These data were created by the National Ocean Service, National Geodetic Survey (previously the National Ocean Survey) as part of its ongoing mission to map the coastline of the United States. The NOAA National Ocean Service, Coastal Services Center developed the procedures used in this project and was responsible for project oversight. The project intent was to rescue valuable historical data and make it accessible and useful to digital mapping products. This file is a further conversion of that product from a raster to a vector product that may be useful for Electronic Charting and Display Information Systems (ECDIS) and geographic information systems (GIS). Online_Linkage: http:/www.csc.noaa.gov/products/shorelines Description: Abstract: These data were automated to provide a suitable geographic information system (GIS) data layer depicting the historical shoreline for Puerto Rico and the U.S. Virgin Islands. These data are derived from shoreline maps that were produced by the NOAA National Ocean Service including its predecessor agencies. Purpose: Shoreline spatial data are considered a crucial element in land use planning, determination of boundary extents, performing change analysis for erosion and accretion studies, and other types of decision making.

(ESRI)® ArcInfo® version 7.2.1 Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: The attribute accuracy was tested by creating checkplots of the coded linework. The different codes depict shoreline, piers, dikes, jetties, breakwaters, and groins. A light table review of the checkplots would reveal any inaccurate coding. Mistakes would be identified and corrected until accurate checkplots were produced. The feature codes (f-codes) are identified as follows: Shoreline (1); Inland limit of mangrove swamp (6); Jetty, breakwater, or groin (27); Pier, ramp, or dock (30); Bridge (single line delineation) (59); Dam (65); Class I structure intact (73); User added arc (-9999); Dike, levee, jetty, breakwater, groin, or pier not labeled (-9998) Logical_Consistency_Report: Linework was vectorized to the neatline of the shoreline map. All data crossing the neatline was clipped to the neatline. All arcs were snapped by the nodes to create consistently tied strings without node dangles. Completeness_Report: These shoreline data adequately represented the shoreline at the time of the survey. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The horizontal positional accuracy for the digital data was tested by producing checkplots of the vectorized data and overlaying it with a plot of the rasterized T-Sheet on a light table. Linework which appeared to be greater than a pen width off of the T-Sheet was considered in error, and revisions were made until new checkplots revealed an accurate depiction of the T-Sheet. For the SDDEF data, no accuracy assessment was made since CSC received this information directly from NOAA-NGS.

Process_Step: Process_Description: During the vectorization process, all adjoining shoreline maps in the project are displayed on a computer screen and the shoreline is traced and coded appropriately. Maps within a project generally adjoin and, therefore, there is significant agreement of linework across the borders of the shoreline maps. This results in fewer errors related to the edge-matching process. All lines are coded with the feature code (f-code) value, a feature name (f-name), the shoreline map number (t/tp-sheet#), the scale of the shoreline map, the survey date, and the date the spatial data were captured. SDDEF data were added in areas where there was older shoreline data to reflect the most current shoreline available. Lastly, the data were projected into the North American Datum (NAD) of 1983.
