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 an expansion of the USGS national-scale shoreline database to include Puerto Rico and its islands, Vieques and Culebra. The USGS, in cooperation with the Coastal Research and Planning Institute of Puerto Rico—part of the Graduate School of Planning at the University of Puerto Rico, Rio Piedras Campus—has derived and compiled a database of historical shoreline positions using a variety of methods. These historical shoreline data are then used to measure the rate of shoreline change over time. Rate calculations are computed within a geographic information system (GIS) using the DSAS version 5.1 software. Starting from a user defined baseline, measurement transects are created by DSAS that intersect the shoreline vectors. The resulting intersections provide the location and time information necessary to calculate rates of shoreline change. The overall project contains shorelines, baselines, shoreline change rates (long-term and short-term), and shoreline intersects (long-term and short-term), for Puerto Rico, and the adjacent islands of Vieques and Culebra. Purpose: This dataset includes shorelines for ~120 years ranging from 1901 to 2018 for the coastal region of Puerto Rico, including the islands of Vieques and Culebra. Historical shorelines were compiled from a variety of sources including T-sheets, orthophotos, aerial photos, and lidar data. Supplemental_Information: Version 2.0 contains all shorelines released in the first version with the addition of a lidar shoreline from 2014/2015 (Heslin and others, 2021).

The attributes are based on the requirements of the Digital Shoreline Analysis System (DSAS) software and have gone through a series of quality assurance procedures. Logical_Consistency_Report: Adjacent shoreline segments do not overlap and are not necessarily continuous. Shorelines were quality checked for accuracy. Minor offsets (less than 10 m) between adjacent segments due to georeferencing and digitizing error are taken into account in the uncertainty of the shoreline position, as reported in the horizontal accuracy section of this metadata file. Where an obvious major offset (greater than 10 m) could be determined, the shoreline in question was removed from analysis. Completeness_Report: This shoreline file is complete and contains all shoreline segments used to calculate shoreline change rates along sections of Vieques, Culebra and the main island of Puerto Rico where shoreline position data were available. Depending on the location, there may be as few as two shorelines, or up to 16 based on the availability and quality of available shoreline data. These data adequately represented the shoreline position at the time of the survey. Gaps in these data, if applicable, are a consequence of non-existing data or existing data that did not meet quality assurance standards. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Shoreline data have been acquired from four different data releases. The horizontal accuracy varies with respect to the data source from which the shorelines were digitized and the time period. Please see individual, associated publications (listed in the source citations below) for calculations of horizontal positional uncertainty.
