Geographic Information

The Geographic Information Program office at the Research and Innovative Technology Administration’s (RITA) Bureau of Transportation Statistics (BTS) is a national resource for transportation spatial data and analysis that utilizes Geographic Information Systems (GIS). GIS enhancement allows planners and others to visualize large quantities of transportation data, often rendering it more meaningful. GIS helps highlight the transportation system's reach, coverage, modal relationships, key corridors, and relationship to our nation's economic activity and environment.

Recent Changes

Recently a number of changes have been made on the availability of services offered by the Geographic Information Program and are reflected on this website. The following programs, previously offered by the Geographic Information Program, Web Mapping Service applications for viewing and data downloading, the Mapping Center, and External GIS site links have been removed. Other federal Web Mapping Services can be found at www.geodata.gov. While these were beneficial to the Transportation community and the U.S. DOT, budgetary constraints have forced these to be suspended as the administration reprioritizes all RITA programs. Other programs, including the National Transportation Atlas Database (NTAD) and operation of the Federal Geographic Data Committee (FGDC) Transportation Subcommittee will continue.

Activities

National Transportation Atlas Database (NTAD)
NTAD 2007 is complete and available for download only. You can also request an NTAD CD through the BTS Bookstore. If you have any questions about the NTAD please call Mark Bradford at 202-366-6810.

Geospatial One Stop
The Geospatial One Stop is a federal government E-Gov initiative that will create, among other things, an Internet portal for data discovery and exchange. Standards development efforts have been concluded and all Geospatial One Stop standards are now undergoing American National Standards Institute (ANSI) review.

FGDC Transportation Subcommittee
The latest developments and activities of the FGDC Transportation Subcommittee are available.
