Özet

In this study, we investigate the effects of light pollution in France using GIS data which was first used in Aksaker et al. (Mon. Not. R. Astron. Soc. 493:1204, 2020) (so called astroGIS database - astrogis.org). A subset of Artificial Light layer of astroGIS database has been adapted for years between January 2012 and December 2019. During 2019, half a million of lumen has been released into space from the total surface area of France. Annual light pollution in France has a decreasing trend. France continues to have potential Dark Sky Park locations for example cities like Cantal, Lot, Lozere and Creuse having the lowest light pollution values. Light pollution is strongly correlated with population (R-2 similar or equal to 0.85) and GDP (R-2 similar or equal to 0.84). In addition, half of the observatories remain under the light polluted areas.
