Guide

How it works

Use Google Street View links or embeds to document before-and-after street-level change.

Submit evidence

  1. Open Google Maps Street View and choose the earlier year.
  2. Use Share, copy link, or embed map. Embeds are preferred.
  3. Repeat for the later year from the same place.
  4. Paste both links, choose a category, add the years, and send it for moderation.

Nominate a place

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.

Rating decline

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.

Moderation

Submissions wait for review before appearing on the public map. Admins can correct labels, years, categories, and coordinates.
