Description:

Abstract:

The Storm-Induced Coastal Change Hazards component of the National Assessment of Coastal Change Hazards project focuses on understanding the magnitude and variability of extreme storm impacts on sandy beaches. Lidar-derived beach morphologic features such as dune crest, toe and shoreline help define the vulnerability of the beach to storm impacts. This dataset defines the elevation and position of the seaward-most dune crest and toe and the mean high water shoreline derived from the 2013 Dauphin Island (Alabama) USGS lidar survey. Beach width is included and is defined as the distance between the dune toe and shoreline along a cross-shore profile. The beach slope is calculated using this beach width and the elevation of the shoreline and dune toe.

Purpose:

To provide data on the morphology of U.S. sandy beaches. Data were collected during USGS field activity number (FAN) 13CNT01; additional survey details are available at http://cmgds.marine.usgs.gov/fan_info.php?fan=13CNT01.

Microsoft Windows 7 Version 6.1 (Build 7600); Esri ArcGIS 10.0.4.4000; MATLAB 2014a

Data_Quality_Information:

Logical_Consistency_Report:

Morphologic features are QA/QC'd in ArcMap and edited in MATLAB, if needed.

Completeness_Report:

This dataset is considered complete for the information presented as described in the abstract section. Users are advised to read the rest of the metadata record carefully for additional details.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Horizontal accuracy is estimated for shorelines only by calculating the 95% confidence interval of the regression line through the shoreline position and is dependent on foreshore slope, scatter in the lidar data points, and specified lidar point uncertainty.

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report:

Vertical accuracy is determined for each dune crest and toe value based upon the scatter of data in the lidar grid cell.

A lidar survey that was used to estimate dune morphology variables.

Process_Step:

Process_Description:

Elevation data points from the lidar survey were interpolated in MATLAB 2014a to a gridded domain (segment) that was rotated parallel to the shoreline and had a resolution of 10 meters (m) in the longshore direction and 2.5 m in the cross-shore direction. The interpolation method applies spatial filtering with a Hanning window that is twice as wide as the grid resolution. Dune crest, toe and shoreline are extracted from the elevation grid in MATLAB every 10 m alongshore (each grid row is a profile). For details on feature extraction see: http://pubs.usgs.gov/of/2012/1084/.
