Lab 6

The area used for this lab ranges from about the Arapaho National Forest and Mt. Evans to Denver and the surrounding cities. These locations are all contained within Colorado. There is a noticeable change in elevation from the Arapaho National Forest to the cities. The elevation decreases in a left to right shift across all of the maps. The left part of each map contains the rugged and uneven terrain representative of mountains and hills. The right part of each map, where the cities are located, is considerably flatter as compared to the left part. This feature is prominently highlighted by the "3-D DEM Image," which depicts the terrain in a much more intuitive sense. The red area on the "3-D DEM  Image" is where the cities are predominantly located, whereas the blue colored area depicts the mountainous terrain. The more rapid change in elevation in the mountainous regions can be seen by the change in the shades of blue. Contrastingly, the red color is more uniform throughout the location of the cities, which is indicative of flatness. The corresponding legend gives a relative sense of the elevation that each color indicates.

The extent information of the selected area is given as: 39.829166666101° (latitude) for the top edge of the area, 39.3838888883° (latitude) for the bottom edge of the area, -105.788888889° (longitude) for the left edge of the area, and -104.969444445° (longitude) for the right edge of the area. The North American Datum of 1983 was used to present the data and the "GCS (Geographic Coordinate System) North America 1983" spatial reference was used.
