Global Deprivation Index: Night-Lights Trend Layer

GRDI VNL Slope Constituent Raster
land NASA VEDA COG
In plain English

What it measures. One ingredient of the worldwide relative-deprivation map, capturing whether an area's night-time brightness has been rising or falling over time as a sign of changing development.

How it's made. Built from the trend (slope) in VIIRS satellite night-time lights over multiple years, fed into the larger Global Gridded Relative Deprivation Index.

How & where you'd use it. Helps spot places where development is stalling or improving, guiding longer-term aid and policy decisions.
