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.
FEATURE is land use and contains the following values: 0 = no data,
1 = forested, 2 = scrub-shrub, 3 = grass, 4 = residential,
5 = commercial, 6 = bare, and 10 = agriculture. HEIGHT is the bank
height with 0 = no data, 1 = 0 - 5 feet, 2 = 5 - 10 feet, and 3 =
greater than 10 feet. COVER describes the bank cover where 0 = no data,
1 = bare or less than 25% covered, 2 = partial coverage (25-75%
coverage), and 3 = full coverage (greater than 75% coverage). EROS is
the bank erosion condition where 0 is no data, 1 is low erosion
and 2 is high erosion. MARSH defines 0 = no data, 1 = marsh eroding,
2 = marsh not eroding, and 3 = no marsh. BEACH defines 0 = no data,
1 = beach eroding, 2 = beach not eroding, and 3 = no beach. REMOTE
refers to how the data was gathered: a blank value 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.
COUNTY indicates the county name (aprroximately 3 miles of
Northumberland shoreline is included with the Lancaster data). BTHS
(boathouse), and DOCK are present if the value is 1. RAMP (boat ramp)
is present with a value greater than 0, where 1 = private ramp and
2 = public ramp. PTINT contains points of interest which have been
incorporated into the _sstru coverage. BLKHD (bulkhead), RPRP (riprap),
MRNA (marina), GROIN (groin field), JETTY, and BREAKWATER are present
with a value of 1.
