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.
