Friday, July 28 2017 - The U.S. Department of Transportation’s Bureau of Transportation Statistics has released the Summer 2017 update to the National Transportation Atlas Database (NTAD). The NTAD is a compilation of geospatial data sets representing the nation’s transportation infrastructure, containing roadways, railways, and airports. Reference boundary files from other government agencies are also included. In this new update, the rail network data set has added 24 additional features, or 46 more miles. A total of 19,765 airports (an increase of 238 facilities from the last release), and other aviation facilities, are included, with enplanement and passenger data for the large airports. Incorporated in this update are 163 more water ports relative to the last release, totaling 23,598, as well as docks, marinas, and other port facility types. The NTAD, including newly updated data sets, are available for download in Excel, Keyhole Markup Language (KML), and shapefile formats, through the BTS geospatial data catalog. Additionally, Open Geospatial Consortium (OGC) standard Web Feature Services (WFS) are available for most NTAD data sets. BTS now uses a dynamic NTAD publication cycle, making updated data available throughout the year when they become available from their respective government agencies.
