Abstract: The National Transportation Atlas Databases, 1996 (NTAD96) is a set of national geographic databases of transportation facilities. These databases include geospacial information for transportation modal networks and intermodal terminals, and related attribute information. These databases are most useful at the national level. They do not provide explicit connections between modes and terminals. The NTAD96 CD-ROM is designed for use within a geographic information system (GIS). However, the files are in ASCII format and can be ported to any database, spreadsheet or other software package. The contents are organized into a series of subdirectories, one for each feature type (point, line, and polygon), and one for each database. The transportation networks are line database. Transportation terminals exists as point databases. The geographic reference files exist as all three types: point, line and polygon databases. POINT directory arranges information into various files: AIRPORT-public use airports-landing facilities in the U.S., 1995; TOFC-trailer on flat care and container on flat car highway/rail transfer terminal, 1995; AMTK_STA-Amtrak stations/railway terminals, 1995; PORT-water ports and facilities, 1995; PLACE-place name point file from 1980 census master area reference file; AUTORAMP-highway/rail transfer facilities which contains auto loading ramps. Network information for national highway, railway, waterway, runway can be found under LINE directory. Polygon data for states, counties, 104th congressional districts, national parks, federal adjusted urbanized areas, MSA, BEA economic areas and national transportation analysis regions are stored under POLYGON directory.
