system as the user interface to the MRDB. © 2004 International Society for Photogrammetry and Remote Sensing.
