Light Pollution Map

Light Pollution Map is an interactive tool that uses satellite (VIIRS) data to visualize artificial light pollution across the globe. Click anywhere on the map to see the Bortle Scale rating and Sky Quality Meter reading for that location, and find the nearest dark sky sites for better stargazing. It also includes aurora probability forecasts, meteor shower planning, moon phase and golden hour info, weather overlays, and sky photo analysis. It's built for stargazers, astrophotographers, casual astronomy fans, dark sky advocates, and urban planners who want to understand or reduce light pollution in their area.
