This dataset consists of long-term (greater than 60 years) shoreline change rates for the west coast of Alaska between Cape Prince of Wales and the Kotlik River. Rate calculations were computed within a GIS using the Digital Shoreline Analysis System (DSAS) version 5.1.2, an ArcGIS extension developed by the U.S. Geological Survey. Long-term rates of shoreline change were calculated using a linear regression or end point rate-of-change based on available shoreline data between 1949 and 2015. A reference ...

This dataset consists of short-term (less than 40 years) shoreline change rates for the west coast of Alaska between Cape Prince of Wales and the Kotlik River. Rate calculations were computed within a GIS using the Digital Shoreline Analysis System (DSAS) version 5.1.2, an ArcGIS extension developed by the U.S. Geological Survey. Short-term rates of shoreline change were calculated using an end-point method based on available shoreline data between 1980 and 2015. A reference baseline was used as the ...

This dataset consists of point data created by the Digital Shoreline Analysis System (DSAS) v5.1.2 at the intersection of shoreline and transect locations. Measurement transects are cast by DSAS from the baseline to intersect shoreline vectors, and the intersect data provide location and time information used to calculate rates of change. These point data contain identification information related to the DSAS transect (TransOrder) as well as the shoreline (ShorelineID and Uncertainty). They can be used to ...

This dataset includes reference baselines used by the Digital Shoreline Analysis System (DSAS) version 5.1.2 to calculate rate-of-change statistics for the exposed, open-ocean coast of western Alaska between Cape Prince of Wales to the Kotlik River for the time period 1949 to 2015. This baselines layer serves as the starting point for all transects cast by the DSAS application and can be used to establish measurement points used to calculate shoreline-change rates.

This dataset includes historical shoreline positions that span up to 66 years, from 1949 to 2015, for the west coast of Alaska between Cape Prince of Wales and the Kotlik River. Shorelines were compiled from aerial orthophotographs (U.S. Geological Survey (USGS); State of Alaska Division of Natural Resources, Division of Geological and Geophysical Surveys). Historical shoreline positions serve as easily understood features that can be used to describe the movement of beaches through time. These data are ...
