This amazing sandbox uses 3D visualization applications and a hands-on exhibit using a real sandbox, to create virtual topography and water. The resulting (AR) sandbox allows users to create topography models by shaping real sand, which is then augmented in real time by an elevation color map, topographic contour lines, and simulated water and lava. The system teaches geographic, geologic, and hydro-logic concepts such as how to read a topography map, the meaning of contour lines, watersheds, catchment areas, levees, and much more. It can be used to teach history and explain complex geopolitical concepts as well as use for special needs children.
