The images were released as a part of the project where NASA studies in a bid to study migratory trends. A similar set of images were released in the year 2012, and hold some intrigue and scientific curiosity among the closed circle of intellect. Often termed as Night Lights, a term used to refer to the images clicked by satellites at night. These have been around for more than 25 years and goes in some way to predict how we have evolved as humans.

NASA, after the launch of the NOAA Suomi National Polar-orbiting Partnership (NPP) satellite, has been constantly developing new software and algorithms for analyzing night imagery data and give us more accurate and precise result.

The major obstacle that still exists is, that the process of imaging depends on a lot of external factors that needs to be taken into account. For example, the phases of the moon can have disturbing effects on the imagery, though a correction bias is not difficult to fix for. In a similar manner, clouds, smog, aerosols and other strictly Physics phenomenon like auroras.

The data collection by the Suomi NPP usually happens between 1:30 AM to 1:30 PM and observes the night lights traveling 3000km vertically from pole to pole. This data carries relevance with regard to short-term weather forecasting and first-hand disaster response.
