Welcome to the online home of the Department of Geographic Information Systems in Will County, Illinois. The mission of the department is to coordinate and provide GIS services to many GIS professionals and hundreds of regular and casual GIS users from county departments and agencies. We also support many local governments on their GIS efforts and coordinate GIS projects with federal, state, and local agencies outside Will County. And last, but not the least, we are here to serve county residents and the general public on their needs of spatial information relevant to their work and their daily life.

This newly redesigned web site is a part of our efforts to enhance the quality of our services to the GIS professionals and users, the residents and the general public. Here you can find useful information that includes maps, data, and online applications. We are constantly improving our work. So if you have any suggestions and comments, feel free to send them to gis@willcountyillinois.com. Enjoy your web surfing.
