GIS (Geographic Information Systems) is a collection of computer hardware, software, and geographic data for capturing, managing, analyzing, and displaying all forms of geographically referenced information. Boone County's GIS department uses everything from census data to recorded surveys and aerial photos to create a graphical representation of the county. These representations give the County a better idea of conditions and increase the speed and integrity of decisions. For more information about GIS, visit the National Geographic Society's GIS page

The Boone County GIS is a valuable tool used throughout all of the county offices for varying tasks including: planning and zoning, land assessment, property ownership, 9-1-1 call mapping, crime tracking, utilities, infrastructure, road assessment, and many other applications.

The Boone County Assessor and Auditor started development of the GIS in 1999. It was originally installed on three computers. Since that time it has expanded to be used by most County departments.

Boone County's GIS, valuation and tax data are available to the general public via our GIS Beacon website. 

 Boone County GIS data in shapefile format is available as a free download from the Iowa GIS Data Repository (create a logion to access data in the repository). For printing, mailing, and other GIS services please see the Boone County GIS Data & Pricing Policy.
