What is GIS?

The WTH GIS Mapping System provides Union County residents, businesses, and property owners with easy online access to important property and geographic information.

Through the interactive mapping platform, users can view parcel boundaries, property lines, aerial imagery, ownership information, tax records, addresses, and other land-related data throughout the county.

The system is designed to help the public quickly locate properties, research parcel information, and better understand county mapping data from any computer or mobile device.
