Otter Creek pre-restoration orthomosaic and elevation products for the Maumee Area of Concern, Toledo, Ohio, September 2020

The orthomosaic, digital surface model and point cloud presented here document conditions at Otter Creek in Toledo, Ohio in September 2020, prior to planned ecological restoration. The study site is part of the Maumee Area of Concern being restored as part of the Great Lakes Restoration Initiative. Aerial images were collected using a DJI Phantom with FC6310 sensor at an elevation of approximately 70 meters above the study site. Data were processed using structure-from-motion techniques to generate a point cloud (.las), digital surface model (DSM; .tif) and an orthomosaic (.tif) for the site. Products provide baseline information about terrestrial and emergent wetland communities and riparian areas against which to compare changes following restoration. Control points used to georeference the products are provided as a .csv file, along with a processing report generated by the structure-from-motion processing software.
