Satellite-Derived Shorelines for Five Groin Field Sites Across the United States

This data release provides tidally corrected shoreline positions for five groin field sites of around the United States (Ventura, CA, Newport Beach, CA , Santa Monica, CA, Long Branch, NJ, Sandwich, MA). Both CSV files of tidally corrected shorelines and GeoJSON files of the region of interests (ROIs), transects, and reference shorelines are provided within respective zip files. Both file types are derived from the software CoastSeg (Fitzpatrick and others, 2024). CoastSeg collects satellite images from Google Earth Engine to create shoreline data along with user supplied inputs based on the CoastSat methodology (Vos and others, 2019). Data have been tidally corrected based on beach foreshore slopes.
