Democracy on the Front Lines

GIS stands for Geographical Information Systems and is used to place layers of information on digital maps and the City of O’Fallon has been using GIS digital mapping for several years. I am pleased to announce that City GIS maps are now online on our web site for your enjoyment.
When you go to the home page, you can click on the “City Maps” button on left side of the page (or click here). The web site will automatically open into the O’Fallon map. To view different features, click on the Globe icon and there will be a list of layers to place on the map. Here are the different kinds of information you can find in each area:
- Public Works: water, sewer, and stormsewer systems
- Historical Aerials: photos of O’Fallon from various moments in the past
- Parks and Public Safety: parks, street trees, fire districts, fire hydrants, and storm sirens
- Planning and Economic Development: ward boundaries, ZIP code boundaries, state legislative boundaries, school boundaries, and zoning boundaries.
You can also zoom in and out of the map and conduct searches on specific addresses. The GIS provide a wealth of information and it is fun to look at the different layers, particularly the historical aerial photographs.
One thing you cannot do on our GIS map is to view property values and tax data. That information is owned by St. Clair County and you can click here to search properties by last name, address, or parcel number.
