Night Score
A comparable 0โ100 measure built from sky brightness, visible stars and local conditions.
A COMMUNITY-POWERED LIGHT POLLUTION MAP
MAP THE DARK.
BRING BACK
THE STARS.
Take one night-sky reading. See how your city compares. Add a trusted data point to a public map that helps communities understand โ and reduce โ light pollution.

ONE CLEARER VIEW OF OUR NIGHT
Measure your sky
in under 60 seconds.
This browser prototype estimates a preliminary Night Score from observations you can make with the naked eye. The field pilot will add calibrated image analysis.
A public record of
the disappearing night.
The production map will show verified, privacy-safe observations. Until the pilot begins, we show the protocol and data layers โ not invented activity.

Darker skyModerate glowSevere glow
Change over time
Repeat readings reveal whether a neighbourhood is getting brighter or recovering its night sky.
City comparison
Aggregated scores create clear, shareable city benchmarks without exposing exact observer locations.
Action layer
Community missions connect measurements to lighting audits, awareness campaigns and before/after evidence.
Useful data needs
more than a photo.
NOCTRA separates participation from verification. Every submission can contribute, but only quality-checked readings enter the public index.
Capture
The app guides angle, exposure and timing. Device model and weather context support calibration.
Protect
Exact coordinates are converted to a coarse grid. Original images and identifying metadata are not published.
Verify
Duplicate detection, anomaly checks, repeated readings and trusted reviewers assign a confidence level.
Publish
Approved observations enter an open, versioned dataset with method notes and clear uncertainty.
OPEN DATA COMMITMENTAggregated observations will be downloadable under a permissive licence. Method changes will be versioned, documented and reproducible.
PRIVACY COMMITMENTNOCTRA will never sell precise location trails. Public map cells will be deliberately coarse, especially near homes and sensitive habitats.
Measure. Compare.
Change the light.
A map matters only when people can act on it. Night Missions turn observations into practical local projects.
Map one neighbourhood
Five observers, three nights, twenty verified readings. Produce a baseline residents can understand.
COMMUNITYAudit one street
Document glare, spill and unnecessary fixtures, then publish a simple evidence pack for local decision-makers.
ACTIONProve the change
Return after an intervention. Compare the same locations, conditions and hours to show what improved.
IMPACTValue created by
useful participation.
$NCTR coordinates the people who improve NOCTRA's data, fund local action and govern shared resources. The map remains open; the token makes the network stronger.
$NCTR
Reward trusted contribution
Verified observers, reviewers and calibration hosts can earn rewards for sustained, high-quality work. Upload volume alone creates no entitlement.
Turn treasury into visible impact
Community-approved grants fund sensors, open-source tools, local lighting audits, education and repeat measurements that prove change.
Give committed members a voice
Token holders can help prioritise missions, treasury grants and protocol upgrades. Scientific methodology remains evidence-led and independently reviewed.
Unlock contributor tools
Active contributors can access deeper city comparisons, mission coordination and verified field credentials without placing core public data behind a paywall.

THE FIRST
NIGHT MAP.
We are recruiting astronomers, designers, developers, community organisers and curious night walkers to test the protocol before public data collection.
