Abstract
With the increasing availability of small mobile computers, there is also an increasing demand for visualizing cartographic objects on those devices. Prominent applications are location based services in general, and car and pedestrian navigation in particular. In order to be able to offer both detail and overview of a spatial situation, the devices have to provide flexible zooming in and out in real-time. The presentation of spatial data sets in different zoom levels or resolutions is usually achieved using generalization operations. In this paper, we will descri be an approach to decompose generalization methods into elementary operations that can then be implemented in a continuous way. For example in the case of displacement, an object will not simply jump from one position to the other, but slowly shifted from its original position to the new one. In the case of simplification of building ground plans, the elementary operations e.g. care for removing extrusions or intrusions of buildings, as well as offsets.
