When seen from the space the night time view tells us a tale about everything ranging from electricity consumption to population and poverty.
Researchers have now developed an online mechanism which can merge the night-time light data of the last 21 years. This will help in understanding and comparing variations in the human activities over the years.
The tool operates by comparing the brightness of the light at country’s night time with the electricity consumption, poverty etc. It was found that brightness of lights and poverty were inversely related. The tool is said to be capable of making us understand the relationship between human activities and socio economic factors, globally. It does not need us to rely on national statistics and numbers for any information.
The research was based on the thought that greater discoveries could be made by merging huge database sets with technological mechanisms.
