We present a platform for developing mobile 3D map navigation interfaces in highly occluded urban environments. The platform enables use of realistically textured city models in mobile devices such as PDA's and smart phones without 3D hardware, being able to render entire city centers at interactive rates. The platform supports network-distributed annotation of the environment with location-based information. Texture resolution can be varied per building. Maneuvering is not restricted, allowing implementation of any navigation metaphor. Efficient collision avoidance is provided. Key optimization methods, the overall system and supported features are presented along with guidelines for efficient modeling. Generic feedback from a focused field experiment is discussed.
