Description:

Abstract:

During Hurricane Irma in September 2017, Florida and Georgia experienced significant impacts to beaches, dunes, barrier islands, and coral reefs. Extensive erosion and coral losses result in increased immediate and long-term hazards to shorelines that include densely populated regions. These hazards put critical infrastructure at risk to future flooding and erosion and may cause economic losses. The U.S. Geological Survey (USGS) Coastal and Marine Hazards Resources Program (CMHRP) is assessing hurricane-induced coastal erosion along the southeast US coastline and implications for vulnerability to future storms.

Purpose:

Shoreline positions were compiled prior to and following Hurricane Irma along the sandy shorelines of the Gulf of Mexico and Atlantic coasts of Florida and the coast of Georgia. Shoreline positions from the mid-1800s through 2018 were used to update the shoreline change rates for Florida and Georgia using the Digital Shoreline Analysis System (DSAS) software. The shoreline positions and updated shoreline change rates provide actionable information to homeowners, coastal communities, and managers of public and private properties to improve resiliency for long-term hazards.
Georgia (GA): The Georgia dataset includes shorelines from 161 years ranging from 1855 to 2016. Shorelines were compiled from topographic survey sheets (T-sheets; National Oceanic and Atmospheric Administration (NOAA)) and lidar (USGS/NOAA/National Aeronautics and Space Administration (NASA), NOAA/U.S. Army Corps of Engineers (USACE) National Coastal Mapping Program (NCMP)/Joint Airborne Lidar Bathymetry Technical Center of eXpertise (JALBTCX)).
Florida east coast (FLec): border with GA to Key Biscayne The FLec dataset includes shorelines from 166 years ranging from 1851 to 2017. Shorelines were compiled from topographic survey sheets (T-sheets; NOAA, NOAA/Florida Department of Environmental Protection (FLDEP)), aerial photographs (FLDEP/USGS), and lidar data (USGS/NASA, USACE/Federal Emergency Management Agency (FEMA), NOAA/USACE NCMP).
Florida west coast (FLwc): Anclote Key to Barefoot Beach The FLwc dataset includes shorelines from 159 years ranging from 1858 to 2017. Shorelines were compiled from topographic survey sheets (T-sheets; NOAA, NOAA/FLDEP), aerial photographs (FLDEP/USGS), and lidar data (USGS/NASA, USACE/FEMA, NOAA/USACE NCMP).
Florida panhandle (FLph): Bald Point State Park to the Alabama border The FLph dataset includes shorelines from 163 years ranging from 1855 to 2018. Shorelines were compiled from topographic survey sheets (T-sheets; NOAA, NOAA/FLDEP), aerial photographs (FLDEP), and lidar data (USGS/NASA, USACE/FEMA, NOAA/USACE NCMP).
Historical shoreline positions serve as easily understood features that can be used to describe the movement of beaches through time. These data are used to calculate rates of shoreline change in support of the U.S. Geological Survey's Coastal Change Hazards programmatic focus to maintain a national scale database of shoreline positions and rates. Long-term and short-term shoreline change rates were generated in a GIS using the Digital Shoreline Analysis System (DSAS) version 5. DSAS uses a measurement baseline method to calculate rate-of-change statistics. Transects are cast from the reference baseline to intersect each shoreline, establishing measurement points used to calculate shoreline change rates.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

The data provided here are a compilation of shorelines from multiple sources, spanning >150 years. The attributes are based on the requirements of the Digital Shoreline Analysis System (DSAS) software and have gone through a series of quality assurance procedures.

Logical_Consistency_Report:

Adjacent shoreline segments do not overlap and are not necessarily continuous. Shorelines were quality checked for accuracy. Any slight offsets between adjacent segments due to georeferencing and digitizing error are taken into account in the uncertainty of the shoreline position, as reported in the horizontal accuracy section of this metadata file.

Completeness_Report:

This shoreline file is complete and contains all shoreline segments used to calculate shoreline change rates along sections of the Florida panhandle (FLph) coastal region where shoreline position data were available. These data adequately represented the shoreline position at the time of the survey. Remaining gaps in these data, if applicable, are a consequence of non-existing data or existing data that did not meet quality assurance standards.
The digitized shoreline vectors downloaded from NOAA included attributes defining the shoreline type (attribute field name varies by file). For the open-ocean coasts, only shoreline features (Natural.Mean High Water; SPOR; 20) were retained. Other shoreline features (such as seawalls, bulkheads, manmade objects) were deleted.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

The horizontal accuracy of the shoreline data varies with respect to the data source from which the shorelines were digitized, the lidar data from which the shorelines were extracted, and the time period. Georgia and Florida: Shorelines prior to 1960 (T-sheets) have an estimated positional uncertainty of plus or minus 10.8 meters. Shorelines from the 1960s-1980s (T-sheets) have an estimated positional uncertainty of plus or minus 5.1 meters. Shorelines from the 1950s-1970s (FLDEP, air photos) have an estimated positional uncertainty of plus or minus 3.2 meters. See below for average estimated uncertainty values for shorelines extracted from lidar. All lidar shorelines new to the FL/GA dataset have uncertainty recorded on a segment-by-segment basis in the attribute table (i.e., all except 1998/2001 and 1999 which are from data releases doi:10.5066/F74X55X7 and doi:10.5066/F78P5XNK, 2017). See the Uncy field in the shoreline attribute table for individual values.
GEORGIA (GA; average estimated positional uncertainty of lidar shorelines): 1999 = plus or minus 4.4 meters 2006 = plus or minus 3.2 meters 2010 = plus or minus 4.2 meters 2016 = plus or minus 5.5 meters
FLORIDA EAST COAST (FLec; average estimated positional uncertainty of lidar shorelines): 1999 = plus or minus 2.8 meters 2006 = plus or minus 1.9 meters 2009 = plus or minus 1.8 meters 2010 = plus or minus 2.7 meters 2016 = plus or minus 2.8 meters 2017 = plus or minus 2.9 meters
FLORIDA WEST COAST (FLwc; average estimated positional uncertainty of lidar shorelines): 1998 = plus or minus 1.7 meters 2010 = plus or minus 2.2 meters 2015 = plus or minus 2.0 meters 2017 = plus or minus 2.2 meters
FLORIDA PANHANDLE (FLph; average estimated positional uncertainty of lidar shorelines): 1998/2001 = plus or minus 1.4 meters 2010 = plus or minus 2.6 meters 2015 = plus or minus 1.7 meters 2016 = plus or minus 1.0 meters 2018 = plus or minus 2.7 meters

Process_Step:

Process_Description:

Data from the previously-published National Assessment of Shoreline Change study for the sandy shorelines of the Gulf of Mexico and Southeast Atlantic Coasts (USGS Open-File Report 2004-1089 and USGS Open-File Report 2005-1326) as well as the update reports (doi:10.5066/F74X55X7 and doi:10.5066/F78P5XNK, both in 2017) were used as the starting point for this update which includes several new lidar shorelines for Georgia and Florida. The previously published lidar shorelines are from 1998, 1999, and 2001.

Process_Step:

Process_Description:

A profile method was used to extract the operational MHW shoreline from the lidar point cloud data utilizing the Matlab-based approach (Matlab version 2019b) described in Farris and others (2018). Elevation values for the height of MHW were obtained from Weber and others (2005). The profile method used a coast-following reference line with 20-meter spaced profiles. All lidar data points that were within 1 meter of each profile line were associated with that profile. All processing was done on the 2-meter-wide profiles, working on a single profile at a time. For each profile, a linear regression was fit through data points on the foreshore and the regression was evaluated at the MHW elevation to yield the cross-shore position of the MHW shoreline. If there was a data gap at MHW or if the MHW elevation was obscured by water points, the linear regression was simply extrapolated to the MHW elevation. For each profile, the foreshore beach slope was defined as the slope of the regression line.
Each MHW shoreline point that was extracted using this profile method has an uncertainty associated with it. This uncertainty includes three components: 1) the 95% confidence interval on the linear regression estimate of the shoreline position; 2) a 15 cm vertical error in the raw lidar data that was converted into a horizontal error using the beach slope; and 3) the uncertainty due to extrapolation (if the shoreline was determined using extrapolation). These three components of uncertainty were added in quadrature to yield a total error for each shoreline point.

Lidar shorelines were extracted by Amy Farris, Kathy Weber, Zehao Xue, and Marie Bartlett of the USGS from 2015 through 2020 using the method described in this step.

Process_Description:

The lidar shoreline shapefiles were then visually checked against imagery contained in Esri's World_Imagery GIS server to make sure the shoreline was not interpolated through a headland or structure, for example. Attribute fields were added (based on DSAS requirements described in the DSAS v5 User Guide) to the attribute table and those fields were populated with the relevant information.
This process step and all other process steps were performed by the same person - Meredith Kratzmann.
