Description:

Abstract:

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.

Purpose:

This shoreline can be used as a base layer to represent the shoreline in GIS systems and maps.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

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).

Logical_Consistency_Report:

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.

Completeness_Report:

Spatial and attribute properties are believed to be complete, although attribute information has been simplified. Geometric thresholds from original data are preserved. No tests have been completed for exhaustiveness.

Lineage:

Process_Step:

Process_Description:

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. Lastly, the data were projected into the North American Datum(NAD) of 1983.

Enumerated_Domain_Value: User added line

Enumerated_Domain_Value_Definition:

Lines which are added to the vector coverage by the data entry operator and do not appear on the source map. 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.
