A GIS compilation of vector shorelines and coastal bluff edge positions, and associated rate-of-change data for Barter Island, Alaska

December 9, 2020

This dataset consists of rate-of-change statistics for the coastal bluffs and shorelines at Barter Island, Alaska, for the time period 1947 to 2020. Rate calculations were computed within a GIS using the Digital Shoreline Analysis System (DSAS) version 5.0, an ArcGIS extension developed by the U.S. Geological Survey. A reference baseline was used as the originating point for the orthogonal transects cast by the DSAS software. The transects intersect bluff edges and shorelines establishing measurement points, which are then used to calculate change rates.
