Itjtawy was ancient Egypt's capital for over four hundred years, at a period of time called the Middle Kingdom about four thousand years ago. The site is located in the Faiyum of Egypt, and the site is really important because in the Middle Kingdom there was this great renaissance for ancient Egyptian art, architecture and religion.
You think looting is bad in Egypt, look at Peru, India, China. I've been told in China there are over a quarter-million archaeological sites, and most have been looted. This is a global problem of massive proportions, and we don't know the scale.
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.
Looting has an immense impact on our ability to understand our global cultural heritage; once these objects are gone, so too is our chance of piecing together humanity's shared story.
It's absolutely critical, you know, to train young men and women not just to find sites, but also to protect sites, especially in the wake of the Arab Spring. There's been significant site-looting in Egypt and elsewhere across the Middle East.
Scientists use satellites to track weather, map ice sheet melting, detect diseases, show ecosystem change... the list goes on and on. I think nearly every scientific field benefits or could benefit from satellite imagery analysis.
If you really want to be a good archaeologist, you have to understand ancient DNA; you have to understand chemical analysis to figure out the composition of ancient pots. You have to be able to study human remains. You need to be able to do computer processing and, in some cases, computer programming.
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.
Less than 1 percent of ancient Egypt has been discovered and excavated. 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?
Archaeologists gave the military the idea to use aerial photographs for spying and field survey. We are fortunate that the spatial and spectral resolutions of the imagery available to us are so broadly useful for archaeology.
We have so many issues with overpopulation and urbanization and site looting. And this isn't just Egypt. This is everywhere in the world, even in America. So we only have a limited amount of time left before many archaeological sites all over the world are destroyed.
'Satellite archaeology' refers to the use of NASA and commercial high resolution satellite datasets to map and discover past structures, cities, and geological features.
There's even an aircraft sensor system that sends down hundreds of thousands of pulses of light measured at different return rates. It allows you to literally strip away vegetation and see entire cities beneath the rain forest canopy. This is the unbelievable future of archaeology.
When I was a child growing up in Maine, one of my favorite things to do was to look for sand dollars on the seashores of Maine, because my parents told me it would bring me luck. But you know, these shells, they're hard to find. They're covered in sand. They're difficult to see.
I give my grandfather, Dr Harold Young, a forestry Professor at the University of Maine, full credit for my career path. He pioneered the use of aerial photography in forestry in the 1950s, and we think he worked as a spy for the CIA during the Cold War, mapping Russian installations.
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.
We're using satellites to help map and model cultural features that could never be seen on the ground because they're obscured by modernization, forests, or soil.
