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
The looters are using Google Earth, too. They're coming in with metal detectors and geophysical equipment. Some ask me to confirm sites. Sarah Parcak comeconfirmdetector Change image and share on social
I've found numerous things - settlements, temples, possible pyramids, forts, roads - the list goes on and on. I'm not as interested in the discoveries as the types of questions they help us formulate. Sarah Parcak discoveryfindformulate Change image and 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
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.

If you find a series of linear shapes in the same alignment as known archaeological features, and they match excavated examples, you still need to excavate to confirm, but you can be fairly sure that the imagery is accurate. Sarah Parcak accuratealignmentarchaeological share on social
It's an important tool to focus where we're excavating. It gives us a much bigger perspective on archaeological sites. We have to think bigger, and that's what the satellites allow us to do. Sarah Parcak archaeologicalbigexcavate Change image and share on social
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. Sarah Parcak backentirefact share on social
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. Sarah Parcak ancientfindfraction share on social
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
