Low-altitude digital images were taken over an area of the Potomac River in Point of Rocks, Maryland using 3DR Solo unmanned aircraft systems (UAS) on October 24, 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.

Low-altitude (80 and 100 meters above ground level) digital images were taken over an area of the Plum Island Estuary and Parker River National Wildlife Refuge (NWR) in Massachusetts using 3DR Solo unmanned aircraft systems (UAS) on February 27, 2018. These images were collected as part of an effort to document marsh stability over time and quantify sediment movement using UAS technology. Each UAS was equipped with either a Ricoh GRII digital camera for natural color photos, used to produce digital elevation models and ortho images, or a MicaSense RedEdge multi-spectral camera that captures five specific bands of the visible spectrum (blue, green, red, red edge, and near-infrared), which can be used to classify vegetation. The MicaSense camera covered a smaller subsection of the same polygonal area of the marsh that the Ricoh imaged. Some photographs contain black and white targets used as ground control points (GCPs), which were surveyed by a field crew with a high-precision Real Time Kinematic Global Position System. This data release includes the original images from both cameras, as well as a csv file containing the latitude and longitude coordinates, in Universal Transverse Mercator Zone 19 referenced to the North American Datum of 1983, of the ground control points needed to complete any photogrammetry projects using the original photographs, and GPS transect points used to evaluate the photogrammetry products created.

Low-altitude aerial images were obtained by Elevated Media Concepts LLC from small unmanned aerial systems (UAS), over historic Ellicott City on June 18, 2018 after major flooding events. These images were collected to document and monitor effects of flooding, including property damage in Ellicott City, Maryland. Some photographs contain temporary black and white targets used as ground control points (GCP's), which were surveyed by a field crew with a high-precision Real Time Kinematic Global Position System. This data release includes a Comma Separated Values (CSV) file with the target positions in Maryland State Plane Coordinate system referenced to the North American Datum of 1983 used as ground control points.
