    • UAS imagery and related products collected for structure-from-motion work obtained by using uncrewed aerial systems from an erosion prone area north of Medina River Natural Area near San Antonio, Texas, August 14, 2019, and July 8, 2022

    Metadata Updated: January 21, 2026

    Uncrewed aerial system (UAS) flights were conducted by the U.S. Geological Survey at an edge-of-field site located north of Medina River Natural Area near San Antonio, Texas on August 14, 2019, and July 8, 2022, to support efforts aimed at estimating edge-of-field erosion and potential sediment loading into the Medina River near San Antonio. Data provided here include imagery obtained during the flights, and ground control point (GCP) information. Additional products including automatically generated point clouds, digital surface models (DSMs), and orthomosaic imagery produced using structure-from-motion (SfM) techniques are part of this data release.
