Their vertical datum is NAVD88 (GEOID12A) meters.\nEighty-five DEMs, based on a 2-kilometer (km) by 2-km tiling scheme, cover the entire survey area.\nThese lidar data are available to Federal, State and local governments, emergency-response officials, resource managers, and the general public.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "http://pubs.usgs.gov/ds/0838/", "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.819000f1-7a14-4cd5-bbea-d42e1f0b7636.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_819000f1-7a14-4cd5-bbea-d42e1f0b7636", "keyword": ["Alabama", "Barrier Islands", "Breton Island", "COASTAL PROCESSES > BEACHES", "Chandeleur Islands", "DEM", "DOI/USGS/CMG > COASTAL AND MARINE GEOLOGY, U.S. GEOLOGICAL SURVEY, U.S. DEPARTMENT OF INTERIOR", "Dauphin Island", "Digital Elevation Model", "Grand Gosier Island", "Gulf of Mexico", "Gulf of Mexico Barrier Islands", "LAND SURFACE > TOPOGRAPHY > TERRAIN ELEVATION", "LIDAR", "LIDAR > LIGHT DETECTION AND RANGING", "Louisiana", "OCEAN > COASTAL PROCESSES > BARRIER ISLANDS", "Stake Island", "USGS:819000f1-7a14-4cd5-bbea-d42e1f0b7636", "United States", "altimetry", "bare earth", "bathymetry and elevation", "digital elevation models", "distributions", "elevation data", "hydrology", "laser altimetry", "lidar", "model", "remote sensing", "topographic mapping", "topography"], "modified": "2020-10-13T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-89.207247, 29.465167, -88.030572, 30.289239", "theme": ["geospatial"], "title": "Topographic Lidar Survey of Dauphin Island, Alabama and Chandeleur, Stake, Grand Gosier and Breton Islands, Louisiana, July 12-14, 2013 -- Bare Earth Digital Elevation Models (DEMs)"}
