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.
Lidar data were acquired to document the short and long-term changes of several barrier island systems in Louisiana. Digitized shorelines created from the Lidar data provide an accurate and measurable change in shape, area, and shoreline movement over short and long-term periods. Lidar elevations can provide a measurable change in the topography of barrier island systems to track pre- and post- storm elevation changes.
Are there legal restrictions on access or use of the data?
