- Abstract:
-
The shoreline of Cape Hatteras, North Carolina, is experiencing long-term coastal erosion. In order to better understand and monitor the changing coastline, historical aerial imagery is used to map shoreline change. For the area of Hatteras Island from Cape Point to Oregon Inlet, fourteen aerial datasets from 1978-2002 were scanned and georeferenced for use in a Geographic Information System (GIS). Shoreline positions (high water line) were digitized from georeferenced imagery. The shoreline vectors were then compiled for use in the Digital Shoreline Analysis System (DSAS) ArcGIS extension in order to generate rates of shoreline change.
- Purpose:
-
This dataset consists of orthogonal transects and shoreline change rates for Hatteras Island, from Oregon Inlet to Cape Hatteras Point, North Carolina. Rate calculations were computed within a GIS using the Digital Shoreline Analysis System (DSAS) version 4.3, an ArcGIS extension developed by the U.S. Geological Survey. Long-term rates of shoreline change were calculated using a linear regression rate based on all available shoreline data. A reference baseline was used as the originating point for the orthogonal transects cast by the DSAS software. The transects intersect each shoreline establishing measurement points, which are then used to calculate long-term rates.

We would also like to thank Bill Berkemeier and Jesse McNinch of the USACE Field Research Facility for providing access to the aerial photograph library. Jeff List contributed to the formulation of the uncertainty calculations for the rates of change, and the initial concept for deriving a shoreline database from the FRF historic photographs came from Rob Thieler, as part of the USGS North Carolina Coastal-Change Processes project.

- Attribute_Accuracy_Report:
-
The attributes in this layer are based on the requirements for use within the Digital Shoreline Analysis System (DSAS) software (USGS Open-File Report 2008-1278). The data have been quality checked and the attribute value (TransOrder) increments sequentially alongshore.
- Logical_Consistency_Report:
-
These data were generated using DSAS v4.3, an automated software program, which does not perform checks for fidelity of the input features. The transects were visually inspected and sometimes manually adjusted within a standard ArcMap edit session to adjust the position at which an individual transect intersected the shorelines.
- Completeness_Report:
-
This dataset contains transects automatically generated by the DSAS software application that were used to calculate long-term shoreline change rates for the region.

The linear regression rate of shorelines from 1978-2002. A linear regression rate-of-change statistic was calculated by fitting a least-squares regression line to fourteen shorelines from 1978 to 2002 for each transect. The best-fit regression line is placed so that the sum of the squared residuals (determined by squaring the offset distance of each data point from the regression line and adding the squared residuals together) is minimized. The linear regression rate is the slope of the line. The rate is reported in meters per year with positive values indicating accretion and negative values indicating erosion.
