I'm rather surprised that even North Korea is mapped quite extensively in OSM.(https://mvexel.github.io/thenandnow/#14/38.9911/125.7365).
For a long time, North Korea was shown as a featureless area in google maps.

I wonder if some of this data - both on OSM and Google Maps - was from defectors and military sources.
I don't really know much about NK, but I can't help thinking their regime wouldn't be too happy if their citizens gallivanted around with GPS devices and uploaded POIs to western internet services.
