I just wanted to let you know that your voices and concerns are being heard.
Currently because we source all of our map data from NAVTEQ and TeleAtlas,
we may not be able to make manual corrections to your business locations. We
don’t currently have a way for you to submit your specific map corrections
to Google Maps.

Some business owners have reported that adding a note to the “Description”
section of their business listing has helped their customers to find them.

You can edit your listing by following the instructions at

Cheers,

Bill Slawski talks about a recent Google patent to improve location information accuracy. Clearly Google is working on this difficult problem. Obviously, they have yet to solve it.
