    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 dataset 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.

    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 "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_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 as 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.
