Abstract

On the one hand, the extent, modeled detail and accuracy of virtual landscapes, cities and geospecific content is rapidly increasing. Realtime visualizations based on geometric levels-of-detail (LODs) allow the user to explore such data, but up to now, the methods of interaction are very low-level. On the other hand, we have semantic categories for the objects which are modeled in ontologies. We propose an approach which allows to combine the advantages of both, realtime visualization techniques and semantic hierarchies, in a single application without establishing an explicit link. That way, we can achieve semantic interaction without interfering with the rendering techniques which is crucial for performance on large datasets. Moreover, we are able to exchange geometric and semantic models independently of each other.
