摘要：Within the paper the integration of 3D building models in the context of location aware services is presented by two exemplary applications. First the intuitive access to object related information within an urban environment is by telepointing is described. For that purpose terrestrial images are mapped against a 3D model of the environment based on direct georeferencing and a image based localisation of depicted buildings. The oriented image then allows for the access to information related to the depicted objects by pointing to the respective image sections. Secondly, the paper presents an approach for the generalisation of 3D building models with regard to the visualisation of urban landscapes. Especially for applications such as web-based 3D GIS and the presentation of virtual walk-throughs on mobile computing devices, these generated representations of the 3D models are a prerequisite in order to generate level of detail structures for real-time rendering
