Abstract
This paper presents some applications of mobile map technology utilising an MRDB (multi-resolution/-representation database). An MRDB can be described as a spatial database, which can be used to store the same real world phenomenon at different levels of thematic and geometric detail. Additionally the corresponding objects in the different levels are linked. Case studies of utilising an MRDB in combination with WFS (Web Feature Service) have been implemented and will be presented in this paper. To compensate the limitations of the small display of mobile devices multiscale maps are created. The scale will decrease continuously starting in the centre up to the map border, like a magnifying glass effect. Additionally in the centre of the map the built-up areas are exchanged by buildings. Another use of the MRDB is to emphasise special objects like landmarks or points of interest inside the map. These objects of interest are presented in a higher LoD (Level of Detail) than the other objects to direct the attention of the user to the important facts of the map and to design a clear visualisation. The MRDB can be helpful to support these kinds of presentations and applications as it maintains all the necessary data (levels of detail) and also the necessary links between these levels. This study is part of GiMoDig, a European project that aims at developing methods for spatial data distribution from national primary geo-databases to mobile users.
