摘要：In this paper we are introducing analytical 3D views as a means for effective and understandable information delivery, using virtual globes and the third dimension as an additional information carrier. Four case studies are presented, where information extraction results from very high spatial resolution (VHSR) satellite images has been conditioned and (dis-)aggregated to certain spatial aggregation units. These case studies are embedded in the context of (1) urban life quality assessment (Salzburg/Austria) (2) contingency planning (Harare/Zimbabwe) (3) emergency response (Lukole/Tanzania) and (4) disaster management (faked crisis scenario/Germany). The results are made available in different virtual globe environments, using the high spatial resolution contextual data of these virtual globes (satellite imagery, aerial photographs, auxiliary geodata) as valuable additional context information. Both day-to-day users and high-level decision makers are addressees of this kind of conditioned information. The degree of abstraction required for understanding a complex analytical content is balanced with the easiness and the appeal by which the context is conveyed
