| Background Information | |
Sample Map The Nighttime Lights of North America map layer is an image showing lights from cities, towns, industrial sites, gas flares, and temporary events, such as fires. Most of the detected features are lights from cities and towns. The map layer was derived from cloud-free parts of images taken in 1996 and 1997, during 231 orbits by a Department of Defense satellite. This satellite has a unique ability to detect low levels of visible radiance at night. Further information is available through the Defense Meteorological Satellite Program page. |
