Maintaining a record of historical shoreline positions is an effective method to monitor national shoreline evolution over time, enabling scientists to identify areas most susceptible to erosion or accretion. These data can help coastal managers and planners understand which areas of the coast are vulnerable to change. This data release includes one new mean high water (MHW) shoreline extracted from lidar data collected in 2017 for the entire coastal region of North Carolina which is divided into four subregions: northern North Carolina (NCnorth), central North Carolina (NCcentral), southern North Carolina (NCsouth), and western North Carolina (NCwest). Previously published historical shorelines for North Carolina (Kratzmann and others, 2017) were combined with the new lidar shoreline to calculate long-term (up to 169 years) and short-term (up to 20 years) rates of change. Files associated with the long-term and short-term rates are appended with "LT" and "ST", respectively. A proxy-datum bias reference line that accounts for the positional difference in a proxy shoreline (e.g. High Water Line (HWL) shoreline) and a datum shoreline (e.g. MHW shoreline) is also included in this release. Purpose: This dataset consists of point data created by the Digital Shoreline Analysis System (DSAS) v5.1 at the intersection of shoreline and transect locations. Measurement transects are cast by DSAS from the baseline to intersect shoreline vectors, and the intersect data provide location and time information used to calculate rates of change. These point data contain identification information related to the DSAS transect (TransOrder) as well as the shoreline (ShorelineID and Uncertainty) and proxy-datum bias data (if applicable). They can be used to visually display which shorelines were used in the rate calculations and capture details on the shoreline represented by the intersection. The distances between the reference baseline and each shoreline intersection along a transect are used by the DSAS software to compute the shoreline change metrics.

Logical_Consistency_Report: These data were generated using DSAS v5.1, an automated software program, which does not perform checks for fidelity of the input features. Following generation of the rates and intersects by the DSAS software, a visual inspection of the intersects was performed in map view to determine that no unwanted measurements, such as those crossing man-made coastal structures, were included in the desired long-term (LT) or short-term (ST) shoreline change analysis. It is possible that a centimeter-scale offset may occur when projecting from outside of the spatial reference system used for analysis (UTM Zone 18N WGS84 or UTM Zone 17N WGS84). This is an artifact of the projection process; rate data are unaffected. Completeness_Report: This dataset contains the intersects automatically generated by the DSAS software application that were used to calculate shoreline change rates for the region. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The intersection points represent the location where transects cast by the DSAS software crosses a historical shoreline position. The positional uncertainties associated with the shoreline and intersection points are captured in the shoreline attribute table (see larger work citation, and NCsouth_shoreline_2017). See Kratzmann and others (2017) for uncertainties associated with historical (1848-2010) shoreline positions. Lineage: Process_Step: Process_Description: Step 1: Long-term (LT) rate calculations were performed producing rates and intersect points with and without the proxy-datum bias correction. DSAS parameters used: shoreline layer = NCsouth_shorelines, shoreline date field = Date_, shoreline uncertainty field name = Uncy, default accuracy = 5.1 meters, shoreline intersection = seaward, stats calculations = [LRR], shoreline threshold = 3, confidence interval=90%. Files produced = NCsouth_rates_LT, NCsouth_intersects_LT. The historical shoreline database contains both MHW and HWL shorelines thus a proxy-datum bias (PDB), stored as a line feature class is appended to the reference baseline. The PDB is applied during rate calculation. For more information about the origin of the PDB see Ruggiero and List (2009), which is cross-referenced in this metadata file. Rate statistics are presented with and without the PDB correction applied, denoted in the long-term rates attribute table (see larger work citation, NCsouth_rates_LT) with a prefix of “NB_” or “No bias”. The bias uncertainty values are stored within the bias feature attribute table (see larger work citation, NCsouth_bias_feature).
