    Photogrammetric digital surface models and orthoimagery for the continuous coastline, Wales to Platinum, Alaska, segment G: Nunam Iqua to Chevak

    Metadata Updated: November 10, 2020

    Aerial photographs of the coastline from Nunam Iqua to Chevak were collected on September 1, 2015. The photographs were processed using Structure-from-Motion (SfM) photogrammetric techniques. Global Positioning System (GPS) checkpoints were collected via a Global Navigation Satellite System (GNSS) survey conducted between August 15 and September 14, 2015. For the purposes of open access to elevation and orthoimagery datasets in coastal regions of Alaska, this collection is being released as a Raw Data File with an open end-user license. This file is a single-band, 32-bit float DSM (digital surface model) which represents surface elevations of buildings, vegetation, and uncovered ground surfaces in meters with 20 cm GSD. The No Data value is set to -32767. The file employs LZW compression.
