Service Description: Imagery Acquisition:The imagery was collected using a DJI Mavic 2 Pro UAS, operating at 300’ above ground level, along one single flight line following the center line of Middle River between 1 mile downstream of Howard road and Tract Blvd. The field collection was controlled by a DJI Smart Controller running the DJI Pilot app.Software Processing: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.Adjustment summary from ArcGIS Pro:Number of Adjusted Images843Number of Tie Points6417368Number of Solution Points2154953Mean Reprojection Error (pixel)0.21Ground Resolution (m/pixel)0.022Adjustment TypeFrameGround Control Points Involved in AdjustmentNoDWR makes no warranties or guarantees —either expressed or implied as to the completeness, accuracy, or correctness of the data.DWR neither accepts nor assumes liability arising from or for any incorrect, incomplete, or misleading subject data.This Image Service was published on 11/9/2020, by Gregory Twist of the DWR Division of Engineering, who may be contacted at 916-653-2700, or at gregory.twist@water.ca.gov.
