NOAA's Medium Resolution Digital Vector Shoreline
NOAA's Medium Resolution Digital Vector Shoreline is a high-quality, Geographic Information System-ready, general-use digital vector data set originally created by the Strategic Environmental Assessments (SEA) Division of NOAA's Office of Ocean Resources Conservation and Assessment. The Medium Resolution Digital Vector Shoreline is now managed by the NOS Special Projects Office. Compiled from hundreds of NOAA coast charts, this product comprises over 75,000 nautical miles of coastline (nearly 2.5 million vertices), representing the entire conterminous United States of America. Alaska, the Hawaiian Islands, Puerto Rico, and all other interests and territories of the United States are not included in the collection.
These digital geographic boundary files are available for download from NOS SPO or may be ordered directly from SPO as an entire suite on CD-ROM.
