Geographic Information Systems (GIS) Mapping

Union County GIS Search  

The County Auditor oversees and coordinates the County's GIS mapping program. In conjunction with the County Engineer, orthophotos are shot and overlayed on a master map of Union County. These maps clearly depict buildings, land characteristics and uses, property lines, soil types, hydrography, and hundreds of additional bits of information about the County.    M.A.P.S.    is a GIS tool which enables you to view parcel map information, parcel boundaries, aerial photography as well as political boundaries.

For the other Auditor Property Search tools and resources, please visit the Property Search Tools page where you can find links to the basic and advanced Parcel search, Subdivision/Plat search, GIS data and other real estate files in downloadable formats, and the county's historical tax Maps. Â
