With population pressures, urbanization, and modernization encroaching, we're in a race against time. Why not use the most advanced tools we have to map, quantify, and protect our past?
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.
The only technology that can 'see' beneath the ground is radar imagery. But satellite imagery also allows scientists to map short- and long-term changes to the Earth's surface. Buried archaeological remains affect the overlying vegetation, soils and even water in different ways, depending on the landscapes you're examining.
The most exciting part of what I do is understanding the scale of what we don't know. There are just countless archaeological sites all over the world, and one of the most important and best ways of finding them is using digital technology.
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.
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.
