Google Maps has included cartographic information of North Korea without any help from the country.
People interested in the country were asked to add in street names, buildings, landmarks and work camps.
Curtis Melvin from the John Hopkins School of Advanced Studies has been creating a digital atlas of North Korea but was not involved in the project.
He told BBC Radio 5 live Up All Night what he made of the Google version.
