A Geographic Information System (GIS) integrates computer technology for collecting, managing, analyzing, and displaying all kinds of spatially referenced information. The information is arranged in data layers. For example, there is an address point layer, and a road line layer, and a parcel polygon layer, etc. A GIS can be searched to find specific locations or browsed to reveal tabular data attached to a particular area of interest.

The County’s GIS is developed and maintained within the Public Works Department. GIS products are used for viewing and analysis for many other departments including the Commissioners Officer, the Elections Office, the Assessor’s Office, the Sheriff’s Department, County Planning and Zoning, the Fire Department, Parks and Recreation, as well as others.
