Ground control points collected during unmanned aerial systems (UAS) flights: Potomac River in White's Ferry, Maryland on October 23, 2019

Low-altitude digital images were taken over an area of the Potomac River in White's Ferry, Maryland using 3DR Solo unmanned aircraft systems (UAS) on October 23, 2019. The imagery was collected for the purpose of evaluating UAS assessment of river habitat data such as water depth, substrate type, and water clarity. Some photographs contain black and white targets used as ground control points (GCPs), which were surveyed by a field crew with a high-precision (GNSS) Global Navigation Satellite System and/or containing internal post processing kinematic (PPK) GPS system. This data release contains the csv files containing the latitude and longitude coordinates, in Universal Transverse Mercator Zone 18N referenced to the North American Datum of 1983 (2011), of the ground control points.
