Synthetic Textures for 3D Urban Models in Pededstrian Navigation

Since years the market of mobile navigation systems is growing enormously. Within this paper the goals and first results of the joint project “Mobile Navigation with 3D City Models” (MoNa3D; http://www.mona3d.de) are introduced. The project consortium consists of the University of Applied Science Stuttgart (coordinator), the University of Applied Science Mainz, the University of Bonn and the four companies Navigon, Teleatlas, GTA Geoinformatik, and Heidelberg Mobil. The aim of the project is to develop and evaluate the support of landmarks and 3D visualization in mobile navigation systems for pedestrian navigation as well as the “last mile” car navigation for instance from a parking place to the final destination. The two main goals of the project are to provide a cognitive semantic route description by using landmarks and secondly to make use of synthetic building facade textures along with a corresponding compression system for an efficient storage, transfer, and rendereing of 3D urban models. This paper focuses on the synthetic texturing and compression.
