About the GeoData Catalog

Welcome to the Kendall County Open GeoData Catalog!

Who are we?

We are the Geographic Information Services (GIS) Department for Kendall County, Illinois.

What is this?

We firmly believe in open data. We believe that when authoritative sources share their data with the community, all parties stand to benefit.

A key part of this is how the data is shared. This site is our attempt at making this process as simple and easy as possible.

How do you use this?

We like to think it’s pretty intuitive, but from the home page, you can find two tables of all our open data layers. One for vector data (points, lines, polygons), another for raster data (basemaps, imagery).

Finding Data

In each table, there’s a search bar you can use to filter the table by its layer name or subtitle.

To the right, you can see a list of categories. Selecting any item from the category list will also filter the tables.

For a broader search, there is a magnifying glass in the top bar of the site. This will search the full text of the entire site.

Catalog Entries

If you just want the file, every entry has download options linked right from the home page. You may also click on the layer name to view a full page of additional information about the layer.

Other Sources

Don’t see what you’re looking for? Here is a list of other data sources you should check out.

Source	Description
Illinois Geospatial Data Clearinghouse	All kinds of physical geography layers, reference information, and the State’s repository of high-resolution elevation data.
OpenStreetMap	Obviously, we already package a lot of OSM data here for our region, but there’s so much more you can pull from the raw data.

Stale Downloads

While we strive to update our downloadable files regularly, the very nature of static downloadable files means they are out of date as soon as they are generated. It is highly recommended that you use the Live Data link instead.

If you genuinely need a file, but also need the most current data, you can open the service URL in desktop GIS software like QGIS and export to the file format of your choice.
