Nightlight

VIIRS → 25m super-resolution

Artificial light at night is a direct proxy for human and industrial activity — power availability, urban expansion, conflict disruption, and the rhythm of economic life. The standard source, NASA's Black Marble, is only 500m, too coarse to resolve neighbourhoods or individual facilities.

EarthToDate super-resolves nightly VIIRS night-lights to 25m, updated worldwide whenever skies are clear. At this resolution a power outage, a newly electrified district, or an idled industrial site becomes individually visible.

Typical uses include grid-reliability and outage monitoring, economic-activity nowcasting, and detecting urban or industrial change between any two nights.

Frequently asked questions

What is Nightlight?

Artificial light at night is a direct proxy for human and industrial activity — power availability, urban expansion, conflict disruption, and the rhythm of economic life. The standard source, NASA's Black Marble, is only 500m, too coarse to resolve neighbourhoods or individual facilities.

What data and resolution does Nightlight use?

Nightly 25m night-lights, super-resolved from NASA Black Marble, for power, outage, and activity tracking. (VIIRS → 25m super-resolution)

Where and how often is it available?

EarthToDate super-resolves nightly VIIRS night-lights to 25m, updated worldwide whenever skies are clear. At this resolution a power outage, a newly electrified district, or an idled industrial site becomes individually visible.
