Multi-representation databases with explicitly modelled intra-resolution, inter-resolution and update relations


Bobzien, Matthias; Burghardt, Dirk; Petzold, Ingo; Neun, Moritz; Weibel, Robert (2006). Multi-representation databases with explicitly modelled intra-resolution, inter-resolution and update relations. In: AutoCarto 2006, Vancouver WA, 26 June 2006 - 28 June 2006, 1-17.

Abstract

This paper presents a new approach combining multi-representation databases with the generalisation and update process. It leads to a tightly integrated model, which is implemented as a part of the existing cartographic GIS axpand. The approach is based on the mathematical concept of relations and, in particular, on the three different types of relations: intra-resolution, inter-resolution and up-date. Intra-resolution relations allow the representation of relationships between features within one resolution. Examples are partitions, neighbourhood and topology. The inter-resolution relation represents the relationship between features of different resolutions. This originates from a generalisation or matching process. The update relation describes temporal changes of features. After a detailed theory about the introduced relation types the paper continues with a discussion of their similarities and differences with focus on implementation in a multi-representation database. Finally some exemplary results of the integrated model are presented.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
