Styling geovisualizations means to control the geovisualization process, i.e., to define which geoinformation to include and how to visualize them. It is a crucial aspect for enabling flexible and adaptable geovisualization systems and applications as it allows authors and users to influence the visual appearance of the geovisualization and so to adapt it to specific tasks and preferences. Especially for the service-based implementation of geovisualization systems, it has to be specified how a service consumer can define the visual appearance of a geovisualization which might base on distributed heterogeneous geoinformation and might be synthesized by the combination of independent geovisualization services. This paper describes the styling of three-dimensional geovisualizations in two scenarios. First, a Web Perspective View Service (WPVS) for the generation of high-quality visualization of domain specific building information within its GIS context is described. Second, the Web View Annotation Service (WVAS) and its combination with a WPVS for the synthesis of textual annotated views are introduced. Both implementations are demonstrated for a 3D campus model.
