Dudes also I'm struggling on changing the elevation view on google earth. Ive done it before but now I'm tarded
Do you mean you want to see the 3D lay of the land, or some sort of topos?
To get a 3D view, just move the arrows around the eye in the top right. If the eye isn't there, on the menu bar at the top click:
View > Show Navigation > Always
It should be visible and there to use then.
Hope this helps you out.
