Thanks for the map, Kevin, I think it does a great job of combining the data with Google maps and is very useful as a initial guide to finding local dark regions. One suggestion I have...does the US border need to be white? Look in the Washington, DC/Maryland eastern shore area. I know some coastal sites are white areas due to heavy coastal development, but the white boarder makes all coast lines look like Atlantic City.



You must be talking about the 15 color map. That one has state and county borders which I know can get in the way sometimes. I couldn't find a 15 color map without the borders. But the 8 color map has no borders so that might be better for you to use.

Ah, yes...the link I was using was just the 15-color map. Didn't know there was an 8-color version, but I did find it. Thanks!

Sorry I didn't really optimize the website for mobile devices. I don't have an Ipad to test with either. Maybe someday I'll learn how to build an app though.




No need to build an app just use iUI:

For those of you that also like to use the Google Earth overlays, I have made overlays for all of the regions on Earth available from the images at www.lightpollution.it

The overlays can be found here:

@kevin and greg
thanks for the hard work guys. if I am reading it correctly the images are from 1997 or 2001 right? I think there is a new image released by nasa in 2012. I think they even have .kml file for google earth. any hopes of converting that to the .kmz overlays?

I have been using "DarkSky Finder" for several years.

Hi everyone.
I have a project that I have been working on for the past 2 months. My goal was to make the best website for light pollution maps.

DarkSiteFinder.com

I use light pollution data that has been around for awhile but most of it has never been combined with Google Maps before. All the maps on this site are full screen, searchable, and the overlay can be toggled on and off. There is a 15 color light pollution map of the United States from Dave Lorenz that some may find more useful than the 8 color.

Besides the US, light pollution data is now easily viewable for almost any place in the world. The data from the Light Pollution Science and Technology Institute has been available for years but I'm not aware of any other websites that made it all easily viewable.

Also on the site I included some links and information about how to reduce light pollution. I'm planning to have a section that will have an extensive list of observing sites. But that will remain under construction for awhile longer as I try to find a way to integrate some useful features.

Please let me know how you like the website and if you have any suggestions to make it better.

No, they are different kinds of images. The older ones are synthesized images estimating light pollution on the ground. The 2012 one is only an image of light going up into space.

There is so much confusion about the different images, sites, scales, colors, that someone should write a FAQ for this forum's reference and, once it's in good shape, have it pinned at the top or added to the best links sticky.

Often even people giving recommendations or links here, trying to be helpful, do so based on misunderstanding.

Thank Kevin for the maps. This a real help. Any idea how we
might find how dark an observing site might be in county of a particular state? If this could be found we could go there
with some expectations of being good and then report back
to your web site that it was good or just fair.
Show us how we can help.
Again many thanks. You deserve the GOLD STAR AWARD LOL
Thanks De Lorme
