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.
Pg_lubc contains the following items; FEATURE or land use, has the
following values: ' ' = no data, Agriculture, Bare, Commercial, Forest,
Grass, Industrial, Paved, Residential, and Scrub-shrub. 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, Yes(Erosion) = marsh eroding,
Yes(No_Erosion) = marsh not eroding, and No = no marsh. BEACH
defines 0 or ' ' = 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.
STRUCTURE contains the types of shoreline structures found in
Prince George's County: bulkhead, riprap, debri (tires, bricks, etc.
tossed haphazardly along the shoreline), unconventional
(concrete blocks, or other miscellaneous material placed neatly along
the shoreline for stabilization), 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.
