Drone Imagery of the Little Truckee river collected on 10/06/2020.

The imagery was collected using a DJI Mavic 2 Pro UAS, operating at 80m (262ft) above ground level. Photos were taken along a 60-degree course angle, with 65% side overlap and 85% front overlap. The field collection was controlled by a DJI Smart Controller running the DJI Pilot app.

Images were imported into ArcGIS Pro 2.6 using the Ortho Mapping workspace tool, block adjusted, and an Orthomosaic was generated. No external control points were used for this project.
