48238 NOAA_composite_shoreline Data Set Published / External 37236 ParentRecords Project Completed 2007-09-17 The NOAA Composite Shoreline is primarily intended for high-resolution cartographic representation of the shoreline. It is a high-resolution vector shoreline based on a multi-temporal collection of NOAA coastal survey maps (T-sheets). Where T-sheets were unavailable, NOAA's extracted vector shoreline (EVS) was used to compile seamless shoreline coverage. This shoreline can be used as a base layer to represent the shoreline in GIS systems and maps. 10854 The NOAA NESDIS Environmental Data Rescue Program (EDRP) and Climate Database Modernization Program (CDMP) funded this project. The data were created by the National Ocean Service, National Geodetic Survey (previously the National Ocean Survey) as part of its ongoing mission to map the coastline of the United States. The NOAA National Ocean Service, Office for Coastal Management, developed the procedures used in this project and was responsible for project oversight. The project intent was to rescue valuable historical data and make it accessible and useful to the coastal mapping community. This process involved the conversion of original analog products to digital mapping products.

Reasons for the added lines vary. The most common reason is that double banked streams may abruptly stop on the source map due to lack of aerial photography. In order for polygons to be made and distinction given to areas of water vs land, the "dangling" ends of these streams must be connected together by an arbitrary "phantom" line that holds no special meaning. | Neatline: Lines that represent the bounding area of a shoreline map. These are collected so that all area may contain a polygon label point that determines if the area is land, water, or man-made. | Approximate shore: Linework that represents the approximate location of shoreline on the source map. This is assigned to linework that may be obscured by man-made features such as bridges or large piers. The data entry operator does not have an actual line to vectorize from the source map, but can make a "highly educated guess" as to the actual location of the line. | Apparent shore: Linework that represents the shoreline that would appear to a mariner and the location of the shoreline shown on the source map. This is assigned to linework when the natural shoreline is obscured by vegetation. | SPOR: Linework that represents the "Shoreline Plane of Reference" or SPOR on the source map. This is assigned to linework that delineates natural and man-made shoreline. | Dike or levee: Linework that represents a dike or levee on the source map. | Jetty, breakwater, or groin: Linework that represents a jetty, breakwater, or groin on the source map. | Shore/Along Feat Bnd: Linework that represents shoreline behind man made features on the source map. | Pier, ramp, or dock: Linework that represents a pier, ramp, or dock on the source map. | Gen. manmade object: Linework that represents various types of man-made objects on the source map. This is assigned to man-made objects that appear along shorelines that may include wells or oil platforms, wrecks | Control point: Linework that represents the location of a geodetic control point placed by the NOAA NOS National Geodetic Survey. The representative triangle symbol vectorized from the source map illustrates the location of the control point in the center of the triangle with the name of the control point annotated on the map. | State Water: A one degree buffer from the shoreline out to the open water | State Boundary: The landward boundary of the state obtained from 1:1000,000 USGS Digital Line Graphs (DLGs) | 3 T-SHEET# Unknown No No Active Map number | Description Source: User defined Character field 4 INDEX# Unknown No No Active T-sheet Project number | Description Source: User defined Character field 5 SCALE Unknown No No Active Scale of source map | Description Source: User defined Numeric field 6 SURVEYDATE Unknown No No Active date of survey | Description Source: User defined Numeric field 7 GISDATE Unknown No No Active Date of data capture | Description Source: User defined Numeric field 49161 (state abbreviation)shr.pat Published / External Completed Polygon Attribute Table | Description Source: None Converted from FGDC using 'fgdc_to_inport_xml_entity.pl' script. 1 F-NAME VARCHAR No No Active Shoreline feature name. | Description Source: NOAA NOS Water: Polygon identifying area containing water. | Land: Polygon identifying area containing land. | Manmade: Polygon identifying area created by man (i.e. pier) | Data Steward 2007-09-17 Organization NOAA Office for Coastal Management NOAA/OCM coastal.info@noaa.gov 2234 South Hobson Ave Charleston SC 29405-2413 (843) 740-1202 https://coast.noaa.gov NOAA Office for Coastal Management Home Page Online Resource Distributor 2007-09-17 Organization NOAA Office for Coastal Management NOAA/OCM coastal.info@noaa.gov 2234 South Hobson Ave Charleston SC 29405-2413 (843) 740-1202 https://coast.noaa.gov NOAA Office for Coastal Management Home Page Online Resource Metadata Contact 2007-09-17 Organization NOAA Office for Coastal Management NOAA/OCM coastal.info@noaa.gov 2234 South Hobson Ave Charleston SC 29405-2413 (843) 740-1202 https://coast.noaa.gov NOAA Office for Coastal Management Home Page Online Resource Point of Contact 2007-09-17 Organization NOAA Office for Coastal Management NOAA/OCM coastal.info@noaa.gov 2234 South Hobson Ave Charleston SC 29405-2413 (843) 740-1202 https://coast.noaa.gov NOAA Office for Coastal Management Home Page Online Resource Publication Date -173.97 -64.56 49 -17.67 Range 1901 1995 Yes Unclassified To download the shoreline in its entirety, see the Shoreline Data download page (http://shoreline.noaa.gov/data/datasheets/composite.html).; None These data were generated for use by NOAA during the course of its development of potential final products to fulfill its statutory mission.

Contact Tyler Christensen (NOS) for details. 2018-02-08 Partial upload of Positional Accuracy fields only. The attribute accuracy was tested by creating checkplots of the coded linework. The different codes depict shoreline, piers, dikes, jetties, breakwaters, and groins. A light table review of the checkplots would reveal any inaccurate coding. Mistakes would be identified and corrected until accurate checkplots were produced. The feature codes (f-codes) are identified as follows: approximate shoreline (1), apparent shoreline (3), shoreline plane of reference (SPOR) (7), dike or levee (25), jetty, breakwater, or groin (27), shoreline along feature boundaries (28), pier, ramp, or dock (30), general class for man-made objects that form a shore or waterline to include - wells or oil platforms, wrecks, locks, dry docks, revetments, seawalls, wharves, marine railroads, or shorelines of seaplane bases or anchorages (38), control point or shoreline map correction line (139), map extent line (-1000), user added arc (-9999), state boundary (-9997), state water (-9996). The horizontal positional accuracy for the digital data was tested by producing checkplots of the vectorized data and overlaying it with a plot of the rasterized T-Sheet on a light table. Linework which appeared to be greater than a pen width off of the T-Sheet was considered in error, and revisions were made until new checkplots revealed an accurate depiction of the T-Sheet. These shoreline data adequately represented the shoreline at the time of the survey. Linework was vectorized to the neatline of the shoreline map. All data crossing the neatline was clipped to the neatline. All arcs were snapped by the nodes to create consistently tied strings without node dangles. 1 During the vectorization process, all adjoining shoreline maps in the project are displayed on a computer screen and the shoreline is traced and coded appropriately. Maps within a project generally adjoin and, therefore, there is significant agreement of linework across the borders of the shoreline maps. This results in fewer errors related to the edge-matching process. Polygon labels and attributes are assigned to features containing area so that users may shade the data to determine land and water. All lines are coded with the feature code (f-code) value, a feature name (f-name), the shoreline map number (t/tp-sheet#), the scale of the shoreline map, the survey date, and the date the spatial data were captured. After the edgematching process is complete, the state boundary was added, as was a one-degree buffer of the shoreline on the seaward side. This allowed for polygons to be created and attributed with the appropriate feature name (land/water). Process Date Range is 2000 - present. 2007-09-17T00:00:00 49161 Entity 49160 Entity gov.noaa.nmfs.inport:48238 Anne Ball 2017-11-14T14:33:47 SysAdmin InPortAdmin 2025-05-15T19:16:05 2018-02-08 Office for Coastal Management OCM 1002 Public No No 2018-02-08 1 Year 2019-02-08
