Below is a listing of the attributes found in the three coverages
(_lubc, _astru, and _sstru). The first seven items found in the .aat
files and the first four items in the .pat file are ArcInfo generated.
The item UPLAND with the value of 1 defines the land/water boundary.
FIPS contains the county codes as defined by the Federal government.
FEATURE is land use and contains the following values: 1 = forested,
2 = scrub-shrub, 3 = grass, 4 = residential, 5 = commercial, 6 = bare.
HEIGHT is the bank height with 1 = 0 - 5 feet, 2 = 5 - 10 feet,
and 3 = greater than 10 feet. EROS is the bank erosion condition
where 1 is low erosion and 2 is high erosion. MARSH defines 1 = marsh
eroding, 2 = marsh not eroding, and 3 = no marsh. BEACH defines 1 =
beach eroding, 2 = beach not eroding, and 3 = no beach. An item with a
value of zero means either the structure is not present (as found in
the structure coverage), or that the shoreline in question was not
surveyed (as found in the land use/bank cover coverage). BTHS, DOCK,
and RAMP are present if the value is 1. PTINT contains points of
interest which have been incorporated into the _sstru coverage. BLKHD
(bulkhead), RPRP (riprap), MRNA (marina), GROIN, BREAKWATER, and JETTY
are present with a value of 1.
