Week 7: Digital Elevation Models

BY DAVID PHILLIPS

The area I selected is quite mountainous. I constructed a series of DEM's. A DEM is a Digital Elevation Model. DEMs contain a huge amount of information about the elevation (and other aspects) of the terrain portrayed on the map. The DEM here is a small range of mountains near the coast of California. A hillshade model (first in the sequence below) delineates the sort of terrain by using light and dark shades of grey. The color overlay enables the viewer to see that the terrain rises as you travel west to east. A slope model describes the type of slopes in the DEM.

EXTENT OF THE MAP:

39.8291666661 North to 39.3838888883 North
105.788888889 West to 104.969444445
