3D Multi Representations of Building for Mobile Augmented Reality

1. Introduction There are growing needs for geospatial information everywhere, at anytime, adapted to the user profile, location and context. Getting the right information at the right time and the right place is key in numerous applications (emergency and risk management, military defence, urban navigation, etc.). The fact that geomatics is required whenever spatial decision-making is involved makes these needs even more manifest. Although progresses have been made for the past few years in the field of Geographic Information System (GIS), the current technology is still not able to offer true dynamic, interactive, ubiquitous and pervasive representation of space.
