This is a Vector data set. It contains the following vector data types (SDTS terminology):
Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.000000. Longitudes are given to the nearest 0.000000. Latitude and longitude values are specified in Decimal degrees.
The horizontal datum used is North American Datum of 1927.
The ellipsoid used is Clarke 1866.
The semi-major axis of the ellipsoid used is 6378206.400000.
The flattening of the ellipsoid used is 1/294.978698.
Sequential unique whole numbers that are automatically generated.
Coordinates defining the features.

Shoreline spatial data are considered a crucial element in land use planning, determination of boundary extents, performing change analysis for erosion and accretion studies, and other types of decision making. Within the scope of the U.S. Geological Survey DS 146, the detailed coastline provided here serves as a basemap to acurately portray the geographic locations of the samples in usSEABED in their relation to coastal zones and landforms.

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: Shoreline (1); Inland limit of mangrove swamp (6); Jetty, breakwater, or groin (27); Pier, ramp, or dock (30); Bridge (single line delineation) (59); Dam (65); Class I structure intact (73); User added arc (-9999); Dike, levee, jetty, breakwater, groin, or pier not labeled (-9998)
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. For the SDDEF data, no accuracy assessment was made since CSC received this information directly from NOAA-NGS.
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.
