A while back, I made it so that PadMapper would start showing listings whose locations it wasn’t confident in with a different color marker (grayish-red rather than the normal bright red). I think the variety of colors may have been a bit much for the first-time user, since it wasn’t really clear what the difference was (unless you noticed the pattern of the low accuracy warnings on the info bubbles only appearing for those pale red ones). Also, those had a tendency to stack, since a lot of the vague addresses (57th st, NY, NY for example) would resolve to the same spot on the street.
As such, I’ve made it possible to filter the low quality addresses out, and that filter is on by default. You can uncheck the “Accurately Located” filter to show the low quality ones again.
