The 2002 Chesapeake Bay Submerged Aquatic Vegetation (SAV) was mapped from 1:24,000 black and white aerial photography to access water quality in the Bay. Each area of SAV was interpreted from the rectified photography and classified into one of four density classes by the percentage of cover. This is a MD iMAP hosted service.
