    Photogrammetry-derived orthoimagery and elevation data for Barry Arm landslide, Southcentral Alaska, June 27, 2020

    Metadata Updated: July 5, 2023

    The State of Alaska Division of Geological & Geophysical Surveys (DGGS) used Structure-from-Motion (SfM) photogrammetry from an unmanned aerial system (UAS) to produce a digital surface model (DSM) and orthoimagery of a large landslide in northern Barry Arm, northwest Prince William Sound, Alaska, during near snow-free ground conditions on June 27, 2020. The survey aims to provide snow-free surface elevations and imagery data to assess landslide movement with repeat surveys during snow-free surface conditions. This data release is one of a series of DGGS publications to present elevation data. The photogrammetry and Global Navigation Satellite System (GNSS) data were collected on June 26-27, 2020, and processed using Agisoft Metashape. This data collection is being released as a Raw Data File with an open end-user license. All files can be downloaded free of charge from the Alaska Division of Geological & Geophysical Surveys website (http://doi.org/10.14509/30596).
