When a wall is slowly covered over by earth, the materials it's made from decay and become part of the soils around and above it, sometimes causing vegetation above and next to the wall to grow faster or slower. Satellite imagery helps archaeologists to pick up these subtle changes.

There are so many previously unknown sites and structures all over the world. And I think most importantly what satellites help to show us is we've actually only found a fraction of a percent of ancient settlements and sites all over the world.

In Egypt, I do survey work on the ground. That's really the most important part of using satellite images. You know, it helps us to find potential locations for sites, and then we get to go there on the ground and confirm what we've seen.
