Service Description: Purpose: Primary purpose is to quantify floating and submerged aquatic vegetation in the channel. Survey Date and Time: Data was collected on 3/8/2023 1015-1100 PST Imagery Acquisition: The imagery was collected using a DJI Mavic 2 Pro UAS, operating at 200’ above ground level, along one single flight line following the center line of Middle River from Old River to 1 mile downstream of Howard road. The field collection was controlled by a DJI Smart Controller running the DJI Pilot app. Software Processing: Images were imported into ArcGIS Pro 2.8.0 using the Ortho Mapping workspace tool, block adjusted, and an Orthomosaic was generated. No external control points were used for this project.
