A mobile 3D archipelago
Antti Nurminen · 2007
Geospatial virtual environments are real-time rendered 3D representations of geographical data. Until now, such GeoVE's have existed only on desktop machines. For the mobile user, a GeoVE can function as a 3D map, an easily recognizable visualization of the environment. In this paper, we present the development of such an application, suited for archipelago environments. The application is based on preprocessed topographical map data including navigational point objects. Assuming poor wireless network connections on the case area, this data is compressed and stored locally on a mobile device. The interaction scheme aims to lower the effort in developing and maintaining an accurate cognitive map of the environment. Map data preprocessing, compression and visualization in context of navigation are discussed. Performance and preliminary user feedback are presented.
