Shoreline Data Rescue Project of Aleutian Islands and Delarof Islands, Alaska, AK318A

Published by National Geodetic Survey | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: December 08, 2025 | Last Modified: 2020-01-01T00:00:00.000+00:00
These data were automated to provide an accurate high-resolution historical shoreline of Aleutian Islands and Delarof Islands, Alaska suitable as a geographic information system (GIS) data layer. These data are derived from shoreline maps that were produced by the NOAA National Ocean Service including its predecessor agencies which were based on an office interpretation of imagery and/or field survey. The NGS attribution scheme 'Coastal Cartographic Object Attribute Source Table (C-COAST)' was developed to conform the attribution of various sources of shoreline data into one attribution catalog. C-COAST is not a recognized standard, but was influenced by the International Hydrographic Organization's S-57 Object-Attribute standard so the data would be more accurately translated into S-57.
