Henderson, R.E., Heslin, J.L., and Himmelstoss, E.A., 2021, Puerto Rico shoreline change — A GIS compilation of shorelines, baselines, intersects, and change rates calculated using the Digital Shoreline Analysis system version 5.1 (ver. 2.0, March 2023): U.S. Geological Survey data release,


The U.S. Geological Survey (USGS) maintains shoreline positions for the United States coasts from both older sources, such as aerial photographs or topographic surveys, and contemporary sources, such as lidar-point clouds and digital elevation models. These shorelines are compiled and analyzed in the USGS Digital Shoreline Analysis System (DSAS), version 5.1 software to calculate rates of change. Keeping a record of historical shoreline positions is an effective method to monitor change over time, enabling scientists to identify areas most susceptible to erosion or accretion. These data can help coastal managers understand which areas of the coast are vulnerable to change. This data release, and other associated products, represent [...]

This dataset contains shorelines (1900s to 2018), baselines, shoreline change rates and intersects (both long-term and short-term) for the coastal region of Puerto Rico, including the islands of Vieques and Culebra. Depending on the location, the analysis may include as few as three shorelines or up to 16, based on the availability and quality of shoreline data.
