Service Description: UAS Imagery (1.0 inch) for Winter Island flown and processed by CDFW UAS pilot and GIS specialist Will Patterson under FAA Part 107 with a DJI Phantom 4 Pro drone using the iOS Map Pilot app (75/75 overlap) at ~351 ft altitude on November 18, 2019. Drone visual observer assistance was provided by CDFW's Aicha Ougzin. Orthomosaic processing was done with Esri Drone2Map 2.0.2, first processing 4 main areas (A,B,C,D) separately and then reprocessing small sub-areas (A1,BC1,C1,D1), then combining all areas in a single ArcGIS mosaic dataset, and exporting it at source resolution to a single final orthomosaic. No geodetic control was used other than on-board drone GPS/GNSS. Overall horizontal accuracy is unknown, but Drone2Map/Pix4D processing reports are available separately for each area. Permission to fly over the island was granted by CA Dept of Water Resources (DWR) for the parcels it owns, and privately-owned parcels were not flown over and excluded from the final orthomosaic.
