Google Map Maker (stylized Google map maker) is a service launched by Google in June 2008, designed to expand the breadth of the service currently offered by Google Maps. In some countries mapping data is unavailable usually[which?] because of Government restrictions on distributing data, and so to fill this void Google has decided to open up Google Maps to a collaborative community effort in certain territories. The ultimate goal of the project is to acquire sufficient high-quality mapping data to be published and used on the existing Google Maps service. Google Map Maker is a separate service than Maps, and changes to Google Map Maker appear on Google Maps only after sufficient review by Google moderators.
