How to use the Delaware County viewer
- Press the button above. The map opens in Esri's ArcGIS Map Viewer in a new tab.
- Type an address or place name into the search box at the top, or drag and zoom the map yourself.
- Click inside a parcel outline. A pop-up lists whatever attributes the publisher shares, such as a parcel ID or acreage.
- Open the Layers panel to hide or show parcels, and use the Basemap button to switch to aerial imagery.
Rural addresses don't always geocode well. When that happens, zoom in by hand and click the parcel, or search by owner name.

Keep in mind that a GIS parcel layer is a tax map, not a survey. For exact boundaries, look at the recorded deed and plat or hire a licensed land surveyor.
