Welcome to the Illinois GIS Transportation Coalition!
IDOT is taking a leadership role in Illinois government to work towards
developing and maintaining a GIS Transportation framework layer through
the Illinois GIS Transportation Coalition. IDOT envisions the Illinois
GIS Transportation Coalition as being a place to share information
between all levels of government.
The “Intergovernmental Agreement for Sharing NAVTEQ Proprietary Data”
provides the opportunity for interested Illinois governmental agencies
to form geospatial data sharing cooperatives with IDOT. IDOT currently
has over sixty organizations participating in the program. The NAVTEQ
data sharing initiative offers a
roadway coverage that can be used for location analysis, routing, and
other decision support applications for all persons requiring access and
information about the state’s transportation network;
while fostering relationships to further collaborate on changes and
updates to the system. These efforts are working towards establishment
of a single roadway data source that can be used for congestion
mitigation, planning, safety measures, emergency response, and other
transportation related initiatives.

Coalition or obtaining the NAVTEQ data for your agency, please e-mail us
