Photogrammetry-derived orthoimagery and elevation data for Tununak, Alaska, collected September 13, 2022
Description
Photogrammetry-derived orthoimagery and elevation data for Tununak, Alaska, collected September 13, 2022, Raw Data File 2024-25, provides low-altitude aerial images from an unmanned aerial vehicle (UAV) in the community of Tununak, Alaska, on September 13, 2022. We used Structure-from-Motion (SfM) photogrammetry to produce a digital surface model (DSM) and orthoimagery. The orthoimage and elevation data are useful for assessing coastal and riverine hazards and changes over time.
