ABSTACT/DESCRIPTION

This coastline was originally digitzed from 1:250,000 USGS quadrangle maps.  It was a collective project 
passed from the Alaska Department of Natural Resources -- Division of Oil & Gas, to the North Slope 
Borough, to the National Oceanographic and Atmospheric Administration (NOAA), to the USGS/EROS 
Alaska Field Office, and back to Alaska DNR.  Several updates were made at Alaska DNR, most notably 
corrections to the Copper River, coding changes for Baird Inlet, and deletion of extraneous islands in the 
Aleutians.  This is the most detailed digital coastline coverage which is currently available for the entire 
state.
