Reviewers may also reach out to the business or organization associated with the reported location to confirm its accuracy.
Once a review is complete, the reviewers will make a determination about the accuracy of the reported location. If the location is found to be accurate, it will remain on the map. If the location is found to be inaccurate, it will be removed from the map or moved to a more accurate location.
Google also uses an automated system to detect and remove potentially inaccurate map locations. This system uses a variety of factors to identify potentially inaccurate locations, including:
* The number of user reports against the location
* The consistency of the location across different sources
* The location's proximity to other businesses or organizations
If the automated system identifies a potentially inaccurate location, it will be flagged for review by a human reviewer.
Google is committed to providing the most accurate and up-to-date map data possible. The company encourages users to report any inaccurate map locations that they find. Users can report inaccurate map locations by:
* Clicking on the "Report a problem" link on the map
* Submitting a feedback form through the Google Maps help center
* Tweeting to @GoogleMaps with the #MapIssues hashtag
