an explanation for how the images are created:
http://dmsp.ngdc.noaa.gov/html/projects/lights_desc.html

implicit in this image is some similar relation between nighttime
externally-visible light sources and _total_ electric energy use by a given
location.

why the US Defense Meteorological Satelite Program would be interested in
mapping earths' surface light intensity at night is left as an exercise for
the reader.
