Archaeologists have used aerial photographs to map archaeological sites since the 1920s, while the use of infrared photography started in the 1960s, and satellite imagery was first used in the 1970s. Sarah Parcak 1920s1960s1970s Change image and share on social
Scorpions like holes. We had to put our arms in the holes to dig out the smelting residues. We always performed critter checks before an excavation, but one morning, I put an arm in and felt a sharp pierce. When I brought my hand out, it was red and already swelling.

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
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. Sarah Parcak ancientarchaeologistexcit 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
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
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. Sarah Parcak ancientglobehundred Change image and share on social
We're literally just beginning to learn how to use satellites to find sites. More and more people are realizing there's this incredible tool. Sarah Parcak beginfindincredible 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.

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. Sarah Parcak analysisbenefitchange share on social
