NOS Environmental Sensitivity Index (ESI)
NOAA's Environmental Sensitivity Index (ESI) "systematically compiles information in standard formats for coastal shoreline sensitivity, biological resources, and human-use resources. ESI maps are useful for identifying sensitive resources before a spill occurs so that protection priorities can be established and cleanup strategies designed in advance."
The ESI maps are available for North Carolina in GIS data formats (geodatabase, shapefiles, .dbf, and .e00) or as PDF maps. The GIS data and maps are available on the Libraries' Geodata server, CD-ROM, or on the Web via the NOS Data Explorer or the Office of Response and Restoration's website. As of February 2009, the date stamp for the latest North Carolina data online is 1996. Other states have more recent data, however.
