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.
