Ushahidi crisis mapping

2008Nairobi, KenyaOry Okolloh, Erik Hersman, Juliana Rotich and David KobiaDocumented

The problem

During Kenya's post-election violence in early 2008, reports of attacks were scattered across blogs, phone calls and text messages with no way to see the whole picture.

The innovation

An open-source platform that collects reports by SMS, email and web and places them on a map in near real time — crowdsourced situational awareness.

How it worked

Incoming reports are geolocated, categorised and verified where possible, producing a live map that anyone can read.

Why it mattered

Deployed afterwards for the Haiti and Chile earthquakes, election monitoring, disease response and disaster relief worldwide.

The legacy

Crisis mapping as a discipline largely dates from this deployment; the software remains open source.
