ABSTRACT
ABSTRACT: In this paper we present an approach for the visualization definition and control of 3D city models enabling a more flexible and map-orientated presentation of city scenes. Following the actual standarization developments, we applied and extended the Symbology Encoding OGC-standard. The approach compromises processing and visualization with its symbolizers. The concepts as well as some implementation-specific aspects are shown. Within the discussions some open topics and modelling issues regarding the geometry handling of 3D GIS are raised.
