Cramer, J.C., Brosnahan, S.M., Ackerman, S.D., Pendleton, E.A., Sturdivant, E.J., and Borden, J., 2021, Aerial Imagery collected during unoccupied aircraft systems (UAS) operations in Massachusetts and Maine between March 2018 - September 2018: U.S. Geological Survey data release,


Low-altitude (80 and 100 meters above ground level) digital images were collected at Sage Lot Pond in Waquoit, Massachusetts, two sites on the Mill River in Taunton, MA, Great Marsh in Barnstable, MA, the Wells National Estuarine Research Reserve in Wells, ME, and on the Woods Hole Oceanographic Institution Quissett Campus in Woods Hole, MA using 3DR Solo unoccupied aircraft systems (UAS) during 2018. These images were collected to support science and data needs in wetland research, topographic mapping, and landcover detection at the U.S. Geological Survey Woods Hole Coastal and Marine Science Center. The imagery and associated ground control points can be used to create Digital Elevation Models (DEMs), orthoimages, and reflectance [...]

The objective of obtaining these ground control points was to constrain the photogrammetric products constructed from the aerial images taken, by providing survey-quality ground validation, which far exceeds the accuracy that can be provided from the photo geolocations alone. Transect points are used to validate the final accuracy of the products, and ground control points are used to geolocate the products as accurately as possible.
