Summary
These field data such as first floor elevation and bathymetric surveys were collected to support development of coastal mapping products and advance storm response and recovery in Alaskan coastal communities. The data consists of essential community infrastructure elevation data to better understand flood exposure and support analysis of flood mitigation solutions, bathymetric surveys to improve bathymetric maps, and measurements for testing and developing models and improving understanding of oceanographic processes in western Alaska. This product may be of use by scientists, emergency responders, managers, planners, and residents of western coastal Alaska.

First finished floor elevation data collected in seven Alaska communities, geographic coordinate system
First finished floor elevation data, as well as ground survey points for critical infrastructure, for example bridges, fuel farms, and power generators, were collected in Elim, Golovin, Kotzebue, Mekoryuk, Saint George, Stebbins, and Tununak, Alaska. The elevation data were collected with real-time kinematic global navigation satellite system (RTK-GNSS) equipment. Data are available in CSV file format. Two files are available per community: one in a geographic coordinate system (this dataset) and the other in the Alaska State Plane coordinate system (in this same data release). Additionally, the supplemental survey reports are provided.

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