The distribution of submerged aquatic vegetation during 1987 in the Chesapeake Bay, its tributaries, and Chincoteague Bay was mapped at a scale of 1:24,000 using color aerial photography. Submerged aquatic vegetation bed perimeter information was digitized and stored in a computerized data base. Ground truth information was obtained from the U.S. Geological Survey, the Maryland Department of Natural Resources, the University of Maryland Horn Point Laboratory, Harford Community College and the Virginia Institute of Marine Science. Citizen support via the U.S. Fish and Wildlife Service and Chesapeake Bay Foundation, as well as the Maryland Charterboat Association via the Maryland DNR Watermen's Assistance Program, provided additional ground truth information.
