Drone Photographs from the Beaver Dam Area 2020-7-24 Flight Date (Dover, NH, USA)

These are the raw drone aerial images taken of the beaver dam area on July 24, 2020 for the Evans et al. Sawyer Mill dam removal study. Alexandra Evans, a certified FAA Part 107 remote pilot, served as the remote pilot in command for the flight mission and was accompanied by spotters.<br>A DJI Phantom 3 Professional drone was used to take the images, equipped with its original RGB camera and a polarizing filter. Please see the referenced automated flight paths for details on altitude, image overlap, etc. The flight paths were executed using the Litchi flight app.<br>These materials were made using resources from an NSF EPSCoR funded project “RII Track-2 FEC: Strengthening the scientific basis for decision-making about dams: Multi-scale, coupled-systems research on ecological, social, and economic trade-offs” (a.k.a. "Future of Dams"). Support for this project is provided by the National Science Foundation’s Research Infrastructure Improvement NSF #IIA-1539071.
