Sarah Parcak: Archaeology from space (script)
Summary
In the near future, you can probably find Itjtawy which was ancient Egypt's capital over four thousand years ago by using satellite data. It's not enough to see and find it with your naked eyes. Using NASA topography, it can map very subtle landscape where there was  the Nile river. It showed a very slight raised area there and the work that is coring was done. And then, there was a layer of human occupation that was a dense layer of pottery including carnelian, quartz and agate. This possible location of Itjtawy, because those stones were the most common jewelry at that time. This is the wonderful study of archaeology which is able to find and share you something over four thousand years ago.
