Geographic Information System

The Franklin County Auditor's appraisal Geographic Information System (GIS) is a computer graphics and mapping program comprised of more than 4,000 color aerial photographs, site photography and property records. The system, which has received national recognition, consists of geographic data layers attached to a base map.

Data layers include property lines, planimetric features (aboveground structures), and topographic details (land contours, elevations and hydrography), as well as other factors that affect property values.

The GIS Section provides additional services, including public-access computer terminals in the Auditor's map room on the 19th floor of the Franklin County Courthouse, 373 S. High St. In 1995, the GIS Section began producing quarterly releases of the GIS base map on DVD's in three formats: MetaMAP, DXF and Shapefiles.

Since January 1996, all updated property information has been recorded only in the GIS. Prior to 1996, information was recorded on approximately 3,800 paper tax maps that had been in existence for 150 years.
