Description:

Polygons of submerged aquatic vegetation (SAV) were delineated from photo signatures identified on 4 band orthophotography. Ground truthing was done after initial delineations where completed. Ground truthing was done by boat using underwater video equipment and GPS. Final delineation and GIS database development was done using ground truth information. Over 235 delineations of eelgrass and widgeon grass were made totaling 1386 acres.
