Thanks to “Dark skies”
Thanks to 17,000 volunteers we have already classified the first 130,000 pictures using the app Dark skies. Check all the cities in a map.
You can choose any of these images from the map and try to identify the city with Lost at night application.

Once nocturnal images are identified we are locating them all. Thanks to the image metadata we know where the ISS was located when the picture was taken so know the city should be in a 500 km area around the ISS nadir. With that approximation our volunteers have located more than 2500 images: City gallery
You can choose any of the images and try to geo-reference it with Night cities application.

One we know the city location, we need a georeferencing process. After this process the image is linked to a physical map. We have more than 1000 geo-referenced images on top of the map:
Unfortunately Google Maps Engine stopped working on January 2016 so the map is unavailable at the moment.
