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.
In Egypt, I do survey work on the ground. That's really the most important part of using satellite images. You know, it helps us to find potential locations for sites, and then we get to go there on the ground and confirm what we've seen.
Before doing fieldwork in Middle Egypt, I analyzed satellite imagery to determine exactly where I wanted to go. Within three weeks, I found about 70 sites. If I had approached this as a traditional foot survey, it would have taken me three and a half years.
