Guide
Compare dated views, rate the evidence and add a place.
Suggest a location when you do not have both dated Street View links.
Add a Google Maps link, a short note, and the location becomes an open lead for contributors.
Choose No decline, Mild decline, Clear decline or Severe decline. Rate only the visible change supported by the two dated views.
Top rated pins need at least three ratings. Community ratings are opinions about the submitted evidence, not an official measure of an area.
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.
Add DeclineMap to your home screen and open it in its own window.
Maps and Street View need an internet connection.
