Geographic Info System (GIS)
We are currently experiencing technical issues affecting our GIS services, including our online parcel viewer. To ensure continued access to property data, we have set up a temporary parcel viewer, which can be accessed here: Union/Snyder County Parcel Viewer.
The GIS contains data layers such as parcels, municipal boundaries, topography, land-use, watersheds, roads, bridges and buildings.
Submit an application to update your property parcel address.
Please visit the Union County GIS Department website for more maps and information on obtaining data, maps, or getting a 911 address.
