Applications in GIS
State and Local Applications
This web page is a gateway to numerous GIS transportation applications currently being employed across the nation.
Each application in the State and Local GIS Practices Index provides the following information: GIS practice title, "subject area" of Federal Highway Administration (FHWA) responsibility, state, city, contact information, and a brief description of the practice. Contact information is provided so that you may directly contact your colleagues and learn more about the ways they are implementing GIS in transportation activities. Additional State DOT contacts who work in GIS are available on the GIS-T website.
This page offers two methods for retrieving GIS practice information. Use the Map to retrieve all practices for a state or the Search Engine to find specific practices.
If you would like to submit a practice for database inclusion review or have additional information about a particular GIS application, please report back to us.
Search Using the Map
To retrieve all transportation GIS practices for a state, click on the map or on the state list.
To narrow your search, use the search engine below.
Search transportation GIS practices by any combination of the following options: keyword, state, city, and/or category.
USDOT/FHWA GIS Applications
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.
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.
