The light pollution map has two base layers (road and hybrid Bing maps), VIIRS/World Atlas/Clouds overlays and a point feature overlay (SQM, SQC and Observatories).

If you want a more detailed analysis of radiance (VIIRS/DMSP) changes over a period of time, then please use the Lighttrends application.

For more information view the help.
