Cashman, M.J., Brosnahan, S.M., Caldwell, S.H., Staub, L.E., DeWitt, J., Young, J., Duda, J., and Griese, A.J., 2020, Low-altitude aerial imagery from unmanned aerial systems (UAS) at select locations over the Potomac River, October 2019: U.S. Geological Survey data release, https://doi.org/10.5066/P970EQ7D.

These images from an Unmanned Aerial System (UAS) were collected to establish capabilities and limitations for using new technology for mapping and measuring riverine environments. This was one component of methodological comparison field campaign conducted in conjunction with a topobathymetric lidar collection of the Potomac River Corridor in late 2019. Imagery were collected for the purpose of evaluating UAS assessment of river habitat data such as water depth, substrate type, and water clarity. Color images were collected with resolution and overlap for photogrammetry and creation of digital elevation models and orthomosaics. Comparisons will be made to other data derived from topobathymetric lidar and more established technologies such as real-time-kinematic (RTK) GPS, acoustic doppler current profilers (ADCP), and multi-beam echo sounders.
