Abstract
The National Waterway Network is comprised of a link database and a node database. Links are line strings, which consist of beginning and end points (nodes) with intermediate vertices (shape points). Links represent either actual shipping lanes (i.e., channels, Intracoastal Waterways, sealanes, rivers) or serve as representative paths in open water (where no defined shipping paths exist).
Tonnage is summarized for each link by commodity and direction (up bound and down bound). The commodities include: Coal | Petroleum Products | Chemicals | Crude Materials | Manufactured Goods | Farm Products | Machinery | Waste | Unknow

Mode
Water
