Night-lights piece of the global deprivation index, from CIESIN's GRDI dataset

GRDI VNL Constituent Raster
land NASA VEDA COG
In plain English

What it measures. One ingredient of the worldwide relative-deprivation map, using how brightly each area glows at night as a clue to its level of development and activity.

How it's made. Built from VIIRS satellite night-time lights imagery, fed into the larger Global Gridded Relative Deprivation Index.

How & where you'd use it. Helps reveal less-developed regions where dimmer night lighting can signal underserved communities.
