Digital elevation models of the coast of Alaska from Icy Cape to Cape Prince of Wales, 2016

Metadata Updated: July 6, 2024

This part of the data release presents digital elevation models (DEMs) spanning the ocean shoreline of Alaska from Icy Cape to Cape Prince of Wales. Aerial images were collected, and data were processed, by Fairbanks Fodar (https://www.fairbanksfodar.com) in Fairbanks, Alaska, for the U.S. Geological Survey. The aerial images, from which the DEMs were created, were collected in 2016 between August 29 and September 4 and extend from the shoreline to 400-4000 meters inland. The aerial images were collected with precise Global Positioning System (GPS) navigation data from a manned aircraft and were then processed into DEMs photogrammetrically using structure-from-motion (SFM) processing methods as described in Nolan and others, 2015. The included files contain single-band, 32-bit, floating point raster data and are available in GeoTIFF format with 20 cm cell size. The DEM rasters were converted to cloud optimized GeoTIFF format by USGS researchers. Due to file size and number limitations, the DEMs have been divided into three groups by geographic location. Users are encouraged to use the Tile Index shapefile, which is also available in this data release, to identify elevation data files that are appropriate to a specific area of interest.
