    • Unoccupied Aerial System-mounted image velocimetry and Doppler velocity radar data for computation of river velocity and discharge collected at seven locations in Colorado in 2023: Calibration Images

    Metadata Updated: November 26, 2025

    This child item contains images of each field site annotated with labeled calibration marks and associated pixel locations for each dataset. The images can calibrate image velocimetry results into real-world units (meters, for example). <br> Each Field Site is abbreviated in various files in this data release. File and folder names quickly identify which site a particular file or dataset represents. The following abbreviations are used: <ul> <li>ACS: Anthracite Creek at Somerset, Colorado, USA</li> <li>BRA: Blue River below Dillon, Colorado, USA (collected in August 2023)</li> <li>BRJ: Blue River below Dillon, Colorado, USA (collected in June 2023)</li> <li>CRG: Colorado River below Glenwood Springs, Colorado, USA</li> <li>CRR: Colorado River above Roaring Fork River at Glenwood Springs, Colorado, USA</li> <li>MCA: Maroon Creek near Aspen, Colorado, USA</li> </ul>
