With over 600,000 sites actively using the Google Maps API, more people around the world view maps provided by the Maps API than any other source. For this reason it’s vitally important that Google Maps provides the most accurate and up to date map data possible. For this reason we're happy to introduce updated maps and the "Report a Problem" tool to France, Luxembourg, and Monaco.
As with previous updates in countries such as the U.S.A., Australia, and parts of Europe, this update utilizes a wide range of authoritative sources such as the Institut Geographique National. In addition, the "Report a Problem" tool on Google Maps allows you to let us know if some aspect of the map that needs correcting, and we'll do our best to address it quickly (often within just a few days).
These map updates will roll out over the next 24 hours across all our Maps APIs and related services. As with previous updates we do ask that you refresh any data that you have previously obtained for these countries using Maps API Web Services, and cached for use in your Maps API application. If you have any questions or concerns relating to this, please post them to the Google Maps API forums.
