Photogrammetry-derived historical orthoimagery for Homer, Alaska from 1951, 1952, 1964, and 1985

The State of Alaska Division of Geological & Geophysical Surveys (DGGS) used Structure-from-Motion (SfM) photogrammetry to produce orthoimagery for the City of Homer and surrounding areas from 1951, 1952, 1964, and 1985 imagery. The orthometrically corrected imagery are for assessing coastal hazards and changes. The original photographs were collected by the U.S. Air Force (1951 and 1952), the Bureau of Land Management (BLM; 1964), and the National Aeronautics and Space Administration (NASA; 1985). Data were processed using Agisoft Metashape software. 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/10.14509/30824).
