Light pollution map

Light Pollution Map helps you easily find the darkest places nearby by combining high-resolution VIIRS satellite data with an interactive global map. Explore sky brightness, compare light pollution levels, and plan the perfect dark-sky trip or astrophotography session. Whether you’re an astronomer, astrophotographer, stargazer, traveler, or simply curious about night sky quality, this map gives you access to the most accurate and up-to-date night-time light data available. Key Features • Interactive light pollution map with VIIRS (Black Marble 2.0) satellite radiance • Accurate sky brightness and dark sky map overlays (with color blind option) • Various mapping tools (point/area info, moon info, brightness simulation, find closest dark site, VIIRS country stats, adding your own SQM measurements, etc...) • MPSAS (magnitude per square arc second) and Bortle scale estimation for easy comparison • Switch between multiple light pollution datasets • Global coverage with high detail • Additional layers such as Aurora (with prediction), Clouds, user submitted SQM, etc... • Offline-friendly — (World Atlas 2015 can be cached) • Find dark sky locations for astronomy, camping & astrophotography • Compare historical VIIRS data and track how light pollution changes • Intuitive, fast map with smooth controls and fullscreen mode • Clean, privacy-respecting design (no ads, no tracking) VIIRS Satellite Data The app uses NASA VIIRS Day/Night Band data — the same scientific dataset used by research institutions and environmental agencies for monitoring night-time brightness. This ensures maximum accuracy when evaluating artificial sky glow. Find Dark Sky Locations Quickly identify dark places for: • Astrophotography • Stargazing • Camping trips • Milky Way observations • Meteor shower watching • Light pollution research • Aurora spotting Why This App? Light Pollution Map offers a clear, easy-to-read view of global sky brightness without ads or unnecessary features. It focuses purely on delivering the most accurate light pollution map possible — ideal for both hobbyists and professionals. No subscription or other hidden fees. Once you buy it, you have it for life with any update that follows.
