Orthomosaic map produced for the Illinois River Integrated Science basin, Illinois River near Starved Rock study sites, June 7, 2022
Description
A Bell 407 helicopter with a gyro-stabilized gimbal was used to collect aerial videos of Illinois River Water Science Basin (IWS) 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. Photogrammetry techniques were used with the natural color video images to produce an orthomosaic map of the study reach.
