Google has puts its first detailed maps online of North Korea, a country that has so far been mostly blank on the search giant's popular Maps website.

The data was compiled on Google's Map Maker tool, which allows users to contribute information mainly using satellite images or local knowledge.

Many landmarks are now labelled, as are notorious prison labour camps and nuclear research sites.
