Building on the USGS Louisiana Barrier Island Study (Williams and others, 1992), this data layer depicts the Caminada-Moreau shoreline as it stood in 1884.
In order to quantify shoreline changes since January 21, 1988, new vertical aerial mapping photography was acquired on December 9, 1996. The methods and transects used by McBride and others (1992) were used to insure data compatibility of the new measurements and analysis.
