Maryland Archived Submerged Aquatic Vegetation - SAV 1998

The Chesapeake Bay SAV was mapped from 1:24,000 black and white aerial photography to assess 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.
