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 180 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.

set of ASCII fixed record length files. File formats

and data dictionary for the BTS standard format are

described in the document, National Transportation

Atlas Data Dictionary and Database Formats, September

1995. Copies of this documentation are distributed

with each National Transportation Atlas Database.
