Otter Creek pre-restoration orthomosaic and elevation products, Toledo, Ohio, September 2022

The orthomosaic, digital surface model and point cloud presented here document conditions at Otter Creek in Toledo, Ohio in September 2022, prior to planned ecological restoration. Images were collected using a 3D Robotics Solo aircraft with GNSS GPS upgrade, Mission Planner software, and a Pentax Ricoh GRII 3-band digital camera sensor. Imagery acquisition flights were approximately 400 feet above the surface of the lake water. 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. Ground 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.
