Environmental Sensitivity Index (ESI) Atlas: Alabama, maps and geographic information systems data (NODC Accession 0013800)

This data set comprises the Environmental Sensitivity Index (ESI) maps for the shoreline of Alabama. ESI data characterize coastal environments and wildlife by their sensitivity to spilled oil. The ESI data include information for three main components: shoreline habitats; sensitive biological resources; and human-use resources. This atlas was developed to be utilized within desktop GIS systems and contains GIS files and related D-base files. Associated files include MOSS (Multiple Overlay Statistical System) export files, .PDF maps, and detailed user guides and metadata.

The intertidal habitats were mapped using a combination of aerial photographs taken between 1985 and 1987, and low altitude color video surveys taken in 1992 and 1993. The biological and human-use resources data were compiled by regional biologists in 1995. The dates for these source data vary and range from the mid- 1970s to the mid-1990s. Detailed date information is provided in the included metadata.
