Mark Willis used the MikroKopter Hexakopter as a tool for aerial mapping and photogrammetry of archaeological sites.
"In short, we placed Ground Control Points (GCPs) around a man-made ponding area at roughly ten meter intervals (40 x 30 m in total area). The GCPs were shot in with a deferentially-corrected GPS (0.1 m horizontal and 0.2m vertical resolution) and with a Total Data Station (0.03m vertical and horizontal resolution). We then flew the Hexakopter at 40m above the ground surface in an east-west grid pattern with a photograph being taken straight down every 10 m or so. The camera used was an off the self Canon A540."
