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

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

  1. Hi Frederic,

    I am the chairman of the Thanet Astronomy Group.
    We are a group that specialises in bringing astronomy to beginners in plain English.
    We are based in (Thanet) North East Kent, England.
    We have been looking for maps of this detail for some time.
    We would like to include your maps on a dedicated page on our web site.
    Would we be able to do this ?
    How would you like it to be done ?


  2. Hi ,
    Its possible to get the map for INDIA..?

  3. As an amateur astronomer in the UK this is EXACTLY what I’ve been looking for, a thousand thankyou’s!

    I am an MSc student studying Countryside and Protected Area Management. As part of my dissertation I am involved in a local community partnership who are writing a planning document to protect a river estuary (the Deben Estuary) in Suffolk. My responsibility is to use GIS to generate maps for issues such as important bird areas, mammal records, wildlife sites, flood risk and, amongst others, light pollution. I have been using MAPINFO and Ordnance Survey data to do this, but am very keen on using your Light pollution map with Google Earth as one of the maps.

    Is it possible to receive permission to use your software to generate a map on light pollution. Obviously I will reference you as the source at the bottom of the map.

  4. Hi,
    I have to say this is a very interesting article about light pollution!
    I always wondered why we couldn’t see stars from some places and we had thousands in others!
    Do you think you could make a light pollution map also for France??
    It would be very instructive!
    Thanks alot for all thoses informations and keep up the good work!

  5. Salut,

    Puis-je avoir la permission d’utiliser la carte du Royaume-Uni La pollution lumineuse pour un plan d’affaires. Je l’ai trouvé sur votre websire. Je souhaite l’utiliser pour fournir un appui pour mon idée.

    Merci beaucoup pour votre temps et asisstance

  1. […] When out in the field i use on my iphone : Moon free. This is a phase app and rise set and age app from your vey coordinates by the min incase i need to see how long ive got of dark skies Sun rise set app : really good for precise rise set duration times The two astronomy planning apps i use are : Sky harbinger mainly for atmosphere and cloud cover Clear outside is my second choice as its layout for twilight dark times and moonrise are good , cloud seeing pickering etc is clear .
