This is a collection of actual landscapes. Some are National Park areas which I have visited, and others are places I have been and found interesting. These topographical maps were created using Blender with a link to NASA for terrain elevations. These topo maps are useful if you plan on hiking in these areas. The detail is better with close-up views, and could be created using this system.
