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 actual standardization developments, we applied and extended the Symbology Encoding OGC-standard. The approach compromises processing, visualization with its symbolizers. The concept as well as some implementation-specific aspects are shown. Within a discussion some open topics and modelling issues regarding the geometry handling in 3D GIS are raised.
