Title: Detailed study of Google Maps zoom levels
Post by: 1 on September 21, 2013, 10:53:10 PM
Detailed map of Google Maps road levels from zoomed out to in. These levels have always existed, but some looked exactly like others.

Dead end: Dead ends, some exceptions.
White: Normal road.
Yellow: Road that used to be yellow (and is yellow in Google Mapmaker)
Route: Has a route number; there are some false negatives and false positives though.
Orange: Obviously light orange. Almost all US routes are at least this.
Thick orange: Used to look like a freeway, but looks like normal orange except in 2 specific zoom levels.
Freeway: Dark orange.

So what happens when a road shows up on one zoom and disappears on the next one?

If you are talking about what NH 125 does (shown at zoom level 7 or more, but only partially at exactly 9), zoom level 9 is probably the worst zoom level out of all of them.
