Working in 3D using digital elevation models

This example uses ArcScene software not normally used in schools as it is an extension to the ArcGIS package. The example investigates ice elevation and bed elevation data in Antarctica. The data used is Raster data, the cells have attributes, in this case a height value, and information about where they are in the world.

The PowerPoint can be used to demonstrate software not normally available in schools and to investigate the underlying relief of Antarctica.
