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.
What is amazing to me as an archaeologist is that the more and more I study, I realize we are resilient, we are creative, we are brilliant, and this is what makes us human, and that hasn't changed since we've been human.
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.
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.
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.
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.
