![]() This process involved the conversion of original analog products to digital mapping products. The project intent was to rescue valuable historical data and make it accessible and useful to the coastal mapping community. The NOAA National Ocean Service, Office for Coastal Management, developed the procedures used in this project and was responsible for project oversight. ![]() The NOAA NESDIS Environmental Data Rescue Program (EDRP) funded this project. The individual coverages were ultimately edgematched within a surveyed project area and appended together. (ESRI)(r), ArcInfo's(r) ArcScan(r) software to create individual ArcInfo coverages. These vector data were created by contractors for NOS who vectorized georeferenced raster shoreline manuscripts using Environmental Systems Research Institute, Inc. These shoreline data represent a vector conversion of a set of NOS raster shoreline manuscript identified by t-sheet or tp-sheet numbers. These datasets may be beneficial for performing change analysis for erosion and accretion studies, land use planning, determination of boundary extent, and other types of decision making. These datasets have been cleaned and reformatted to support the efforts of supplying accurate shoreline data layers for a coastal GIS database. The shoreline and associated data layers were originally intended to support NOAA Nautical Chart production. 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. 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. 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. ![]() These data were automated to provide an accurate high-resolution historical shoreline of Yakutat and Vicinity, Alaska suitable as a geographic information system (GIS) data layer.
