Below is a listing of the attributes found in the three coverages
(_lubc, _sstru, and _astru). The first seven items found in the .aat
files and the first four items in the .pat file are ArcInfo generated.
Stmco_lubc contains the following items; FEATURE or land use, has the
following values: ' ' = no data, forest, scrub-shrub, grass, bare
residential, paved, commercial, agriculture, and military. HEIGHT is
bank height with 0 or ' ' = no data, 0 - 5 feet, 5 - 10 feet, 10 - 30
feet, and greater than 30 feet. COVER describes the bank cover with
values of 0 or ' ' = no data, bare or less than 25% covered,
partial coverage (25-75% coverage), and full coverage (greater than
75% coverage). EROSION is the bank erosion condition. Values can
be 0 or ' ' for no data, low erosion, high erosion, or undercut.
MARSH provides information on the status of the marsh; 0 or ' ' = no
data, marsh eroding, marsh not eroding, and no marsh. BEACH
defines 0 or ' ' = no data, beach eroding, beach not eroding,
and no beach. REMOTE refers to how the data was gathered: a blank
value or an "n" indicates the data was collected with the GPS unit in
the field, a "y" indicates that the shoreline attributes where
determined from the DOQQ imagery. However, an empty REMOTE value
along with other empty values indicates no data was collected. PHRAG
with the value 'yes' indicates the presence of phragmites. STRUCTURE
contains the types of shoreline structures found in Dorchester County:
bulkhead, riprap, breakwater, miscellaneous (bricks, timbers, concrete
blocks, tires, etc.), groin field, and marina. PNTSTRUC
