Also known as photopollution, is the presence of anthropogenic light in the night environment. It is exacerbated by excessive, misdirected or obtrusive uses of light, but even carefully used light fundamentally alters natural conditions. As a major side-effect of urbanization, it is blamed for compromising health, disrupting ecosystems and spoiling aesthetic environments.

The alteration of the natural quantity of light in the night environment due to the introduction of artificial light is a true pollution. “Pollution” means “impairment of the purity of the environment”. Light pollution stands for “pollution of the light”: pollution of the natural light due to manmade light.

Depending on the kind of map, the map is accounting for many details like the scattering of light by molecules and aerosols, the extinction along light paths, the atmospheric aerosol content, the Earth curvature, the altitude of each area, the mountain screening, the observed sky direction, the natural sky brightness, the stellar extinction, the eye capability…
