MapAction

MapAction We make aid work better thanks to our unique combination of deep expertise in geospatial information

MapAction works across the globe to ensure humanitarian teams have access to the information they need to make key decisions, at the right time, to save lives and alleviate suffering. Our vision is of a world where people vulnerable to humanitarian emergencies are more resilient, and those assisting them are more effective, through the use of technological advances in information management. After

more than 20 years of experience and learning carefully gleaned from attending over 120 different humanitarian emergencies and supporting countless more, we have developed a unique human capacity to apply geospatial insight to tackle big problems. We help humanitarians make rapid sense of chaotic, dangerous and rapidly evolving situations. We do this during a crisis - anywhere in the world, and at just 24 hours notice - but also before and after a crisis. When emergencies happen, the entire global MapAction knowledge base is immediately on hand to assess which data is available to support decision making, whether it is reliable enough, and which maps, data and visualisation products have worked best in similar situations. We don’t ask what maps are needed, but which decisions need to be supported. Sometimes it’s not a map that’s required, but a dashboard, a cleaned data set or another form of spatial analysis or visualisation. Our team has the skills and knowledge to recognise and provide it. Away from crisis response, we share the very specialist knowledge we have acquired, by teaching and training humanitarian coordinators to use maps and other specialist geospatial data products to help them make better decisions, improving humanitarian outcomes. We’re also developing new systems to ensure the essential data we know to be indispensable in humanitarian crises is prepared ahead of time and made available automatically, as soon as it’s needed.

🗾 🇫🇲 A MapAction map in response to Cyclone Sinlaku in the Federated States of Micronesia shows the estimated population across 20 of the federation's municipalities in the core states of Yap, Pohnpei, Kosrae and Chuuk. Chuuk suffered particular damage.

🌀 ⚠️ "Chuuk State is experiencing severe and widespread humanitarian impacts following the passage and stalling of Tropical Storm (Typhoon) Sinlaku," states an April 20th update from the UN's ReliefWeb portal. "Critical infrastructure has been heavily affected, including power generation systems, water supply, communication networks, roads, and port facilities," adds the update.

MapAction volunteers Felicity Cross and Claudia Offner have just wrapped up their deployment supporting the Hurricane Melissa response in Jamaica. They’ll soon be replaced by Kirsty Ferris, who will remain in Kingston to support the World Food Programme’s efforts for the next month.

Felicity and Claudia spent their time in Kingston and Montego Bay producing critical maps to support coordination and relief efforts — from situational overviews, to telecommunications and access mapping 🗺. They recorded some of their activities to give you a flavour of a MapAction mission, though no two are the same. Check out the Daily Coordination Meeting at 0:25, where MapAction’s Common Operational Overview Map takes centre stage 📍

Many thanks to Sweco and British Antarctic Survey for allowing us to borrow Felicity and Claudia for this life-saving work.

We’re proud of the impact our teams make, and we also rely on donations to keep responding when disasters strike. To support our future missions, please visit mapaction.org/donate 🙏.

What better thing to do on a cold and wet weekend than a MapAction team training?

Close to 50 volunteers and some staff came together, at a scout camp outside Milton Keynes for the final face-to-face training of 2025.

Today has sessions on team building, Web mapping, and lessons from the ongoing Hurricane Melissa deployment, presented by Kirsty Ferris and Indigo Brownhall.

MapAction members are briefly featured in 'GIS on the Frontline', a video by the Ministry of Economic Growth and Job Creation in Jamaica. The interviewees are discussing the broader government's strategy but it sums up why MapAction makes maps for emergencies.

"When Hurricane Melissa struck Jamaica, maps became just as vital as manpower," states Alicia Edwards, principal director, National Spatial Data Management Branch (Jamaica).

"It was important for us as a government to understand what was the level of impact. What happened? And where did it happen? Where were areas that were flooded? Where were areas that were impacted by houses that were damaged?...So mapping became important," recalls Simone Lloyd, GIS manager and trainer at the National Spatial Data Management Branch.

🇯🇲Why might humanitarian planners in an emergency response need maps based on the latest data? To plan how to get where in a landscape where the geography has changed and where complex operations are evolving by the hour. Yesterday humanitarian partners of MapAction in Jamaica used one of our maps, for example, to plan how to reach marooned and affected communities by helicopter.
Maps save lives.
