National Transportation Atlas Database Winter 2020 Update

Friday, January 24, 2020

Friday, January 24, 2020 - The Winter 2020 update to the National Transportation Atlas Database (NTAD) was released today with one new dataset and 11 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 new dataset is the Inland Electronic Navigational Charts (IENC) data, found here.


Additional updates in this release include:


  • Passenger Intermodal Facility (IPCD);


  • Bikeshare;


  • E-Scooters and Dockless Bikes;


  • Fatality Analysis Reporting System (FARS) with 2018 values;


  • Congressional Districts with newly appointed Members of Congress;


  • Alternative Fueling Stations;


  • US Army Corps waterway data including:
    • Ports
    • Major Ports;


  • Maritime Administration data including:
    • Marine Highways
    • Strategic Ports;


  • National Parks


The traffic fatalities map is an example of an analysis that can be performed using the newly-updated FARS database.


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.
