Photogrammetry-derived orthoimagery and elevation data for Chefornak, Alaska, collected August 18, 2022
Description
Photogrammetry-derived orthoimagery and elevation data for Chefornak, Alaska, collected August 18, 2022, Raw Data File 2024-26, provides low-altitude aerial images from an unmanned aerial vehicle (UAV) in the community of Chefornak, Alaska, on August 18, 2022. We used Structure-from-Motion (SfM) photogrammetry to produce a digital surface model (DSM) and orthorectified imagery. The orthoimage and elevation data are useful for assessing riverine hazards and changes over time. This data collection is released as a Raw Data File with an open end-user license.
