A baseline was acquired from the Barrier Island Comprehensive Monitoring Program (BICM) 2009 report (http://lacoast.gov/reports/project/3890772~1.pdf). The baseline included in the BICM report covered the entire Louisiana coastline, so the baseline representing Breton Island had to be clipped then exported to a new shapefile named Breton_Baseline.shp. The position relative to Breton Island was determined to be the best possible baseline to use for the study. The baseline file was used to create the transect files, which are required by the DSAS program to calculate rate of change statistics. Purpose: The baseline was digitized as a single vector line parallel to, and seaward of, the Breton Island shorelines. The baseline serves as a starting point for the DSAS program to cast transects. For this analysis, transects were spaced out at a 50-meter (m) interval across the baseline.

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.

Process_Step: Process_Description: The baseline data downloaded from the BICM 2009 report encompassed the entire state of Louisiana; however, this project’s study area was restricted to Breton Island. Therefore, the BICM baseline was clipped using ArcMap 10.2 to match the study area extents, prior to the baseline being exported to a new shapefile named Breton_Baseline.shp. Breton_Baseline.shp was used to analyze the following time periods: (1) 1869-2014 (long term), (2) pre-1950s (before excavation of the MRGO), (3) post- 1950s (post MRGO), (4) post- Hurricane Katrina (short term), and (5) pre/post Hurricane Katrina (acute weather event). The baseline was used to generate perpendicular transects at a 50-m interval.
