- Abstract:
- The World Vector Shoreline (WVS) dataset was developed by the National Imagery and Mapping Agency (formerly the U.S. Defense Mapping Agency - DMA) as a digital data file, at a nominal scale of 1:250,000 and referenced to the World Geodetic System (WGS-84) datum. The WVS is divided into ten ocean basin area files. This data layer is a subset of the Western North Atlantic region and provides a shapefile of countries bordering the Gulf of Mexico and Caribbean Sea, and the islands of the Caribbean Sea region.
- Purpose:
- This dataset was created by the World Resources Institute for the purposes of the Reefs at Risk Caribbean Project (<http://reefsatrisk.wri.org/>). This ArcView shapefile may be used as a general basemap data layer to illustrate coastlines of countries bordering the Gulf of Mexico and Caribbean Sea, and the islands of the Caribbean Sea region. It may be utilized in any Geographic Information System (GIS).

- Source_Contribution:
- The main source material for the WVS was DMA's Digital Landmass Blanking (DLMB) database which was derived primarily from the Joint Operations Graphics and coastal nautical charts produced by DMA. The DLMB data consisted of a land/water flag file on a 3 by 3 arc-second interval geographic grid. This raster database was converted into vector form to create WVS and explains the 3 arc-second stepping interval apparent in the coastline when plotted out at high scale. For areas of the world not covered by the DLMB database, the shoreline was taken from the best available hard copy sources at a preferred scale of 1:250,000 (or up to 1:125,000 where the source data allowed).
The DMA WVS datasets were compiled into separate 'coast' format data files for use with the USGS Coastal and Marine Geology Program cartographic plotting program MAPGEN during the 1980's. These 'coast' format files were the source to retrieve the WVS datasets and is the result of what is presented here.
