A few months ago an experimental service to automatically find roads and other features in aerial imagery was launched. Today we’re adding to that a service to help improve local search results.

The frontdoor app allows anyone on the web to help improve our address location results. The site allows you to drag a pin from where we think an address currently is to the front door of the property. You do this using our aerial imagery. Not every house is easy to see but many are very obvious.

You are shown random pins to not bias results and multiple people have to move the same pin for the update to happen. As each pin is corrected the data is used to improve local search results as well as help our partners and also it is released to the OpenStreetMap project under the Open Database License.

Feedback is always welcome.
