I already find pyramids from space. Is there anything cooler than that?

I can't tell you the number of times I've been walking over an archaeological site. And you can't see anything on the ground, and pull back hundreds of miles in space, and all of a sudden you can see streets and roads and houses and even pyramids.

When you think about the scale of human populations all over the world and the fact that there's so much here, really, the only way to be able to visualize that is to pull back in space... It allows us to see hidden temples and tombs and pyramids and even entire settlements.

I've found numerous things - settlements, temples, possible pyramids, forts, roads - the list goes on and on. I'm not as interested in the discoveries as the types of questions they help us formulate.

Google Earth is an incredible resource because from hundreds of miles in space, we can zoom in, and we can find things. Everyone always looks for their house first. That is the tip of the iceberg with remote sensing.

You just pull back for hundreds of miles using the satellite imagery, and all of a sudden this invisible world become visible. You're actually able to see settlements and tombs - and even things like buried pyramids - that you might not otherwise be able to see.
