Light Pollution Map

The map displays VIIRS/World Atlas/Clouds/Aurora/IAU observatories and the user SQM measurements.

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.
