N.C. Division of Coastal Management 20101210 vector digital data withheld Shoreline_Structures THIS FILE WAS EDITED BY CURRITUCK COUNTY GIS BASED ON 2012 ORTHOPHOTOGRAPHY.This file represents polygon features associated with the estuarine shoreline in Currituck County, North Carolina. Polygon features are based on 2008 county level digital orthophotos that were flown between from May 30th and July 15th, 2008th, at 1/2 foot ground sample distance (GSD) 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." 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 Currituck 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). en REQUIRED: The year (and optionally month, or month and day) for which the data set corresponds to the ground. ground condition Complete None planned -76.194642 -75.765997 36.553840 36.071439 2828874.676682 2949999.969653 860289.171987 1032315.565334 None coastal estuarine sound shoreline apparent shoreline shoreline type ISO 19115 Topic Category Oceans 013 None Currituck County Place_Keyword Coastal counties Place_Keyword North Carolina Place_Keyword USA Place_Keyword North America None These data represent the location of polygon structures located along the estuarine shoreline in Currituck County based off of geo-rectified 2008 aerial orthophotos.

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." Bridge (STRUC_TYPE 31) Bridges are structures built to span bodies of water or other physical obstacles for the purpose of providing passage over the obstacle. Pier/Floating Dock/Wharf (STRUC_TYPE 51) Piers are pile supported, shore perpendicular structures that provides access over a water body. Floating docks are typically Timber, plastic, concrete or steel platforms used to moor vessels against and will rise and fall with the tides. Wharfs are pile supported, shore parallel structures that provide access over a water body, and are utilized to load or unload cargo from ships, or to provide platforms for commercial shipping infrastructure such as railroads, cranes, etc. Unknown (STRUC_TYPE 81) unknown structures represent any polygon structures unidentifiable from aerial photography, or that does not have an alternative STRUC_TYPE category (e.g. duck blinds).

Morehead City N.C. 28557 USA 252-808-2808 Downloadable Data 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. 7.613 20130731 Scott Geis N.C.
