The topographical features are exaggerated and/or the city lights are intensified. Most of them are NASA images that have been enhanced or /\exaggerated/\ for contrast. The images are real data but the highs are just a bit higher than in reality. My favorite is the North West South America that shows the Andes rimming the Amazon. I also really like the Southern South America one for how the Andes is depicted. I find South America interesting geologically.Some cool topographic maps. In regardless to this particular pics, what does "exaggerated" mean in this case? I'm guessing that it means that colors & highlights were manipulated to highlight the differences?
That's one heck of a long drive! How many hours does that take you?I find this pretty interesting. You can mouse over your route and it places a marker on the graph. Whenever I do a long road trip, it always feels like I'm going uphill. Until I saw this, I thought it was a gradual climb. That's one hellava roller coaster ride.
