We exist to provide maintenance of and access to Cook County's enterprise geographic information system (GIS), including related hardware, software, applications, program development and training. The department provides shared geographic-based information via a network that facilitates secure access where required.
GIS is used by Cook County agencies that need to track, display or correlate information to a geographic locale. GIS data is also made available through data sharing agreements to municipalities that maintain their own independent GIS environments.
GIS services primarily focus on the creation and maintenance of the land base, or data specific to documenting features on the earth. This includes cadastral, or property information, which, along with aerial imagery, forms the base of most maps and analyses. The County GIS Department delivers a high-quality, current geographic computing platform that supports the County's many location-based operations and services.

In compliance with an ordinance passed June 4, 2002, by the Cook County Board of Commissioners, a Geographic Information System (GIS) fund was created to be used for the equipment, personnel, materials, and necessary expenses incurred in implementing and maintaining an enterprise Cook County geographic information system. The special fund is administered by the Cook County Bureau of Technology. Policies and priorities are determined by a multi-agency Geographic Information Systems Steering Committee consisting of representatives from all the land-based agencies within Cook County.
