USER NOTES:

The National Waterway Network is a geographic database of navigable waterways in and around the UnitedStates, for analytical studies of waterway performance, forcompiling commodity flow statistics, and for mappingpurposes.

Links in the waterway networkrepresent actual shipping lanes or serve as representative paths in open water where no definedshipping lanes exist. Nodes may represent physicalentities such as river confluence's, ports/facilities, and intermodal terminals, US Army Corps of Engineers (USACE nodes), or may be inserted for analytical purposes.

Merging of inland and offshore waterway networks required a specialized program written to merge the two networks. In general, Vanderbilt nodelocations were accepted as authoritative when both datasets had the same elements. This meant moving an OakRidge link incident to that node. If the link wasclassified geographically ocean or Great Lakes, and aVanderbilt link or chain existed with the same ID andendpoints, the Oak Ridge link was discarded, aftertransfer of Oak Ridge attributes. If the Oak Ridge linkwas within 2 km of the new end nodes' location: and 1)if a duplicate Vanderbilt link existed with a highersource code, it replace the Oak Ridge link, or 2) theOak Ridge link was moved by a logistic adjustment to the new location. (This causes modest disruption to thepreponderance of the shape, yet assured that the angleof approach to the displaced end node location waspreserved.) 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 addedat the end to snap to the new node location withoutdisrupting the original link shape. If the link had aVanderbilt duplicate with the same ID, the Oak Ridgelink was so flagged to be manually resolved. Thecomposite network was then cleaned manually, resolvingall cases of still remaining duplicate links and deciding case-by-case how to smooth or otherwiseaccommodate a highly displaced Oak Ridge shape into theVanderbilt digitized node location, using TIGERshorelines as a background.

DATA LINEAGE SUMMARY:

The National Waterway Network was created onbehalf of the Bureau of Transportation Statistics, the U.S. Army Corps of Engineers, the U.S. Bureau of Census, and theU.S. Coast Guard by Vanderbilt University and Oak RidgeNational Laboratory. Additional agencies with input into network development include Volpe National Transportation Systems Center, Maritime Administration, Military TrafficManagement Command, Tennessee Valley Authority, U.S.Environmental Protection Agency, and the Federal RailroadAdministration.

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.
