Friday, October 25, 2019 - The Fall 2019 update to the National Transportation Atlas Database (NTAD) was released today with three new datasets and 10 updated datasets.

NTAD is a Bureau of Transportation Statistics (BTS) compilation of geospatial datasets representing the nation’s transportation infrastructure, containing roadways, railways, waterways, and airports.

The three new datasets in this version are the National Tunnel Inventory, Time Zones, and the Dockless Bikeshare and E-scooters. For more information on the Time Zone layer, please see the story found here.

Additional updates in this release include:

• Airport data including:
  • Airports (Facilities)
  • Runways
  • Runway Ends;

• Passenger Intermodal Facility (IPCD);

• Bikeshare;

• Congressional Districts with newly appointed Members of Congress;

• Alternative Fueling Stations;

• Rail data including:
  • North American Rail Network Lines
  • North American Rail Network Nodes;

• National Parks

NTAD is available for download in comma separated values (CSV), Keyhole Markup Language (KML), and shapefile formats through the BTS Geospatial Data Catalog. Additionally, Open Geospatial Consortium (OGC) standard Web Feature Services (WFS) (including Web Mapping Services (WMS)) are available for all NTAD datasets. Also available are optimized services that allow for fast rendering of full NTAD datasets, and vector tile services for 13 of the largest NTAD datasets. These full NTAD datasets and their respective faster services are designated by service names ending in “DS” for each layer, and the vector tiles service names ending in “VT”.

BTS now uses a dynamic NTAD publication cycle, making updated data available throughout the year when they become available from their respective government agencies.
