These Geographic Information Systems (GIS) datasets from the U.S. Geological Survey (USGS) can be used to determine projected sea level rise for the coastlines of the United States. They are stored in an attribute table associated with a 1:2,000,000 shoreline at 3-minute resolution. Thus, for each 3-minute (approx. 5 km) section of shoreline, there are data for each of the following variables: geomorphology, relative rate of sea-level rise, coastal slope, mean wave height, tidal range and erosion and accretion rates, as well as their ranked values (1-5) and the calculated coastal vulnerability index (CVI). The datasets are available on CD as ArcView shape files and Arc export files which can be used with ArcExplorer, a free GIS viewing software available from ESRI. They can also be downloaded as ZIP files.
