What is a "GPS Trace"?
You will often hear editors talking about using a "GPS Trace" to verify roads that don't show up on either the satellite view or street view, or to verify directionality -- but what are they talking about?
Waze records the direction of user travel at routine intervals, and it uses little colored arrows to show those routes in the map editor:
