I found the map of greenland fascinating, since there is pitch black internally. Everything is along the coast.

At the lowest zoom level what are geometric lines that criss cross Greenland and the curvilinear lines and rings off the coasts?

Do you mean like this one:

That's just territorial waters.

The lines across Greenland are administrative borders:

I guess there is so little mapped there that they can stand out.

Another interesting note: I would have expected North Korea to be dark, but it's brighter than neighboring China.

And South Korea is not nearly as bright as its population and wealth suggests.
