  Archaeology’s taking to the air. Researchers spent a month this summer testing a semi-autonomous unmanned aerial vehicle—basically a semi-autonomous drone—high in the Andes in Peru. The goal: to scan a colonial town from the 1500s that had been built over an Incan settlement, and then abandoned.


  It’s a collaboration 1 between Vanderbilt University archaeologist Steven Wernke and engineering professor Julie Adams. Adams tricked out a vehicle from Aurora 2 Flight Sciences to include cameras and algorithms that allow the drone to achieve optimal 3 flight patterns. The resulting detailed 4 3-D map will be much more precise than high-resolution satellite images.


  Here’s Steven Wernke: “By our calculations this vehicle will be able to take imagery of an area in about 10-15 minutes that would take two or three entire field seasons using traditional methods.”


  The system can fit into a backpack. Once the researchers incorporate what they learned, they hope the technology can assist in the rapid cataloguing of a variety of archaeological sites, some of which are already being lost to the ravages 5 of new developments and time.
