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.
The purpose of this project was to derive mean-high-water shoreline, dune crest (DHIGH) and dune toe (DLOW) elevation for a portion of the Eastern United States coastline following Hurricane Sandy, for use as a management tool and to make these data available to natural-resource managers and research scientists.
Are there legal restrictions on access or use of the data?

|Data format:||LAS; IMG; SHP; ZIP (version 1) The dune features (Post_Sandy_dunes.shp) and mean-high-water shoreline (Post_Sandy_shoreline.shp) are ArcGIS shapefile data compressed into zip files with metadata. The DEM files (ERDAS Imagine) and LAS are compressed into zip files by tile number within their respective state and data folders. The tile index (in ArcGIS shapefile) provides tile naming convention and data download information.|
