Geographic databases for 2011 released

Posted 15 July 2011, by Staff, Commercial Carrier Journal (CCJ), ccjdigital.com

The U.S. Department of Transportation’s Bureau of Transportation Statistics, a part of the Research and Innovative Technology Administration, has released the 2011 edition of the National Transportation Atlas Databases. NTAD 2011 is provided in shapefile format, which is compatible with most Geographical Information Systems (GIS) software.

The 2011 edition features updated datasets from last year’s NTAD and premieres the Customs and Border Protection’s border crossing database with data spatially enhanced by BTS. Substantial revisions also were made to national parks, waterways, railways and the Federal Highway Administration’s national bridge inventory.

This year’s NTAD consists of 32 datasets, 11 of which were updated for this 2011 release. The NTAD also includes intermodal terminals, national railway crossings, nonattainment areas and transit rail lines and stations, among other data layers.
