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.
The most exciting moment as an archaeologist happened when I was looking at the great archaeology site of Tannis, which of course we all know from 'Indiana Jones.' We got satellite imagery of the city of Tannis, we processed it, and literally from thousands of miles away from my lab in Alabama, we were able to map the entire city.
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.
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.
