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.
Shoreline data are considered a crucial element in performing change analysis for erosion and accretion studies and for tracking shoreline movement over time; lidar data was downloaded and used to document the short and long-term changes of several barrier island systems in Louisiana. Vectorized shorelines, created from the Lidar data, provide an accurate and measurable change in shape, area, and shoreline movement over short and long-term periods.
Are there legal restrictions on access or use of the data?
