Seeing changes in the world through images of the world at night

A really interesting set of maps about changes in night lights.

“John Nelson, a cartographer at Esri, a digital mapping company, was curious what these lights could tell us about how the world around us had changed over time. Had some areas grown brighter while others had dimmed? And if so, he wondered, what was behind these changes? 

So Nelson used NASA’s satellite images from 2012 and 2016 and calculated the difference in light pixels to see which areas of the world had grown more luminous and which areas went dark.

The resulting maps shows where lights have increased in blue and where lights have diminished in pink in the past five years.”
