Archaeological Surveys With Drone Mapping - Using multispectral imaging to detect ancient man-made structures

7 December 2017

For the past year and a half, Henry Webber, a Ph.D. candidate at the University of Bristol’s Department of Archaeology and Anthropology, has been gathering data using a drone that carries a MicaSense RedEdge multispectral sensor. He has flown over agricultural fields that have known archaeological features beneath them and has compared his findings with more conventional tools for surveying such as a magnetic gradiometers, which detect changes beneath the surface by measuring the strength and orientation of the magnetic field of the ground below.
