Digital Elevation Models (DEMs)


3-D Model







Extent
Top: 34.5591666657748
Bottom: 34.213611110196
Left: -118.469444445439
Right: -117.842500000952

I chose an area in the Southern California region to carry out this Digital Elevation Model. I selected an area near the beginning of mountainous range so that we can see different elevations. I used Spatial Analysis methods to get most of these graphs. These Spatial Analysis features utilize raster inputs to carry out these functions. For all the maps, the geographic coordinate system used is the North American 1983 as said in the properties table of the maps.
