Purpose: This dataset was compiled by the GIS program of the Geological Survey of Alabama in support of the "Comprehensive GIS Inventory in Coastal Alabama" as funded by the National Oceanic and Atmospheric Administration(NOAA) through the Coastal Impact Assistance Program.

If the user has modified the data in any way they are obligated to describe the types of modifications they have performed on the hardcopy map. User specifically agrees not to misrepresent these data sets, nor to imply that changes they made were approved by Geological Survey of Alabama (GSA). The GSA should be acknowledged as the originator of the data. This data set is to be used as a primary reference source. This is public information and may be interpreted by organizations, agencies, units of government, or others based on needs; however, they are responsible for the appropriate application. Federal, State, or local regulatory bodies are not to reassign to the originators any authority for the decisions they make. Photographic or digital enlargement of these maps to scales greater than that at which they were originally delineated can cause misrepresentation of the data. If enlarged, the maps will not include the fine detail that would be appropriate for mapping at the large scale. Digital data files are periodically updated. Files are dated, and users are responsible for obtaining the latest version of the data. Boundaries of polygons extending into the water (ocean or Great Lakes) should be considered arbitrary.

After, the .dxf was converted from .dxf into a .shp format, unprojected from UTM Zone 16W NAD27 into geographic clarke 1866 Decimal Degrees, NAD27. Topology was built to calculate perimeter and area. Other attributes were added as described below.
