How often does Google Maps update satellite images?

Answer

Google updates Google Maps and Google Earth images whenever new imagery becomes available, and there is no set schedule. Most images are one to three years old.

For people who are interested in knowing when maps of certain locations are updated, Google offers an alerting service at followyourworld.appspot.com. Alerts are emailed whenever the satellite or aerial imagery in the user's area of interest is updated. To use this service, users need a Google account.

Google also welcomes input from users. They can report a problem on a map and, with the Google Map Maker, even add or change map information.
