Methodology and trust

How we decide a dot’s colour, size and freshness, and when we call it verified. The same fixed rules apply to every story, so every label can be explained.

Colour: impact on people, not tone

We first record the facts of what happened (type of event, place, time, whether it is ongoing, whether a road is blocked, injuries). Fixed rules then set the colour.

ColourRuleExamples
BadHarm to people, or the road or area is unsafe or blockedAttack, kidnapping, crash with injuries, flooding over the road, fire
CautionDisruption, delay or risk, but passableTraffic, roadworks, protest, fuel queues, checkpoints, weather warning
GoodSomething got safer or easierRoad reopened, bridge finished, curfew lifted
NeutralInformation with no immediate effectBudgets, announcements, plans

A story with a positive tone in a still-risky area stays Caution: for example, kidnap victims rescued while the threat remains.

Size: severity 1 to 5

SizeMeaning
5Deaths or an attack
4Serious injuries, or a major road closed
3Road blocked for hours
2Significant delay
1Minor delay or disruption

Freshness

“Now” means reported or updated in the last 60 minutes and still ongoing. Dots fade with age and are archived at the end of their lifetime:

Flooding3 days
Road closure2 days

Archived events are still shown when you pick a past date.

Verified or not

A dot is verified when two independent sources report it, when a trusted agency feed reports it, or when two people on the road confirm it. Until then it is shown hollow and marked unverified.
