A “Light Pollution Map”

www.lightpollutionmap.info is a mapping application that displays VIIRS/DMSP/World Atlas overlays/IAU observatories and the user 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 deal with light pollution like SQM/SQC, World Atlas 2015 zenith brigtness and IAU observatories. If you have a permanent SQM reader installed you can add it to the map by contacting me.

Annual VIIRS comparisons are to be avoided as there are too many factors involved by just doing a direct comparison. If you want an analysis of radiance (VIIRS/DMSP) changes over a period of time, then please use the Lighttrends application.

Data for observatories sourced from Wikipedia. If you want to contribute to the list, you can do so by editing this document
