A simple comparison between the 1848 U.S. Coastal and Geodetic Survey T-Sheet #243 map (left) and the 2006 U.S. Department of Agriculture (USDA) National Agriculture Imagery Product (right) for the Grand Bay region located at the border of Mississippi and Alabama. A digitized surface/shoreline from the 1848 survey is presented in red and overlain onto the National Agriculture Imagery Program (NAIP) image to highlight the extensive estuarine marsh-wetland area loss.
