How to use the Johnson County viewer
- Open the official link; the map is hosted on TerraGIS, a vendor platform used by 14 counties in our directory.
- Accept any disclaimer, then use the search tool to find a street address, owner or parcel ID.
- Click a parcel to view its attributes.
- Use the layer or basemap controls to add aerials and other layers where the county provides them.
Rural addresses don't always geocode well. When that happens, zoom in by hand and click the parcel, or search by owner name.
