Spy satellite imagery is revealing lost Silk Road outposts and the traces of vanished empires in the forbidding desert regions of Afghanistan, new research reveals.

The new archaeological insights come from decades of imagery collected by commercial and spy satellites and drones, Science reported. Among the finds: huge caravanserai, or outposts used by Silk Road travelers for millennia, and subterranean canals that were buried by the desert sands.

The archaeological sites are too dangerous to explore in person, so the new mapping effort, which is funded by a $2 million grant from the U.S. State Department, enables researchers to study Afghanistan's archaeological heritage safely, experts said in November at a meeting of the American Schools of Oriental Research in Washington, D.C.

"I'd expect tens of thousands of archaeological sites to be discovered. Only when these sites are recorded can they be studied and protected," David Thomas, an archaeologist at La Trobe University in Melbourne, Australia, who has done remote sensing work in Afghanistan but is not a member of the mapping team, told Science.

I didn't read the whole article but ti looks like they might have been using LIDAR (a laser imaging system), it's really amazing what you can learn from that sort of remote sensing.
