Apparently Google Maps isn't the only the only service to run into trouble with a foreign government, having a large scale map will do it as well. Forbes.com has an article about how Russia considers large scale maps to be state secrets.
While Google Maps has recently drawn the ire of several countries, including India and the the Netherlands for its maps of sensitive areas, Russia is going old school and suspending BP's operations over the handling of large scale maps. Apparently, in Russia maps with a 1:25,000 scale are too detailed for the eyes of foreigners and can get you arrested for possessing State Secrets. This incident as well as the Google maps incidents highlight the importance of Cartography. Namely that levels of detail on maps are extremely important in todays world whether it be for oil reserves or military installations.
