Description:

Abstract:

Breton Island, Louisiana Transects with Shoreline Change Rates (Pre-1950s) (Geographic, NAD83) consists of vector transect data that were derived from the Digital Shoreline Analysis System (DSAS) version 4.0. Rates from the DSAS statistical output table were joined to the transects to provide a visual representation of the shoreline change rates on a transect-by-transect basis.

Purpose:

Transect data are considered a crucial element in performing change analysis for erosion and accretion studies and for tracking shoreline movement over time. DSAS uses transects as a method to extract shoreline change rates from shorelines at a given interval across a baseline. For this long term analysis, transects were spaced out at a 50-m interval across the baseline and shoreline change rates were calculated for the historical long-term (Pre-1950s). Transect and rate attribute tables were joined to allow the rate values to be visualized on a map.

Data_Set_Credit:

Funds for this report are part of project funds for the Louisiana Outer Coast Early Restoration Project, obtained by the natural resource trustees for the Deepwater Horizon Oil Spill, pursuant to the Framework for Early Restoration Addressing Injuries Resulting from the Deepwater Horizon Oil Spill executed April 20, 2011. USFWS is the project lead for the North Breton Island Barrier Island Restoration project. Acknowledgment of the U.S. Geological Survey, St. Petersburg Coastal and Marine Science Center, as a data source would be appreciated in products developed from these data, and such acknowledgment as is standard for citation and legal practices. Sharing of new data layers developed directly from these data would also be appreciated by the U.S. Geological Survey staff. Users should be aware that comparisons with other datasets for the same area from other time periods may be inaccurate due to inconsistencies resulting from changes in photointerpretation, mapping conventions, and digital processes over time. These data are not legal documents and are not to be used as such.

Data_Quality_Information:

Logical_Consistency_Report:

Transects were generated as a product of the DSAS program at a 50-m interval. These transects were checked to ensure an even distribution and coverage of the shoreline datasets.

Completeness_Report:

Transects with errors or no rate values for all statistic fields were removed to ensure that only valid rates of change were used in the analysis. Errors included "null" and "0" values, which represent a transect that crossed only 0 or 1 shoreline and skewed the results. When joining the rates to the transect attribute table, the WLR and LRR fields could not contain a "null" value so null values are represented as a "-9999". These values should be checked and removed if using in any further analysis. The remaining transects with rates were used to aid in the final shoreline change results.

Source_Contribution: DSAS was used to generate the transects at a 50-m interval.

Process_Step:

Process_Description:

A single transect file was created and five copies were created, one for each of the analysis time periods of: (1) 1869-2014 (long-term), (2) pre-1950s (before excavation of the MRGO), (3) post-1950s (post MRGO), (4) post-Hurricane Katrina (2005-2014) (short-term), and (5) pre/post Hurricane Katrina (2004-2005)(acute weather event). Transects were generated at a 50-meter interval perpendicular to the baseline and consisted of 211 transects. Transects were removed in areas where less than two shorelines were present. Rates of change were calculated for: (1) net shoreline movement (NSM); (2) shoreline change envelope (SCE); (3) end point rate (EPR); (4) linear regression rate (LRR), and (5) weighted linear regression rate (WLR) and saved to a table, in the ArcGIS personal geodatabase format. The rate table generated by DSAS was then joined to the respective transect file so the rate values could be displayed on a map. In joining the rates to the transect table, the WLR and LRR fields were not able to use a "null" value so null values are represented as a "-99999". These values should be checked and removed if using in any further analysis.
