A new custom software application is allowing archeologists to use satellite imagery to survey massive areas for signs of ancient human habitation. It's really quite surprising how much can be seen from space, and how little of it has been explored. Unfortunately the most promising sites seem to all be in Syria, which as we all know is not the most welcoming of places to do science at the moment. It's hoped that the improving situation in Iraq will allow further testing of this technology in that region.
