ancient exciting found fraction history percent sites time
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... It's the most exciting time in history to be an archaeologist.
across locate quickly sites
I predict that there are hundreds of thousands, if not millions, of undiscovered ancient sites across the globe. The only way to map them and locate them quickly is from satellites.
ancient found fraction help percent sites structures unknown
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.
absolutely across arab egypt elsewhere men middle protect train wake women
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.
ancient chemical computer figure good human processing study
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.
benefit benefits change detect ecosystem field goes ice imagery list map nearly satellite scientific scientists sheet track
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.
entire human pull pyramids scale temples visualize
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.
ancient architecture art capital egyptian four great hundred kingdom middle period site thousand time
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.
advanced against ancient discovered egypt less percent population protect race time
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?
bring covered difficult dollars favorite growing hard sand
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.
commercial discover high map nasa past resolution satellite
'Satellite archaeology' refers to the use of NASA and commercial high resolution satellite datasets to map and discover past structures, cities, and geological features.
aircraft beneath cities entire forest future light literally measured rain return sends strip system thousands vegetation
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.
affect beneath buried changes depending ground imagery landscapes map radar remains satellite scientists technology
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.
cultural features ground model seen using
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.
