Service Description: Purpose: The Primary purpose of this UAV mission is to delineate the remaining wetted channel following the high water (flood) events of Spring 2023. The Phantom 4-RTK was used for this specific mission plus additional ground control in order to create a high-quality DEM to reflect the post-flood existing ground surface within the Paradise Cut flood plain (Levee to Levee) and develop subsequent products (contours, orthophotos, etc.). Survey Date and Time: Data was collected on 8/9/2023 1015-1230 PST Imagery Acquisition: The imagery was collected using a Phantom 4 PRO RTK, operating at 250’ above ground level, multiple flight lines criss-crossing the center line of Paradise Cut from the weir on the San Joaquin River to the confluence with Old River. The field collection was controlled by a DJI Smart Controller running the DJI Pilot app. Software Processing: Images were imported into AgiSoft using GCP’s the precise RTK-GPS values, block adjusted, and an Orthomosaic was generated.
