Unterstützung virtueller Spaziergänge in Stadtmodellen durch ein adaptives 3D-GIS-Streamingframework

This thesis presents a streaming framework for 3D geo information systems. The main challenge lies in the efficient distribution of large amounts of GIS data. Focus is set to fast delivery and visualization of content as well as to maintaining full quality and authoring capability of GIS data. As technological platform, the CityServer3D of the Fraunhofer Institute for Computer Graphics is used. In the first step, existing approaches in local and remote rendering are examined for transferability and used as basis. In order to define overall goals, needs and requirements of different stakeholders are considered. Besides functional requirements the user experience and overall usability plays an important role. Subsequently, this thesis presents a detailed solution. Essential part of the concept is the specification of modules. By this means, the framework can be used in different application contexts. As a proof of concept, a prototypical implementation of the specification is introduced. The last part of this work deals with the evaluation of the approach. Therefore, a usabilty test as well as technical aspects are considered to show strengths and weaknesses of the framework
