The wetland and back-barrier shorelines of New Jersey changed as a result of wave action and storm surge that occurred during Hurricane Sandy, which made landfall on October 29, 2012.  The impact of Hurricane Sandy will be assessed and placed in its historical context to understand the future vulnerability of wetland systems.\nMaking these assessments will rely on data extracted from current and historical resources such as maps, aerial photographs, satellite imagery, and lidar elevation data, which document physical changes over time.\nThis USGS Data Series publication includes several open-ocean shorelines, back-island shorelines, back-island shoreline points, sand area polygons, and sand lines for the undeveloped areas of New Jersey that were extracted from orthoimagery (ortho aerial photography) dated from March 9, 1991 to July 30, 2013.\nThis data-set consists of lines that comprise the inland extent of the main body of sand (beach/dune/overwash area) found in the orthoimagery taken on the date specified in the filename and in the \"Date_\" field in the feature attribute table.  They are based on the sand area polygons, nj_sandpo_*.shp, that are included in this Data Series publication and can be accessed via the Data Download page.\nOrthoimagery of New Jersey were acquired in digital format from U.S. Department of Agriculture (USDA), U.S. Geological Survey (USGS), National Oceanic and Atmospheric Administration (NOAA), and New Jersey Geographic Information Network (NJGIN).\nThe following list provides additional details about the orthoimagery used.  The sand lines are organized by area with all dates for each area compiled into one data-set (shapefile) named nj_sandln_<range of dates>_<area name>.shp.  The orthoimage date for each line is included in the shapefile attribute table \"Date_\" field.\nDate\t\t\t\tType\t\tSource\t\tResolution\n19910309-19910313\tPan\t\tUSGS, DOQQ\t\t1 m (meter)\n19950325-19950407\tCIR\t\tUSGS, DOQQ\t\t1 m\n20020218-20020411\tCIR\t\tNJGIN\t\t\t1 m*\n20060805-20060613\tNatural\tUSDA, NAIP\t\t1 m\n20070318-20070415\tNatural\tNJGIN\t\t\t1 m*\n20080808-20080826\tNatural\tUSDA, NAIP\t\t1 m\n20100703-20100726\tNatural\tUSDA, NAIP\t\t1 m\n20120314-20120416\tRGBI\t\tNJGIN\t\t\t1 m*\n20130707-20130730\tNatural\tUSDA, NAIP\t\t1 m\nPan - Panchromatic (1 band, gray scale)\nCIR - Color Infrared (infrared, red, green)\nNatural - Natural Color (red, green, blue)\nRGBI - Natural Color and Infrared (red, green, blue, and infrared)\nDOQQ\t- Digital Orthophoto Quarter Quads\nNAIP\t- National Agriculture Imagery Program\n*Resampled from 1-foot resolution imagery then smoothed using a 3 m by 3 m focal mean.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://pubs.usgs.gov/ds/0960/downloads/cape_may.zip", "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.f9f93cc6-bd67-4ce7-b403-c16733a53964.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_f9f93cc6-bd67-4ce7-b403-c16733a53964", "keyword": ["1991", "1995", "2002", "2006", "2007", "2008", "2010", "2012", "2013", "Atlantic County", "Barnegat Bay", "COASTAL PROCESSES > BEACHES", "Cape May", "Cape May County", "DOI/USGS/CMG > COASTAL AND MARINE GEOLOGY, U.S. GEOLOGICAL SURVEY, U.S. DEPARTMENT OF INTERIOR", "Great Bay", "Great Channel", "LAND SURFACE > LAND USE/LAND COVER > LAND COVER", "Ludlum Bay", "Monmouth County", "National Seashore", "New Jersey", "OCEAN > COASTAL PROCESSES > BARRIER ISLANDS", "Ocean County", "Sandy Hook", "USGS:f9f93cc6-bd67-4ce7-b403-c16733a53964", "United States", "aerial photography", "beach", "erosion", "orthoimagery", "orthophotography", "overwash", "remote sensing", "sand"], "modified": "2020-10-13T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-74.905369, 38.928692, -73.973971, 40.482178", "theme": ["geospatial"], "title": "Sand Lines for the Undeveloped Areas of New Jersey's Barrier Islands, Extracted from Orthoimagery, March 9, 1991, to July 30, 2013"}
