Via Marginal Revolution, here's a piece on how archeologists are using drones in their work.
Causes me to ask: when is FSA going to drones? Last I knew FSA had a set of aerial photographs which were scaled and ortho-corrected (which I think means adjusted for changes in elevation) with which one could measure the area of a field, and a yearly set of slides taken from small planes to help identify which crop was in which field. I'm sure that's changed as they've implemented their GIS system, but I'm not sure how. On the theory the agency still needs to spot-check the accuracy of what they're being told by the farmer, I'd assume there's still some aerial slides being taken. Drones might be a better approach (except for all the rules and regulations about their use, which presumably archeologists in Peru don't need to worry about).
