DEM


A DEM map, also known as a Digital Elevation Model, is a digital file consisting of terrain elevations for ground positions at regularly-spaced horizontal intervals (google define). The above map is a great model or example for a DEM map. It summarizes the date found at the Hartnett study site, and the color/shading of the different levels of elevation makes the map alot easier to read and easier to distinguish (the different layers).
