The wetland and back-barrier shorelines of New Jersey's barrier islands 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. Making 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. This 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's barrier islands that were extracted from orthoimagery (orthoaerial photography) dated from March 9, 1991 to July 30, 2013. This data set consists of lines that were digitized at the intersection of the back-island shoreline and a set of transects spaced at 20-meter (m) intervals. The transects, nj_transects_ln_20m_utm18.shp, are included in this Data Series publication and can be accessed via the Data Download page, located at http://pubs.usgs.gov/ds/0960/_ds_data-products.html. The lines falling between the transects do not follow the natural back-island shoreline. Only one back-island shoreline/transect intersection line vector was digitized per transect. Orthoimagery 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). The following list provides additional details about the orthoimagery used. The digitized back-island shorelines are organized by area (Sandy Hook, Barnegat Bay, Great Bay, Ludlum Bay, Great Channel, and Cape May) with all dates for each area compiled into one data-set (shapefile) named bshrln__.shp. The orthoimage date for each line is included in the shapefile attribute table "Date" field.

Purpose: These data were extracted from orthoimagery to document the changes in the undeveloped barrier island areas of New Jersey's back-island shoreline due to Hurricane Sandy and over time since 1991. These data will aid in developing an assessment of the physical change in wetlands due to wave action and storm surge from Hurricane Sandy and in determining the resiliency of wetland systems that protect adjacent habitat and communities.

Use_Constraints: Variability in the quality of the imagery from one date to another, from one image to another taken on the same date, and from one part of an image to another part of the same image, exists due to many factors including variation in sun angle, atmospheric conditions, season, reflectivity of the earth surface, camera angle, camera lens, camera settings, film sensitivity, water turbidity, water depth, tide level, waves, and error in image rectification. No adjustments were made to account for tide level. Public domain data from the U.S. Government are freely redistributable with proper metadata and source attribution.
