Google Maps shows North Korean prisons, streets

The map of the North Korean capital offers more details than other parts of the country, including the names of streets and the location of the square named after the country's late founder, Kim Il Sung.

Google Maps also links to photographs taken in North Korea. Many of these photos show streets and buildings of Pyongyang taken by visitors while some photos are from North-Korea focused websites, such as NKeconWatch.com.

The rest of the country remains mostly blank but some airports, highways, universities and major streets are marked.

The map also marks at least four places where North Korea's government is suspected of operating prison camps.

An Myung-chul, who heads a nonprofit organization called Free the NK Gulag in Seoul that gathers information from former North Korean prisoners, said Google Maps' information on North's prison camps are "mostly accurate" although a concentration camp near Kaechon should be farther south.

The group said it believes there were five prison camps in North Korea before one was shut down in mid-2012 based on its analysis of satellite images and testimonies from former prisoners.
