Bonjour. les cartes de pollution lumineuse de cette page ne seront plus mises à jours. Merci d’aller sur les pages de la pollution lumineuse européenne
Hello. light pollution maps on this page will not be updates . Thank you to go to the pages of the EUROPEAN light pollution

Here are the map of light pollution of a part of the United Kingdom.
Some thoughts …
I focused the job on the main island. Ireland is, for the time being, not yet rendered. England, Scotland and Wales are covered by the map of light pollution.
I rendered maps in different folowing ways
A-« Color scale » map
Visual observation light pollution map + topography + relief
Light pollution map + without typo
Map for astrophoto & CCD
B- PDF « Sodium »
Light pollution map + topography + relief (for public demo)
- « Color scale » light pollution map (KMZ file)
- C- Google Earth files
Following recent advances in data management, maps in Google Earth have significantly improved their positioning precision.
Anytime, urbanization datas I have are relatively incomplete, missing some small villages that have _after checking_ urban lighting! So, in rural areas, some sources of light pollution are not on maps. I’m sorry but
right now I have no way to do otherwise.
These maps are absolutely free, however this takes time and required hardware to build them. Any donation will be greatly appreciated (€ , £ or $)
White : 0-15 visible stars (without planets) according to the conditions. Very high level of light pollution and all around. Typical of big urban centre and big regional and national cities.
Magenta: 25-80 visible stars. Principles constellations began to be recognizable.
Red: 80-150 stars : constellations and others stars appears. In a telescope, Some Messier object began to be observable.
Orange: 150-250 stars in good conditions. The light pollution is present all around but some darks areas appears. Typicaly the middle suburbs.
Yellow: 250-500 stars. Strong light pollution but the Milky Way can appear in good conditions. Some Messiers among the most bright can be visible with the necked eye.
Green: 500-1000 stars : far peacefull suburbs, Milky Way many times visible but very sensitive to the atmospheric conditions. Typicaly, the glare of light pollution take a large place in the sky and reach at 40-50° of elevation.
Cyan: 1000-1500 stars. The Milky Way is visible most of the time in fonction of climatic conditions but without contrast.
Blue: 1500-2000 stars. Good sky. The Milky Way is easily visible, we began to have the sensation of a good sky, but, some source of light pollution damage the sky and in a second time the sky by reflexion at the vertical of the observer.
Night blue : 2000-3000 stars. Very good sky. The Milky Way is present and powerfull. The light glares are far away and scaterred, they don’t affect the sky quality.
Black : (green by texture transparency) : more than 3000 stars. No light pollution problems revealable on the sky quality
