Friday, July 15, 2011 - The U.S. Department of Transportation's Bureau of Transportation Statistics (BTS), a part of the Research and Innovative Technology Administration, released the 2011 edition of the National Transportation Atlas Databases (NTAD) this week. 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. Also, substantial revisions were made to national parks, waterways, railways and the Federal Highway Administration's National Bridge Inventory. This year's NTAD consists of 32datasets, 11 of which were updated for this 2011 release. The NTAD also includes: intermodal terminals, national railway crossings, non-attainment areas and transit rail lines and stations, among other data layers. NTAD 2011 is provided in shapefile format, which is compatible with most Geographical Information Systems (GIS) software
