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.

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.
