Using data provided by the SDGSAT-1 satellite, scientists have created the first high-resolution calibrated light pollution map of the Iberian Peninsula.

With an unprecedented resolution of 40 meters, the RALAN-Map EU project has been directed by astrophysicist Alejandro Sánchez de Miguel from the Department of Earth Physics and Astrophysics at the Complutense University of Madrid (UCM) in Spain, in collaboration with the International Big Data Research Center for Sustainable Development Goals (CBAS).

The map of the Iberian Peninsula stands out for its complete coverage, also including the Canary Islands, Madeira and the Balearic Islands.

This map represents a significant advance in the study of light pollution, allowing a more precise evaluation of its impact on the environment and human health.

One of the most notable features of this map is its ability to provide an estimate of the color temperature of the light sources studied, a crucial factor in understanding the effects of artificial light at night.

The presentation of this map opens new avenues for research and decision-making regarding lighting management and protection of the night sky.

This project is not only a milestone for the researchers and scientists involved, but also a valuable resource for governments, urban planners, and conservationists seeking sustainable solutions to the growing problem of light pollution.

The team behind RALAN-Map EU continues to work on improving and refining this map, with the aim of providing an even more accurate and useful tool for the global community. (Source: UCM)
