Helicopter-based videos and orthomosaic maps produced for Integrated Water Science basin riverine study sites, 2022

A Bell 407 helicopter with a gyro-stabilized gimbal was used to collect aerial videos of Integrated Water Science basin riverine study sites in 2022. Videos were collected using both natural color and thermal infrared cameras. These videos were used to determine the feasibility of estimating river surface velocity using aerial imagery. Orthomosaic maps were produced from the natural color videos using photogrammetry techniques. Separate child pages were created to provide access to both the videos collected and the orthomosaic maps produced for each IWS basin (Delaware River, Illinois River, and Upper Colorado River).
