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.

       Format Information Content: The BTS standard format for
          spatial data is an interim format for distributing
          National Transportation Atlas Databases pending final
          approval of an SDTS Transportation Network Profile
          (TNP).  The BTS standard format consists of a linked
          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.
