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.

Satellite datasets like WorldView can see objects as small as 1.5 feet in diameter. In 2014, WorldView-3 will be able to see objects a small as a foot. Sarah Parcak datasetdiameterfoot Change image and share on social
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.

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? Sarah Parcak advanceencroachmap Change image and share on social
We want to excite the world about what's out there. But we don't want them to say, 'Oh, there are lots of sites in Egypt - let's loot.' Sarah Parcak egyptexciteloot Change image and share on social
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. Sarah Parcak abilitychancecultural Change image and share on social
We've found that patterns of site looting have increased between 500 and 1000 percent since the start of the Arab Spring. Now this is a problem as old as human beings. People were looting tombs 5,000 years ago in Egypt as soon as people were buried, but the problem is only getting worse and worse. Sarah Parcak 000agoarab share on social
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. Sarah Parcak earthfindgoogle share on social
What these satellites do is they record light radiation that's reflected off the surface of the Earth in different parts of the light spectrum. We use false color imaging to try to tease out these very subtle differences on the ground. Sarah Parcak colordifferenceearth share on social
WorldView-3 goes into the mid-infrared wavelength, allowing you to see very subtle geological differences on the sites at a 0.4-metre resolution. Sarah Parcak allowdifferencegeological Change image and share on social
