India
at night, satellite view. This image is a composite showing the change in
illumination over India from 1992-2003. Satellite data from 2003 is coloured
red, 1998 is coloured green and 1992 is blue. The three data sets are
composited to form the image. Nighttime lights on the map that are white are
lights that were present throughout the entire period. Areas that are marked by
red have only appeared in 2003. Areas coloured green and blue were only present
in 1998 and 1992 respectively but are no longer visible.
