These data were automated to provide an accurate high-resolution historical shoreline of Biddeford Pool, Maine To Cape Ann, Mass. 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.

This dataset contains boundary layers for Rachel Carson National Wildlife Refuge: Biddeford Pool Division.

National Wildlife Refuges are federal lands managed by the U.S. Fish and Wildlife Service (USFWS). The primary source for boundary information is the USFWS Realty program (status maps, legal surveys). An effort by the USFWS Region 5 (northeast states - ME,NH,VT, MA, RI, CT, NY, PA, NJ, MD, DE, WV, VA) Realty Division, Cartography and Spatial Data Services Branch has resulted in digital refuge boundaries for all refuges in the northeast at a scale of 1:24,000.

The intended application of the data is to serve as a spatial reference of refuge boundaries for other data layers in GIS and mapping applications. It is specifically not intended to be used as a land survey or representation of land for conveyance or tax purposes.

Status maps were registered to geographic coordinates, boundaries were digitized and labeled. Digital files were updated using survey and collateral data, then stepped through 3 levels of quality-control review for spatial and thematic accuracy.
