THE DARK SIDE OF EARTH – CAN YOU STILL SEE THE STARS? 🌌

Not all that shines is starlight!

For Day 5 of the #30DayMapChallenge, exploring the world after dark through satellite-observed night-time illumination. Mapping how artificial lights illuminate our planet and revealing the darker regions where the night sky may still offer a glimpse of the stars.

Data swizzling using #FME from Safe Software and Cartograph-ing with #QGIS.

Data Integration: Country-wise night-time radiance data processed using #FME.

Visualization: Global choropleth map based on Average Night-time Radiance (2023), measured in nW/cm²/sr.

Data Sources:

• World Population Review – Darkest Countries – Average Radiance 2023.
