The National Elevation Dataset (NED) is a data set that contains bare -earth raster surfaces, maintained at three resolutions: 1 arc - second ( -30m), 113 arc - second ( -10m), and 1/9 arc - second ( -3m). The 1/9 layer coverage is produced from LIDAR data and is available only for selected areas, including North Carolina. NED data can be downloaded from the National Map Seamless Server. http: / /seamless.usgs.Vov/ EPAs Sea Level Rise Publications discuss nationwide impacts of SLR, including beach erosion, floods, estimates of future sea level rise, and threats to coastal wetlands. http: / /www.epa.gov /climatechange /effects/ coastal /slrreports.html EPA's Climate Change Program has made available maps all the data underlying the article on Maps Vulnerable to Sea Level Rise by Titus and Richman (2001). http: / /epa.gov /climatechange /effects /coastal/ slrmaps GIS.html These data, as well the EPA coastal data used to create the elevation maps published in a February 2008 draft report on sea level rise, are also available at http: / /maps.risinVsea.net /data.html. Titus, J. G. and C. Richman. 2001. Maps of lands vulnerable to sea level rise: modeled elevations along the US Atlantic and Gulf coasts. Climate Research 18:205 -228. Jim Titus has also produced Sea Level Rise Planning Maps showing which lands would be protected from sea level rise given existing policies. The draft EPA report is summarized in the Titus et al. 2009. North Carolina specific information, including a report by Clark et al. (20 10) can be found at http: / /plan.risingsea.net /North Carolina.html The data set used to create these maps in this report is available from: http : / /risingsea.net /ERL /data.html Clark, W., J Kassakian, and J.G.Titus. 2010.

Environmental Research Letters 4:044008. Woods Hole Science Center completed a National Assessment of Coastal Vulnerability to Sea -Level Rise in 2000. This project, within the USGS Coastal and Marine Geology Program's National Assessment, used a coastal vulnerability index (CVI) to determine the relative risks due to future sea -level rise for the U.S. Atlantic, Pacific, and Gulf of Mexico coasts. The CVI quantifies the relative risk that physical changes will occur as sea level rises based on the following criteria: tidal range, wave height, coastal slope, shoreline change, geomorphology, and historical rate or relative sea level rise.
