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. All files can be downloaded from the Alaska Division of Geological & Geophysical Surveys website (http://doi.org/10.14509/31293).
