Purpose:
Primary purpose is to document connectivity of the back-water channels in the channel.
Survey Date and Time:
Data was collected on 6/6/2023 0700 PDT-6/7/2023 1500 PDT
Imagery Acquisition:
The imagery was collected using a DJI Phantom 4 RTK UAS, operating at 100 m above ground level, covering the entire floodplain area from San Joaquin River to Old River, using a crossing survey flight track. The field collection was controlled by the RTK controller using the DJI GS RTK App.
Software Processing:
Images were imported into ArcGIS Pro 3.1.0 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 Images 3755
Number of Tie Points 12387897
Number of Solution Points 4554825
Mean Reprojection Error / Sigma Naught (pixel) 0.27 / 0.41
Ground Resolution (m/pixel) 0.029
