How to use the Marinette County viewer
- Open the official link in a new tab.
- Accept any disclaimer, then look for a search box that takes street addresses, owners or parcel IDs.
- Zoom in and click a parcel to see its details.
- Use the map's layer controls to add aerials or other layers if they're offered.
Rural addresses don't always geocode well. When that happens, zoom in by hand and click the parcel, or search by owner name.
