Description
Abstract: The National Waterway Network is a comprehensive
network database of the nation's navigable waterways.
The data set covers the 48 contiguous States plus the
District of Columbia, Hawaii, Alaska, Puerto Rico and
water links between. The nominal scale of the data
set varies with the source material. The majority of
the information is at 1:100,000 with larger scales used
in harbor/bay/port areas and smaller scales used in open
waters.
Purpose: The National Waterway Network is a geographic
database of navigable waterways in and around the United
States, for analytical studies of waterway performance, for
compiling commodity flow statistics, and for mapping
purposes.
Supplemental Information: Links in the waterway network
represent actual shipping lanes or serve as
representative paths in open water where no defined
shipping lanes exist. Nodes may represent physical
entities such as river confluences, ports/facilities,
and intermodal terminals, US Army Corps of Engineers
(USACE nodes), or may be inserted for analytical
purposes.
Approximately 224 USACE ports are geo-coded in the node
database.

Data Set Credit: The National Waterway Network was created on
behalf of the Bureau of Transportation Statistics, the U.S.
Army Corps of Engineers, the U.S. Bureau of Census, and the
U.S. Coast Guard by Vanderbilt University and Oak Ridge
National Laboratory. Additional agencies with input into
network development include Volpe National Transportation
Systems Center, Maritime Administration, Military Traffic
Management Command, Tennessee Valley Authority, U.S.
Environmental Protection Agency, and the Federal Railroad
Administration.
DATA QUALITY INFORMATION
Attribute Accuracy
Attribute Accuracy Report: Attribute accuracy is tested by
manual comparison of the source with hard copy printouts
and/or symbolized display of digital line graphs on
an interactive computer graphic system; selected
attributes that cannot be visually verified on plots
or on screen, are interactively queried and verified on
screen.
Logical Consistency Report:
Completeness Report:
Positional Accuracy
Horizontal Positional Accuracy
Horizontal Positional Accuracy Report: The "shape
source" field in the link database, and the "node
source" field in the node database indicate the data
sources used to derive link and node placements. The
accuracy of each network element is correlated to the
data source used to derive that element. For example,
links and nodes derived from 1:100,000 scale DLGs are
more accurate than links and nodes derived from
1:500,000 scale NOAA Navigational Charts. Links with
unknown/missing sources are usually schematic
representations of USACE links.
Off-Shore: NOAA Charts vary in scale. Larger scale
charts were used in harbor/port areas, while smaller
scale charts were used in open water. For channels,
sea lanes, and Intracoastal Waterways, shape points
were placed as needed to ensure that link segments
fall within waterway boundaries.
Inland: Links digitized from 1:100,000 DLG files, or
large scale NOAA charts are the most accurate
representations. Shape points were placed as needed
to ensure that link segments fall between waterway
shorelines. Links derived from Corps milepoints
have shape points approximately one mile apart. The
Corps milepoints were mainly derived from 1:24,000
and 1:100,000 scale maps. Therefore, the shape
points derived from Corps milepoints are often as
accurate as shape points derived from 1:100,000 DLG
files. However, line segments connecting the shape
points may not accurately represent the curvature of
the waterway.

Process Step
Process Description: Merging of inland and offshore
waterway networks. A specialized program was written to
merge the two networks. In general, Vanderbilt node
locations were accepted as authoritative when both data
sets had the same elements. This meant moving an Oak
Ridge link incident to that node. If the link was
classified geographically ocean or Great Lakes, and a
Vanderbilt link or chain existed with the same ID and
endpoints, the Oak Ridge link was discarded, after
transfer of Oak Ridge attributes. If the Oak Ridge link
was within 2 km of the new end nodes' location: and 1)
if a duplicate Vanderbilt link existed with a higher
source code, it replace the Oak Ridge link, or 2) the
Oak Ridge link was moved by a logistic adjustment to the
new location. (This causes modest disruption to the
preponderance of the shape, yet assured that the angle
of approach to the displaced end node location was
preserved.) If the link was functionally classed "deep
draft" and a duplicate Vanderbilt link had an
authoritative source code, the Oak Ridge link was
replaced. Otherwise an additional shape point was added
at the end to snap to the new node location without
disrupting the original link shape. If the link had a
Vanderbilt duplicate with the same ID, the Oak Ridge
link was so flagged to be manually resolved. The
composite network was then cleaned manually, resolving
all cases of still remaining duplicate links and
deciding case-by-case how to smooth or otherwise
accommodate a highly displaced Oak Ridge shape into the
Vanderbilt digitized node location, using TIGER
shorelines as a background.
