Other Open Data

Certain categories of data (railroads, hydrology features, etc.,) are not maintained by Kendall County GIS, and therefore, are not offered on our Open Data site. Kendall County GIS Open Data is restricted to those layers which are both actively and authoritatively maintained by the department.

Users who wish to acquire reference layers not on our Open Data site may still find this information elsewhere from numerous sources.
