I was working on a little neighborhood near me this afternoon. This one right here
The problem with it was that the little cul-de-sacs were named correctly but incorrectly placed. Chelsea Ct, for instance, went right through that house next to Rollingwood Dr and Falmouth Ct was also displaced and not shaped correctly.
To help fix it I used Bing maps which did have the correct, or close, configuration but I needed to go back and forth between the two to get the streets realigned.
What I'd love to have is a Bing Overlay layer that shows the current Bing streets at the same zoom to help with alignment. In this case the Bing map was a Wintertime aerial view and the trees didn't mask the streets as much. This made it much easier to see the problems and solutions. Bing maps aren't the absolute authority but they can provide guidance; having an overlay would save having to pop back and forth between the two maps.
I've run into this a few times now and thought I'd see if I could get it "on the list" ...
