Today, I had a reason to go back and look at the Environmental Sensitivity Index maps produced by NOAA. My first encounter with this effort was in the early 80s as part of the review team for Maryland. At the time, I responded to oil and hazardous material spills and these maps provided a wealth of information for our response efforts. We always kept a paper copy in the cab of our response vehicles. This map series has been updated through the years and they are now available in GIS formats. I thought I would pass along some information on how to access these maps for the 28 states and insular areas, and 9 major river basins that have been mapped. You can go to http://response.restoration.noaa.gov/esi to learn more about the maps and to download copies.
