A Geographic Information System (GIS) is defined as using different types of geographical data to analyze, visualize, model, digitize, store, and manage information to create maps and reports that can be viewed on a paper map, digital map, or online interactive map.
The goal of the GIS program is to educate the public about McLean County’s activities and projects using maps. To view County GIS maps and apps, visit the County of McLean GIS website.
The McLean County GIS Consortium (members: McLean County, City of Bloomington, and the Town of Normal) provides GIS applications, maps, and data downloads. To view these products, visit the McGIS website.
County road maps are available to purchase from the County. Map production requires an hourly fee. For inquiries email the GIS staff.
