Photogrammetrically-derived Digital Elevation Models (DEMs) in the Puyallup River headwaters, 1991-92
Over the second half of the 20th century, the U.S. Geological Survey collected aerial imagery over many glaciers in western North America. Those images were later scanned and archived as digital images (Nolan and others, 2017; https://doi.org/10.18739/A2VH5CJ8K). Imagery over Mount Rainier often extended down-valley enough to capture the majority of the proglacial watershed below a given glacier. Imagery from 1991 and 1992 was used to derived digital elevation models (DEMs) of all the major glacial headwater basins in the Puyallup River watershed using structure-from-motion (SfM) photogrammetry (Fonstad and others, 2013). The resulting elevation datasets were further used to assess geomorphic change in those headwaters.
Processing methods follow exactly from Anderson and Shean (2021; https://doi.org/10.1002/esp.5274). DEM-specific details are provided in metadata and in an auto-generated report from the processing software (Agisoft Metashape), both of which are packaged in a zip folder along with the DEM itself.
