Description
Abstract: The US Army Corps of Engineers (USACE) Ports
database is an extract from the National Waterway
Network database consisting of 224 points coded as
US Army Corps of Engineers ports.
Purpose: The Ports database is a geographic database of
the US Army Corps of Engineers Ports in and around the
United States, for analytical studies of waterway
performance, for compiling commodity flow statistics,
and for mapping purposes.

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.
Positional Accuracy
Horizontal Positional Accuracy
Horizontal Positional Accuracy Report: The accuracy of
each point element is correlated to the data source
used to derive that element. For example, links and
nodes derived from 1:100,000 scale Digital Line
Graphs are more accurate than links and nodes
derived from 1:500,000 scale NOAA Navigational
Charts. Elements with an "M" in the source field
(indicating an unknown or missing source) are the
least accurate.
