How often does google maps update?

How do I update street information for Google Maps?

• As the result of the end of some works, a street has changed its direction of travel. Is there any way I can notify Google of the change?

• Answer:

  In the bottom right corner of the map, you'll see a tiny link: . This will bring up the Report A Problem dialog. More information can be found http://maps.google.com/support/bin/answer.py?answer=162873&hl=en (it's the Learn More link in the dialog). EDIT: Here is a page with a bit more information with other links and ways to edit information: http://maps.google.com/support/bin/answer.py?hl=en&answer=98014 If this still doesn't work, the map provider is always listed at the bottom of the map. Chances are good that they will have their own way for submitting corrections. You'd need to identify the provider and then do a search.
