World Vector Shoreline Text Label Points

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.

VMAP data set products use the "vector product format" (vpf) utilized first by the US Defense Mapping Agency and later by its successor, the National Imagery and Mapping Agency (NIMA, now known as the NGA). "VMap" is derived from "Vector Smart Map."
