  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.

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: RITA/BTS quality checks were to cross reference the dataset with the state dataset to determine if the spatial data and attribute data were accurate within each state

      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 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.
