About this app

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

Ratings and reviews

Need to allow choosing SD card or other location for offline cache download. Also adding locations to favorites list ("My Locations") just doesn't work. Nothing happens when you try to type the name, or hit the pin button, or anything. Also can't even see the entire map legend, the legend image is too long to fit on the the screen and it's not possible to scroll down to see the rest of it.

Best app about light pollution. I have been using the web based version since 2017 and so far its the most accurate since I have been to various darksky sites after using it. Is it possible to extract data in csv format from it? Also I can't seem to click on Circle tool for drawing roi why?

Great App! All the important light pollution data in one map with numerous, very useful overlay controls.👏 Thanks for including all my SQM data from Unihedron as well 🙌

What’s new

- Feature filters can be now be saved (settings). Name field also supports wildcard searching for example '*town OR john*' will display 'Smalltown' and 'Johnstown'.
- 'My locations' can now be saved (and edited) and restored from a file.
- 'My locations' now also available as a feature overlay, so you can view them on the map.
- Changing dates in the calendar widget doesn't open virtual keyboard anymore (except when you tap on hour/minute fields).
- Other minor changes and bug fixes.
