USDOT/FHWA GIS Applications

HEPGIS

The HEPGIS website is an interactive, web-based geographic map server that enables users to navigate, view, and print geospatial maps using only their web browser.

AEGIST

The Applications of Enterprise GIS for Transportation (AEGIST) Guidebook shows how agencies at all levels of government can work together to develop a consistent means of collecting, maintaining, and publishing spatial data.

National Transportation Noise Map

The U.S. Department of Transportation’s Bureau of Transportation Statistics’ (BTS) initial National Transportation Noise Map shows that more than 97 percent of the U.S. population has the potential to be exposed to noise from aviation and Interstate highways at levels below 50 decibels or roughly comparable to the noise level of a humming refrigerator.
