Guide
Use Google Street View links or embeds to document before-and-after street-level change.
Use nominations when you know a place needs evidence but you do not have the before-and-after links yet.
Add a Google Maps link, a short note, and the location becomes an open lead for contributors.
Approved evidence can be rated from 1 to 5 stars. Ratings build country, region, pin, and user leaderboards.
Signed-in ratings are tied to your account. Anonymous ratings use a local browser identity.
Submissions wait for review before appearing on the public map. Admins can correct labels, years, categories, and coordinates.

Anonymous ratings are tied to a local browser identity, not your account. If you sign in, your submissions and ratings are linked to your profile. We do not sell or share your data with third parties.
We use a session-scoped pseudonymous identifier to measure visits, evidence views, ratings and shares. Analytics are retained for up to 90 days. Global Privacy Control and Do Not Track signals disable this measurement.

To report a specific pin, use the Report this pin button on the pin itself. This sends it directly to the moderation queue.
