Town Brook Annotated Orthomosaic (Plymouth, MA)

Annotated orthomosaic of Town Brook in Plymouth, MA where the Off Billington Dam was removed. Imagery was collected with a DJI Phantom 3 Professional sUAS flown at 65 ft above ground level. Overlapping stills from 4K video were processed in Agisoft PhotoScan Professional. Imagery collected by a certified FAA Part 107 remote pilot on Sept. 28, 2017. The reach assessed by the USACE stream tour team for the SVAP2 study is noted by the red lines.
