A combination of new projection technology, fast graphics cards and Linux PCs have made it possible to provide a stereo projection system that is much more affordable than previous commercial solutions. The GEOWALL project makes use of these projection systems to visualize structure and dynamics of the Earth in stereo to aid the understanding of spatial relationships. A good understanding of spatial relationships is a fundamental requirement in the study of the Earth Sciences. Traditional teaching methods have strongly relied on the 2D representations through maps and profiles that are occasionally augmented by physical models. Although most Earth Scientists have been trained to understand the 3D structure from such representations, the extrapolation requires spatial thinking skills that are difficult to learn and often form a stumbling block for students at the introductory level. The GeoWall mission is to develop Earth Science curriculum that is supported by low cost, classroom based virtual reality visualization devices.
