• Digital shorelines for Bering Land Bridge National Preserve and Cape Krusenstern National Monument, 2022

    Metadata Updated: February 3, 2022

    Geospatial data for the Arctic Inventory and Monitoring Network (ARCN) Coastal Erosion Vital Sign monitoring program, updated in 2022 to be compatible with version 5 of the US Geological Survey Digital Shoreline Analysis System (DSAS). New DSAS transects were generated in 2022 to be compatible with DSAS version 5, and DSAS summary features were generated using these new transects.

    Shorelines digitized from four different imagery sources: (1) c. 1950, (2) c. 1980, and (3) 2003 aerial photographs, and (4) 2013-14 high-resolution satellite images. Stored as 1) ESRI Personal Geodatabases (*.mdb) in the format required to analyze using the US Geological Survey Digital Shoreline Analysis System (DSAS), and 2) shapefile exports of all layers in the geodatabases. These layers include water lines (wl), erosion lines (el), and vegetation lines (vl) from each of the four sampling episodes listed above, plus the baselines and transects used in DSAS to make shoreline rate of change measurements. The outer shore line DSAS databases were created by Manley and Lestak and water lines digitized for the first 3 sampling episodes (https://irma.nps.gov/DataStore/Reference/Profile/2184176). L. Farquharson digitized the water line for the 4th sampling episode, added the new erosion line feature, and digitized the erosion line for all for sampling episodes. In 2019, D. Swanson added new baselines and transects to sample the "inner shoreline" (lagoons) and digitized the vegetation line (vl) for all sampling episodes, and made minor edits to the erosion line data.(https://irma.nps.gov/DataStore/Reference/Profile/2263667)
