Title: Shoreline for North Chandeleur Island, 1999
Abstract:
The U.S. Geological Survey (USGS), in cooperation with the Coastal Research Laboratory in the Department of Geology and Geophysics at the University of New Orleans (UNO) and the Center for Coastal Energy and Environmental Resources at Louisiana State University (LSU), is investigating the processes of coastal erosion and wetland loss in Louisiana (Sallenger and others, 1987; Sallenger and Williams 1989; Penland and others, 1992).
Building on the USGS Louisiana Barrier Island Study (Williams and others, 1992), this data layer depicts the North Chandeleur Island as is stood in 1999.
In order to quantify shoreline changes since 1989, new vertical aerial mapping photography was acquired in 1999. The methods and transects used by McBride and others (1992) were used to insure data compatibility of the new measurements and analysis .

Edits include, but are not limited to: Filled out the citation information including adding the suggested citation, adding the DOI link and a link to the data page. Fixed the currentness reference to the year applying to this dataset. Added USGS Thesaurus and ISO 19115 Topic Category theme keywords. Added the link to the browse graphic. Indicated in some required elements that information was unavailable from the original metadata. Additional small edits to the metadata were made to be consistent with current standards. Updated the distribution liability to an approved FSP disclaimer statement. Updated the distribution information to include download links. The metadata date was updated, but not the metadata contact. The metadata contact email was updated to a valid link with an explanation in the contact instructions. The metadata available from a harvester may supersede metadata available from the publication. Compare the metadata dates to determine which metadata file is most recent. A persistent identifier (PID) was added to the metadata in the thesaurus section. (20250814) Person who carried out this activity:
