The area I selected to run my digital elevation model (DEM) analysis was located in an area near Bakersfield, CA. The rectangle frame I used has these coordinates: 35.0403 degrees for the top edge, 34.7350 degrees for the bottom edge, -119.0117 for the left edge, and -118.5572 for the right edge. The map is created referencing the North American Datum of 1984.
From analyzing the map, I realized there are a lot of steep slope changes occurring in many different directions. Also, being able to create a digital image of the landscape, the area selected does not have that much variance in elevation. To create the 3-Dimensional model, I had to make the Z-unit size very small in order to see a good presentation of the elevation.
I did find it very useful to see all the different gradients that are used to display and analyze land elevation. Here are a few maps I map of the area I selected:
