Samenvatting
The DVD 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 decisionmaking 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. (Author/publisher)
