Development is on the rise despite the fact that coastal infrastructure is subjected to flooding and erosion.  As a result, there is an increased demand for accurate information regarding past and present shoreline changes.  To meet these national needs, the Coastal and Marine Geology Program of the U.S. Geological Survey (USGS) is compiling existing reliable historical shoreline data along open-ocean sandy shores of the conterminous United States and parts of Alaska and Hawaii under the National Assessment of Shoreline Change project.\nThere is no widely accepted standard for analyzing shoreline change.  Existing shoreline data measurements and rate calculation methods vary from study to study and prevent combining results into state-wide or regional assessments.  The impetus behind the National Assessment project was to develop a standardized method of measuring changes in shoreline position that is consistent from coast to coast.  The goal was to facilitate the process of periodically and systematically updating the results in an internally consistent manner.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/F74X55X7", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.58b89052e4b01ccd5500c295.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_58b89052e4b01ccd5500c295", "keyword": ["Wassaw Island", "United States", "Shoreline", "Woods Hole Coastal and Marine Science Center", "Cumberland Island", "Digital Shoreline Analysis System", "Transect", "St Catherines Island", "Historic Shoreline", "Sapelo Island", "Savannah River", "North America", "Coastal and Marine Geology Program", "U.S. Geological Survey", "WHCMSC", "Atlantic Coast", "USGS", "coastal processes", "CMGP", "Erosion", "USGS:58b89052e4b01ccd5500c295", "GA", "National Assessment of Shoreline Change Project", "environment", "DSAS", "Linear Regression Rate", "Jekyll Island", "Accretion", "Sea Island", "oceans", "Long-Term Shoreline Change Rate", "geoscientificInformation", "effects of coastal change", "erosion", "Tybee Island", "shoreline erosion", "shoreline accretion", "Georgia"], "modified": "2024-03-19T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-81.488728, 30.712390, -80.833780, 32.026364", "theme": ["geospatial"], "title": "Digital Shoreline Analysis System version 4.3 Transects with Long-Term Linear Regression Rate Calculations for Georgia (GA)"}
