Photogrammetry-derived orthoimagery and elevation data for Kongiganak, Alaska, collected June 7, 2023
Description
Photogrammetry-derived orthoimagery and elevation data for Kongiganak, Alaska, collected June 7, 2023, Raw Data File 2024-20, provides low-altitude aerial images from an unmanned aerial vehicle (UAV) in the community of Kongiganak, Alaska, on June 7, 2023. We used Structure-from-Motion (SfM) photogrammetry to produce two digital surface models (DSM) and two orthorectified images. The populated areas of Kongiganak were the focus of the primary aerial survey, while the secondary aerial survey covered the landfill to the northwest of the community. The orthoimage and elevation data are useful for assessing riverine hazards and changes over time.
