Google Maps shows North Korean gulags, streets

SEOUL, South Korea - Google Inc.'s map with more details of North Korea has gone live.

Google Maps shows details of North Korea, including streets, parks, monuments and train stops in the capital of Pyongyang. Until Tuesday, North Korea was among the few places in Google Maps where scant information was available.

The map shows at least four places where North Korea's government is believed to operate prison camps.

Google says citizen cartographers started building the North Korea map in 2009 based on satellite images and other public information.

It also shows photographs of places in North Korea available on the Web and those taken by people who visited there.

The U.S. company said the map is not perfect and building the map is an ongoing process.
