Ground control point locations for Uncrewed Aircraft System (UAS) surveys at dryland sites 40 km south of Moab, Utah in May 2023

In support of U.S. Geological Survey (USGS) Southwest Biological Science Center researchers, and in coordination with the Bureau of Land Management (BLM) and National Ecological Observatory Network (NEON), the USGS National Uncrewed Systems Office (NUSO) conducted uncrewed aircraft systems (UAS) remote sensing flights over two BLM Assessment, Inventory, and Monitoring (AIM) plots at the NEON Moab site in Utah for multi-scale carbon sequestration research on public lands. The UAS data collected include natural color, multispectral, and hyperspectral imagery, and lidar to capture diverse information about vegetation and soils on drylands. The first site (“site 1”) features intact sagebrush and was mapped on May 3, 2023. The second site (“site 7”) is located on a grazed rangeland environment and was mapped on May 5, 2023. These UAS surveys were conducted in early May 2023 to coincide spatially and temporally with ground-based BLM AIM sampling and airplane-based remote sensing surveys by NEON. This portion of the data release presents ground control point (GCP) location data collected during low-altitude UAS surveys at two dryland sites approximately 40 km south of Moab, Utah. Survey control was established using Propeller AeroPoint temporary GCPs distributed throughout the survey area. GCPs were post-processed with corrections from a concurrently operating Trimble R8s post-processed kinematic (PPK) GNSS base station. Six GCPs were used at each survey site for a total of twelve GCPs described in this data release.
