The efficient collection and presentation of geospatial data is one key task to be solved in the context of location based services. As an example, virtual landscape models have to be generated and presented to the user in order to realize tasks like personal navigation in complex urban environments. For an efficient model generation, different data sources have to be integrated, whereas an efficient application for location based services usually requires the use of multiple sensor configurations. The work on the generation and application of virtual landscape models described within the paper is motivated by a research project on the development of a generic platform that supports location aware applications with mobile users.
