Reposting mit aktualisierten Daten, die 2012 Composite verwendete eine andere Methode und eine teilweise Abdeckung, die einige Regionen (wie Thailand) dunkler erscheinen ließ. Diese Version verwendet Durchschnittliche jährliche maskierte VIIRS -Daten Für einen faireren Vergleich 2014–2024.

      Some people asked why Thailand looked dark in the 2012 map I shared earlier. That happened because:

      * The **2012 composite used a different processing method (VCMCFG)** and only covered part of the year.
      * Thailand in particular had **gaps in that dataset**, which made it look like there were no lights.
      * For this repost I’m using the **average annual masked composites (2014 & 2024)**, which filter out ephemeral lights (fires, boats, etc.) and give a much more reliable view of stable night-time lights.

      Here’s also the Thailand-only map for closer detail.

      I think this highlights something I noticed while living in Seoul that entire decade. There was an explosion of development in SEA, mainly indonesia, malaysia, thailand and vietnam. In 2014 , your only tourists were chinese. Now, you get all the above
      Mentioned countries in large quantities.

    3. One thing I’m curious about, what „causes“ the different tones of light color in different areas, especially India compared to the rest of the map?

      The mega urban area of Shanghai and surrounding towns/cities in Jiangsu and Zhejiang is crazy.

    5. So who’s gonna tell me what happened in kandyagash, Kazakhstan between these years, was it nuked?

      Beautiful to see this GDP growth, making a reference to a paper that shows the correlation between light at night and GDP growth.
