I think that this image (http://i.i.com.com/cnwk.1d/i/tim/2011/12/19/northkoreamap_62...) of Korea is the most striking representation of image equality. It is visible from space with the naked eye.

Check out Haiti vs. Dominican Republic too: http://svs.gsfc.nasa.gov/vis/a000000/a002600/a002640/

That is a naked-eye approximating image? Seems unlikely to have that much non-diffused light from city to space.

It looks like a zoom of an image from the project "Earth's City Lights": http://visibleearth.nasa.gov/view.php?id=55167 . In this project, they don't show a real image, but a reconstruction of multiple images to remove the clouds and other problems.

The images that are linked at the bottom of that page (for example http://eoimages.gsfc.nasa.gov/images/imagerecords/55000/5516... ) are incredible interesting. For example you can see your own country and find the big cities and the gaps where there are almost no cities.

It is similar, at least. Here is another one showing South Korea that is taken using a regular camera from the ISS that shows similar light patterns (https://plus.google.com/117789022459699674254/posts). It's hard to see North Korea because of the angle and the clouds.

That link just goes to someone's (yours?) G+ page. I think you wanted to link to this specifically: https://plus.google.com/117789022459699674254/posts/YsnRsCCB...
