Sierra Nevada DEM


     The area of interest is the southern portion of the Sierra Nevada, between the southern portion of San Joaquin Valley and Owen's Valley.  The Sierra Nevada is a distinguishable feature that is unique to the California's landscape. This area is perfect to show the usage and applications of DEMs in ArcGIS.   From the 3D model perspective the area looks very hard to maneuver by vehicle; therefore, DEM and ArcGIS allows the observer to scope the area using this tool.  In addition, other assets (Slope Model, Aspect Model, Shaded Relief Model) of the tool allows ArcGIS users to get overall picture of the terrain.
