Below is a listing of the attributes found in the three shapefiles
(_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.
Chowan_lubc contains the following items; FEATURE or land use, has the
following values: ' ' = no data, Agriculture, Bare, Commercial, Forest,
Grass, Industrial, Paved, Residential, Scrub-shrub, and Swamp. Height
is bank height with ' ' = no data, 0 - 5 feet, 5 - 10 feet,
10 - 30 feet, and greater than 30 feet. COVER describes the bank
cover with values of ' ' = 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 ' ' for no data, low erosion, high
erosion, or undercut. MARSH provides information on the status of
the marsh; ' ' = no data, Yes(Erosion) = marsh eroding,
Yes(No_Erosion) = marsh not eroding, and No = no marsh. FRINGE_MAR
is a narrow strip of marsh vegetation extending along the shoreline.
If it is present this item is coded 'yes', otherwise it is 'no' or ' '.
BEACH defines ' ' = no data, Yes(Erosion) = beach eroding,
Yes(No_Erosion) = beach not eroding, and No = no beach. PHRAG with
the value 'yes' indicates the presence of Phragmites australis.
TREE_FRING with the value 'yes' indicates there are a narrow bnad of
trees growing on the bank. STRUCTURE contains the types of shoreline
structures found in the Chowan River: bulkhead, riprap, debris (tires,
bricks, etc. tossed haphazardly along the shoreline), unconventional
(concrete blocks, or other miscellaneous material placed neatly along
the shoreline for stabilization), groin field, jetty, dilapidated
bulkhead, and marina (<50 slips, or >50 slips). PNTSTRUC
contains the types of access structures or points of interest found
along the shoreline: docks/piers, boathouses, public and private
ramps, outfalls (pipes open to the water), and other points of
interest. GPS_DATE holds the date of data collection.
