Summary

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 [...]

Purpose

The datasets described by this metadata file include intersects of shoreline positions for the main island of Puerto Rico, used for both long-term (~120 years) and short-term (~40 years) shoreline change calculations. Rate calculations were computed within a GIS using DSAS version 5.1, an ArcGIS extension developed by the U.S. Geological Survey. A reference baseline was used as the originating point for the orthogonal transects cast by the DSAS software. The transects intersect each shoreline establishing measurement points which provide location and time information used to calculate rates of change. Long-term and short-term rates of shoreline change were calculated using a linear regression rate based on available shoreline data.
Extent of shoreline intersects for long-term shoreline change rates.
