The subject file represents the Arkansas portion of the The National Waterway Network, a comprehensive network database of the nation's navigable waterways. The nominal scale of the data set 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. U.S. Army Corps of Engineers Navigable Waterway Network, version 2.2, 1998. 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. The scale varies due to varying source data.", "summary": "The National Waterway Network is a geographic database of navigable waterways in and around the United States, for analytical studies of waterway performance,...", "title": "NAVIGABLE WATERWAYS 1998 (line)", "tags": [ "Arkansas", "rivers", "inlandWaters", "United States", "river" ], "type": "", "typeKeywords": [], "thumbnail": "", "url": "", "minScale": 0, "maxScale": 0, "spatialReference": "", "accessInformation": "", "licenseInfo": "None.
