In August 2023, the USGS National Uncrewed Systems Office (NUSO) participated in a collaborative field campaign to collect remote sensing data over agricultural crop fields in California's Central Valley. Hyperspectral satellites were commissioned in coordination with hyperspectral UAS flights at an altitude of 300 feet above ground level.
