Lab 6 (Week 7)

The maps/graphics found below consist of a DEM based shaded relief model, slope map, aspect map, and 3D image:

All the maps and graphics make use of the GCS NAD 1983 as their reference geographical coordinate system. The location presented spans left to right from -119.23 decimal degrees to -119.17 decimal degrees. From bottom to top, the map spans from 34.27 to 34.34 decimal degrees. A decimal degree corresponds to roughly 100 km in this region. Originally, I was going to us Lake Tahoe, California as the study location. Due to the high internet traffic at the USGS website, I was unable to download the aforementioned location. As a result, the TA provided this specific location, which corresponds to the mountain range north of Oxnard and Ventura. Ventura Country lies right smack between several mountain ranges and is bordered on its west coast by the Pacific Ocean. These mountains (pictured) are part of the Transverse Mountain Ranges of Southern California. Specifically, the mountain range directly north of Ventura and Oxnard is known as the Topatopa Mountains. This range approaches elevations of nearly 7,000 feet at its peak.
