In case you you want to prepare yourself for the upcoming comet "Nishimura" or other celestial events 🌝
I knew about the high levels of light pollution in the Netherlands and Belgium but Moscow is what really surprised me on this map. I never would've expected it to be so high. Looks like it has the highest levels outside of China.
I wanted to add this map as an overlay map in Osmand to find good camping spots for night sky viewing. I have the USGS land management data as an overlay, and wanted both. Never got around to it, but now maybe I will. I see there's an OSM version of this map, I wonder if I could just download it and load it in?
I haven't worked with OSM data before, but you can take a look at the source of the website.
Very nice! But I had a weird problem after opening it for the first time on mobile (solved forcing the desktop view) and it's missing a legend to know what colours represent, especially when selecting the 2014-2020 trend.
