See accuracy report. Quantitative Attribute Accuracy 2022-06-01T00:00:00 See accuracy report. 1 BTS quality checks were completed to cross reference the dataset with the state dataset to determine if the spatial data and attribute data were accurate within each state See consistency report. Conceptual Consistency 2022-06-01T00:00:00 See consistency report. 1 The "shape source" field in the link database indicates the data sources used to derive link 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. See accuracy report.

The US Army Corps of Engineers National Waterway Network (NWN) data was downloaded from https://usace.contentdm.oclc.org/digital/collection/p16021coll2/id/3799. Portions of this polyline dataset that do not appear to represent waterways but rather appear to be projection-related were removed from the data. Then only lines from the NWN data with a FUNC_CLASS value of "S", "B", or "D" were retained for the CNW data; these are the lines considered by PHMSA to be "commercially navigable". All other lines were removed. 2019-12-01T00:00:00 external 479cdc3934f49c3537d2f49ea3d1be36 U.S. Department of Transportation (DOT), Pipeline and Hazardous Materials Safety Administration (PHMSA) 1200 New Jersey Ave., S.E.
