DEMs in ArcGis

The area I selected is in the Sierra Nevada mountains in eastern California, near Highway 395. The boundaries of this map are 35.86 degrees north to 36.46 degrees north and 117.62 degrees west to 116.75 degrees west. Visible in this particular map are several mountain ranges spanning from north to south with valleys between them. The scale of this map is 1:399,008.

This map shows a shaded relief of the area.


This map shows the varying slopes of the area defined by different colors. Green signifies a flat slope, while dark red signifies the most extreme slope.


This map shows the aspect, which is the direction the land faces. Gray is flat, red is north, yellow is east, turquoise is south, and blue is west.


The following three maps show 3-dimensional views of the area from different angles.
