    • GNSS elevation data collected in 2024 on beaches and areas relevant to flood hazard studies in Alaska communities

    Metadata Updated: September 17, 2025

    Elevation point data were collected in Deering, Golovin, Koyuk, Kotzebue, and Unalakleet, Alaska between June and September 2024. Coastal elevation profiles were measured at previously established locations. Other data points are categorized as base station, bathymetry, benchmark, camera calibration data, community-based monitoring profile, drainage observation, flood staff, ground control point, miscellaneous, and water level. The elevation data were collected with real-time kinematic global navigation satellite system (RTK-GNSS) equipment. Data are available in a single CSV file per community. For easting and northing coordinates, Deering, Golovin, and Kotzebue use UTM 3. Unalakleet and Koyuk use UTM 4.
