      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.},
