Lab 6: DEMs in ArcGIS

Hillshade Layer

Slope Layer

Aspect Layer

DEM Arc Scene (3D)

       For this week's lab, we created D.E.M.s (Digital Elevation Models) using the DEM data from the class website. The extent for this data is 39.8292 decimal degrees for the top, -105.7889 decimal degrees for the left, -104.9694 decimal degrees for the right and 39.3839 decimal degrees for the bottom. The coordinate system used was the North American Global Coordinate System from 1983. The hillshade layer shows the relief and terrain in this area. The slope layer shows the degree and intensity of the angle of the slope in this region. The aspect layer shows the directionality of the terrain. The DEM shows all the data in a three-dimensional model.
