GPS tagging in China

Using GPS to survey locations is technically illegal in China.  Foreigners caught doing so may be charged with espionage.  China is a one party dictatorship.  They have lots of laws, but they selectively enforce them depending on the policy of the day.

On the other hand, everyone in China carries a smartphone with a GPS chip.  Taxi drivers depend on it for navigation.  However, foreign web sites may not supply maps without putting in an offset.  That is why Google maps & satellite views do not line up.  Only Chinese sites may supply correct maps, which the government can turn off whenever they wish.

On my last trip to China, I left my GPS tracker on all day.  Actually, it is a Nexus 7 tablet.  Don't ask, don't tell.
