Description
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)

Ratings and Reviews
Map is incomplete
Looking through my local area I can see there are landmarks missing, there also seems to be a lack of variance regards differing levels of light pollution… unless the app becomes more reflective of reality I would give it a hard pass.
Developer Response ,
Please report missing landmarks to Microsoft Bing as this app is merely using their base maps. As for light pollution map not reflecting reality (I assume you mean the World Atlas overlay?), I would tend to disagree judging by SQM readings users are submitting, which you can see by turning on the SQM layer. They are well within +/-0.5 magnitude which is the variance of sky brightness due to various atmospheric conditions. You are welcome to send your SQM data for other users to see how wrong the map is.
