- Place your hands in the sand and move it around.
- Create different formations, such as mountains and valleys.
- Observe how and where the virtual water flows.Note the water’s direction, speed and height.
Sensors detect if you made a hill or scooped a canyon. A computer and projector overlays elevation and moving water. Superimposing computer-generated images into our real world is called augmented reality.
Topography is the study of the Earth’s surface – high and low elevations. It helps us understand the land’s mountains and valleys, water flow into flood plains, river deltas and watersheds, and changes over time.
