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.
