The map displays VIIRS/World Atlas/Clouds/Aurora/IAU observatories and the user SQM measurements overlay over Microsoft Bing base layers (road and hybrid Bing maps).
The primary use is to show VIIRS/DMSP data in a friendly manner, but over time it also included some other interesting overlays that concern light pollution like SQM/SQC, World Atlas 2015 zenith brightness, clouds, aurora and IAU observatories. If you have a permanent SQM reader installed you can add it to the map by sending me an e-mail.
If you want an analysis of radiance (VIIRS/DMSP) changes over a period of time, then please use the Lighttrends application (look under Help).
Please send comments and requests for new features via email (look under help)

More usable for mobile
Iβv been using the website for a long time and itβs great to finally have a more usable version for mobile. Happy to support the developer more directly too and remove the ads. Thanks to the developer for adding landscape mode on iPad after request. π Now wishing for a lighttrends app and the new contribution tool π
Great, but wish text was larger.
I really like the app, but I have trouble seeing the text (location names). When i try to zoom, the landscape zooms but the text remains very small. I would love an option to zoom or set the size of the text.
