lightpollutionmap.info has recently become useless because advertisements prevent use of the sidebar menus. Anyone know a work-around? I can't close the damned things! Jim (who obsesses about sky brightness, and undertakes research as a citizen scientist)
Try David J Lorenz Light Pollution Atlas. It is updated until 2022. I find it is an excellent resource and even gives the sky brightness readings for individual addresses!
You can import a light pollution layer into Google Earth. It’s just a colour shaded map layer. No interactive click info nor selection of data functions. Just colour shading.
After importing, you need to pull and spread the overlay to match the underlying map. I have not been able to get a perfect match over the whole of Oceania so I just align it for my local region. If I ever want it for another area a long way away, I can just realign it to that area.
