Description
Photogrammetry-derived orthoimagery and elevation data for Kivalina, Alaska, collected June 7, 2922, Raw Data File 2022-12, uses low-altitude aerial images, collected from an unmanned aerial vehicle (UAV) on June 7, 2022, and Structure-from-Motion (SfM) photogrammetry to produce a digital surface model (DSM) and orthoimagery for the community of Kivalina, Alaska. The orthoimage and elevation data are for assessing coastal hazards and changes. We used Trimble Business Center to process the Global Navigation Satellite System (GNSS) data used for positional control and NOAA VDatum to adjust elevation data. We used Agisoft Metashape to process photogrammetry data. These products are released as a Raw Data File with an open end-user license. All files can be downloaded from the Alaska Division of Geological & Geophysical Surveys website (http://doi.org/10.14509/30902).
