'Satellite archaeology' refers to the use of NASA and commercial high resolution satellite datasets to map and discover past structures, cities, and geological features.
When a wall is slowly covered over by earth, the materials it's made from decay and become part of the soils around and above it, sometimes causing vegetation above and next to the wall to grow faster or slower. Satellite imagery helps archaeologists to pick up these subtle changes.
I think archaeologists are stuck, and we are losing our past at a very rapid rate. Tens of thousands of sites will be lost, and we've only unveiled a tiny percent of the past.
When I was a child growing up in Maine, one of my favorite things to do was to look for sand dollars on the seashores of Maine, because my parents told me it would bring me luck. But you know, these shells, they're hard to find. They're covered in sand. They're difficult to see.
I'm an Egyptologist. I'm a remote sensing specialist, and I'm a space archaeologist.
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.
