How to use the Yates County viewer

  1. Click the button above and wait for the Web AppBuilder viewer to load. Some counties show a terms screen first.
  2. Search by street address, owner or parcel ID if the search box offers those options.
  3. Click a lot on the map to read its attributes.
  4. Turn on aerial imagery from the basemap tool and use the layer list to add things like zoning or flood zones when they're published.

Rural addresses don't always geocode well. When that happens, zoom in by hand and click the parcel, or search by owner name.

Maps vs. surveys

The lines you see online are approximate. They're good for finding a lot and its parcel number, but a legal boundary question needs the recorded plat or a surveyor.
