This dataset includes one vector shapefile delineating the position of the shorelines at Barter Island, Alaska spanning seven decades, between the years 1947 and 2020. Shoreline positions delineated from a combination of aerial photography, declassified satellite photography, and very-high resolution satellite imagery can be used to quantify the movement of the shoreline through time. These data were used to calculate rates of change every 10 meters alongshore using the Digital Shoreline Analysis System (DSAS) version 5.0. DSAS uses a measurement baseline method to calculate rate-of-change statistics. Transects are cast from the reference baseline to intersect each shoreline, establishing measurement points used to calculate shoreline change rates.
These data are part of a series of data quantifying rates and patterns of shoreline change and coastal permafrost bluff retreat from 1947 to 2020 at Barter Island. Alaska.
Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government.
Although this Federal Geographic Data Committee-compliant metadata file is intended to document the dataset in nonproprietary form, as well as in Esri format, this metadata file may include some Esri-specific terminology.

Assessing patterns of annual change to permafrost bluffs along the North Slope coast of Alaska using high-resolution imagery and elevation models

The attributes in this table record positional and measurement uncertainties calculated during the process of delineating features from the imagery data as described in the process steps. The field names are based on the requirements for use within the Digital Shoreline Analysis System (DSAS) software (Himmelstoss and others, 2018).
Adjacent shoreline segments do not overlap and are not necessarily continuous. Shorelines were quality checked for accuracy. Any slight offsets between adjacent segments due to georeferencing and digitizing error are taken into account in the uncertainty calculations.
This file is complete and contains all segments used to calculate change rates where data were available. These data adequately represented the feature position at the time of the imagery.
Data have been delineated from aerial and satellite imagery acquired between 1947 and 2020, the horizontal accuracy of which varies with respect to the data source and the time period. Horizontal accuracy is represented by the UNCY attribute in the file, calculated following the methodology described in Gibbs and Richmond (2015).
A formal accuracy assessment of the vertical positional information in the dataset is not applicable.

Fodar imagery
Fodar imagery was used to delineate the top edge of the bluff and instantaneous land-water interface shoreline.
Shoreline positions were delineated from a combination of historical maps, aerial photography, declassified satellite photography, and very-high resolution satellite imagery spanning a 70-year period between 1947 and 2020. Spatial resolution of the datasets ranged from 0.08 to 4.1 m. Images were georeferenced and rectified using map coordinates, ground survey points, and/or image-to-image correlation of photo-identifiable ground features. A total root-mean-square rectification error was determined for each dataset based on the residuals. Vectors were digitized in a GIS from all data sources using standard editing tools in ArcMap 10.7 using criteria described in Gibbs and Richmond (2015) and Gibbs and others (2019). A total horizontal position uncertainty of the feature was determined as the quadrature sum of all uncertainties, including the georeferencing, digitizing, and RMSE on image rectification. Long-term shoreline change rates were calculated every 10 meters alongshore using the Digital Shoreline Analysis System 5.0 (Himmelstoss and others, 2018). All statistics were calculated. Additional details on methodology and uncertainty estimates can be found in Gibbs and Richmond (2015) and Himmelstoss and others (2018).
