[sac-forum] Re: Dark Sky Maps

The World Atlas of Arificial Night Sky Brightness is here:

http://www.lightpollution.it/worldatlas/pages/fig1.htm


From there, you can find the map of North America, and unzip the 2 Mb file (to 
130 Mb!).  It is a very high-resolution file when you're done.

Or, for regional coverage, you can go to the Clear Sky Clock site at 
http://cleardarksky.com/csk/ and click on the light pollution map link for the 
area in which you are interested.
