National Transportation Atlas Database

The National Transportation Atlas Databases 2011 (NTAD2011) is a set of nationwide geographic databases of transportation facilities, transportation networks, and associated infrastructure. These datasets include spatial information for transportation modal networks and intermodal terminals, as well as the related attribute information for these features. Metadata documentation, as prescribed by the Federal Geographic Data Committee, is also provided for each database. The data on this DVD support research, analysis, and decision-making across all modes of transportation. They are most useful at the national level, but have major applications at regional, State, and local scales throughout the transportation community. NTAD2011 is organized into subdirectories, one for each feature type (point, polyline, and polygon) and one for each database. At the top level of the DVD, there is also a doc’s subdirectory containing the back cover notes and these liner notes. Also at the top level of the DVD there is a pdf version of the BTS 2011 map of Major Transportation Facilities of the United States. This map showcases many of the data contained in NTAD2011. Transportation networks are polyline databases. Transportation facilities are point databases. The geographic reference databases may exist as any of the three feature types: point, polyline, or polygon.
