Efficient Geo-Visualization Tools

The establishment and visualization of large, reality-based 3D terrain and city models has received significant attention over the last few years. However, the recent progress in 3D data capturing generated very huge and complexe 3D models. This poster presents tools for geo-visualization based on multi-resolution representations of different objects (terrain, buildings, vegetation, etc). Thanks to these scalable and compressed representations, web-based visualization can now be envisaged. We describe here one of the first solutions to fly over very huge urban environments in real-time, i.e. adapted to network-based visualization.
