The NWN 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, sea lanes, rivers) or serve as representative paths in open water (where no defined shipping paths exist). Nodes may represent physical entities such as river confluence's, ports/facilities, and intermodal terminals, USACE nodes, or may be inserted for analytical purposes (i.e., to facilitate routing).</span></p></div></div></div></div>\", \"distribution\": [{\"@type\": \"dcat:Distribution\", \"accessURL\": \"https://geospatial-usace.opendata.arcgis.com/maps/ace7645d305647448a84492a3b909d48\", \"format\": \"Web Page\", \"mediaType\": \"text/html\", \"title\": \"ArcGIS Hub Dataset\"}, {\"@type\": \"dcat:Distribution\", \"accessURL\": \"https://services7.arcgis.com/n1YM8pTrFmm7L4hs/arcgis/rest/services/Waterway_Networks/FeatureServer\", \"format\": \"ArcGIS GeoServices REST API\", \"mediaType\": \"application/json\", \"title\": \"ArcGIS GeoService\"}], \"identifier\": \"https://www.arcgis.com/home/item.html?id=ace7645d305647448a84492a3b909d48\", \"issued\": \"2024-10-25T17:57:06.000Z\", \"keyword\": [\"geospatial\", \"inland waters\", \"oceans\", \"transportation\"], \"landingPage\": \"https://geospatial-usace.opendata.arcgis.com/maps/ace7645d305647448a84492a3b909d48\", \"license\": \"<div style='text-align:Left;'><div><div><div style='font-size:12pt;'><p>Links in the waterway network represent actual shipping lanes or serve as representative paths in open water where no defined shipping lanes exist.
