Lab #6 DEM

I chose to acquire a DEM from a region of the Yosemite National Park. I had a difficult time finding this region from just looking at the map on the website, however there was a tab which added the counties to the map and I was able to find the park. The process of downloading the map was very practical and easy to do.
The different overlays which I projected the map in were hillshade, slope, and aspect. The DEM layer was set above these other layers in the ArcMap table of contents in order to see the information portrayed on the DEM layer. I picked different color schemes to best suit the information displayed.
Finally there was a 3D map to be made. The DEM had to be in ArcScene in order for this 3D map to be made. When recently inputting the information into ArcScene, I could not find my 3D image, the screen was blank. The problem was solved by adjusting the value for the "Z unit conversion factor" to a .0001 value.
There were more toolbars to be used for this DEM lab which allowed the viewing of the DEM in multiple ways. It was necessary to keep track of which toolbars to use and when to use them. This lab was interesting, especially when working with a 3D visual in ArcScene.
