The light pollution map has two base layers (road and hybrid Bing maps), VIIRS/World Atlas/Clouds/Aurora overlays and a point feature overlay (SQM, SQC and Observatories). If you want detailed analysis of radiance (VIIRS/DMSP) changes over a period of time, then please use the Lighttrends web application(not mobile optimised).
The Bortle scale is one measure of determining sky brightness (light pollution) at night. A number of places are protected for their dark skies - these generally are at national and state parks and forests around the world. The DarkSky International vets dark sky locations and are a good place to start in your search for truly dark skies. Bear ...

Nov 15, 2019 · Dark Sky Map contains Google Maps overlays and allows astronomers to search for suitable spots using the satellite view and data from light pollution charts. You can add a spot to the map and a description is automatically populated with an overview of the quality of the sky in that location and ratings from other stargazers.
3 days ago · Read from left to right. Locate a column of blue blocks. That's when the sky will likely to be clear and dark. A more detailed explanation is here, but the short version is: the clear sky chart predicts hourly cloud cover, atmospheric transparency and seeing. (Good "seeing" occurs when the air is steady enough to allow you to see fine detail on ...
