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 image 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 McLean County's GIS website.
The McLean County GIS Consortium (members: McLean County, City of Bloomington, and the Town of Normal) provides GIS apps, maps, and data downloads. To view these maps and apps, visit McGIS’s website.
County road maps are available to purchase from the County. Map production requires a fee. For inquiries email the GIS staff or call 309-434-6566.
