Description:

Abstract:

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 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:

The datasets described by this metadata file include intersects of shoreline positions for the islands Vieques and Culebra, 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.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

The attributes of this dataset are based on the field requirements of the Digital Shoreline Analysis System and were automatically generated by the software during the generation intersect points.

Logical_Consistency_Report:

These data were generated using DSAS, an automated software program, which does not perform checks for fidelity of the input features. Following generation of the rates and intersects by the DSAS software a visual inspection of the intersects was performed in map view to determine that no unwanted measurements were included in the desired (long- or short-term) shoreline change analysis.

Completeness_Report:

This dataset contains the shoreline intersect positions generated by the DSAS software application that were used to calculate shoreline change rates for the region. Additional intersect positions and rate transects may have been generated but did not meet the required number of shorelines or time period requirements.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

The shoreline intersect points represent the location where transects cast by the Digital Shoreline Analysis System (DSAS) software crosses a vector shoreline position. They can be used to visually display which shorelines were used in the rate calculations and capture details on the shoreline represented by the intersection. The distances between the reference baseline and each shoreline intersection along a transect are used by the DSAS software to compute the shoreline change metrics. The positional uncertainties associated with the shoreline and intersection points are captured in the shoreline attribute table.

Process_Description:

To calculate the long-term shoreline change rate the entire range of shorelines from 1901 to 2018 were utilized. DSAS generates shoreline intersects and shoreline change calculations stored as rate transects. Depending on the available data, the shoreline intersects used for analysis may include those referenced to the datum-based mean high water (MHW) or a proxy-based feature such as the high water line (HWL) wet-dry line (WDL). Input parameters used: shoreline layer= PR_Shorelines, shoreline date field=Date_, shoreline uncertainty field name=Uncy, the default accuracy=10 meters, shoreline intersection=seaward, transect layer= VC_Trans_LT, stats calculations=[LRR], shoreline threshold=0, confidence interval=90%. Files produced and saved to personal geodatabase = VC_Trans_LT_rates, VC_Trans_LT_intersects. NOTE: All shorelines have an uncertainty value listed in the attribute table that provides the horizontal uncertainty associated with the shoreline, regardless of the method used. The shoreline database contains both MHW and HWL shorelines.
