Our services
Find out how our design office can help you analyze lighting and light source data, understand the light pollution issues associated with your project or area, and guide your decision-making.
Data acquisition
Automated, continuous photometric measurements of night sky quality from the ground
Low or very high resolution satellite or aerial night imagery
Field surveys (technical characteristics of lighting points, photographic surveys, etc.)
Get to know our tools and methodsStatistical and cartographic analysis
Continuous evolution of night sky quality, analyzed using photometric meas-urements
Technical indicators for diagnosing and monitoring lighting systems, based on known characteristics of lighting points.
Localization of light sources and detection of lighting practices, using satellite or aerial night images
Explorer nos technologiesModeling light pollution
Mapping diffuse light pollution, i.e. the brightness level of the night sky
Mapping of direct light pollution, i.e. the level of exposure to lighting fluxes

Browse our solutionsOur main areas of expertise
Lighting park performance
we help public and private-sector professionals to improve their installations and practices, in order to optimize the services provided to the population while reducing negative impacts and costs.
Preserving biodiversity
we support "dark ecological network" projects (connected ecological areas to be spared from artificial light) and studies aimed at reducing the harmful ef-fects of light pollution on species.
Protection of the dark sky and astronomical observation
we support local authorities in their efforts to maintain or restore the visibility of the stars, particularly in the context of applications for the "International Dark Sky Reserve" label.
Emerging applications
reducing human health nuisances, monitoring and managing safety issues (road accidents, delinquency and crime), journalistic investigations, etc.
Do you have a project in mind?
You can use certain functions of our tools on our online software platform,
or entrust your work and analyses to our engineering department.
We'll be there to support you either way.
