Description
Photogrammetry-derived orthoimagery and elevation data for Saint Michael, Alaska, collected July 8, 2022, Raw Data File 2024-22, provides low-altitude aerial images from an unmanned aerial vehicle (UAV) in the community of Saint Michael, Alaska, on July 8, 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 riverine hazards and changes over time. All files can be downloaded from the Alaska Division of Geological & Geophysical Surveys website (http://doi.org/10.14509/31290).
