Lab 6 - DEMs




The area shown here is a section of the Grand Canyon, unfortunately I wasn't able to zoom in on what I originally intended, Mount St. Helens. I have never been to the Grand Canyon, even though I do not live all that far from it. These maps gave me an idea of how steep the Grand Canyon really is. The maps included here are the aspect map, shaded relief model, and the slope map.

The extent information in decimal degrees:
Top: 40.4980555551
Left: -107.858333332
Right: -107.089166666
Bottom: 39.1311111105

Datum: Datum of North American 1983

The geographic coordinate system is the GCS North American 1983
