Abstract:
This file represents polygon features associated with the estuarine shoreline in North Carolina.  Polygon features are based on 2006-2010 county level digital orthophotos that were flown between from March 3rd to March 5th, 2007, at 3 inch to 1 foot resolution.  Polygon features were generated from the imagery through heads up digitizing, and were digitized at a scale between 1:300 and 1:500 feet.  Structure type is based on the presence of commercial, recreational and erosion control structures and attributed using guidance provided in a N.C. Division of Coastal Management generated methodology entitled, "Charting the Estuarine Environment: A methodology spatially delineating a contiguous, estuarine shoreline of North Carolina."
Purpose:
The North Carolina Division of Coastal Management (DCM) has specific needs to establish a detailed estuarine shoreline (including the identification of shoreline related structures) for non-regulatory purposes that can serve as a basis for examining DCM's existing policy language within its estuarine and ocean system areas of environmental concern (AEC).  This shapefile represents shoreline associated polygon structures (i.e. docks, piers, bridges, etc.) for Dare County that may be located along the land/water or vegetation/water interfaces.
This dataset was created to assist governmental agencies and others in making resource management decisions through the use of a Geographic Information System (GIS).

Overview_Description:
Entity_and_Attribute_Overview:
Shoreline types captured by DCM's Estuarine Shoreline Mapping Project are broken down into the following categories.  A brief explanation of each shoreline type follows its name.  Explanations for the various shoreline types are taken from a DCM report by Geis and Bendell entitled, "Charting the Estuarine Environment: A mehthodology spatially deleneating a contiguous, estuarine shoreline of North Carolina."

Resource_Description: Downloadable Data
Distribution_Liability:
The North Carolina Estuarine Shoreline Mapping Project is a multiyear initiative designed to increase awareness of existing shoreline types and the prevalence of hardened structures along the North Carolina estuarine coastline.  This effort will not result in the production of a complete hydrographic dataset for the coastal/estuarine environment.  The final data set generated through the ESMP will not be used as a regulatory line and therefore may not be applicable to litigation entered into by the state or agencies within DENR.  While efforts have been made to ensure that these data are accurate and reliable, DCM cannot assume liability for any damages, or misrepresentations, caused by any inaccuracies in the data, or as a result of the data to be used on a particular system.  DCM makes no warranty, expressed or implied, nor does the fact of distribution constitute such a warranty.  These data represented in an estuarine shoreline are believed to be logically consistent, though no    tests were performed.  All arcs are snapped by the nodes to create consistently tied strings without node dangles and to ensure line geometry is topologically clean.  While this shoreline dataset is dependent on aerial imagery taken for the 20 coastal counties prior to 2010, DCM understands that the position of the shoreline might change as the natural land changes or as better maps and more recent imagery become available.
