Description
The Alaska Division of Geological & Geophysical Surveys (DGGS) collected low-altitude aerial images from an unmanned aerial vehicle (UAV) on August 28, 2019, and used Structure-from-Motion (SfM) photogrammetry to produce a digital surface model (DSM) and orthoimagery of Golovin. The orthoimage and elevation data were collected to assess coastal hazards and changes. We used Trimble Business Center to process the Global Navigation Satellite System (GNSS) data used for positional control. We used Agisoft Metashape to process photogrammetry data. These products are released as a Raw Data File with an open end-user license. These products are released as a Raw Data File with an open end-user license.
