Light Pollution Atlas

The Light Pollution Science and Technology Institute has produced what it calls a World Atlas of Light Pollution
. The website is not so much an atlas but a patchwork collection of maps derived from satellite data indicating various measures of light pollution. Lengthy explanations are offered for the 7 different maps
but perhaps that best and easiest to understand map is the world map of artificial night sky brightness
. The map is an incomplete incomplete picture of the world (some northern areas are missing) and comes in a variety of sizes and extents. Other maps, such as the total night sky brightness map
, focus on a specific part of the world. All of the maps could benefit from a graphic legend instead of a written (e.g. “white indicates . . .” or “green indicates . . .”) one.
