DIGITAL ELEVATION MODELS IN ArcGIS
Yosemite National Park

   
        The area I selected for my digital elevation model was Yosemite National Park, which is the largest habitat block set aside in the Sierra Nevada. I chose it because I have been making plans to visit it in the summer and so I wanted to create something that was of real interest to me. It covers 761,268 acres and over 3.7 million people visit every year. It has an elevation range of 500 to 4000 meters and so allows for various vegetation zones which houses great biological diversity. Its an inspiring place filled with waterfalls, deep valleys and mountains, which are showcased in the digital elevation models that I have created. Above is a ground level view from one of Yosemite's many valleys.
