Humanitarian OpenStreetMap Team (HOT)

HOT is an international team dedicated to humanitarian action and community development through open mapping. We work together to provide map data which revolutionises disaster management, reduces risks, and contributes to achievement of the Sustainable Development Goals.

When major disaster strikes anywhere in the world, thousands of HOT volunteers come together online and on the ground to create open map data that enables disaster responders to reach those in need.

Through the Missing Maps project, the HOT global community creates maps of high vulnerability areas where data is scarce, putting millions of people onto the world map in OpenStreetMap.

HOT enables communities, NGOs, international organizations, and government partners to use and contribute to OpenStreetMap for locally-relevant challenges through provision of training, equipment, knowledge exchange, and field projects.

HOT develops open source apps and tools for collaborative mapping and geospatial data collection. Our tools are free for all to use and leveraged by partners such as Red Cross societies, Médecins Sans Frontières, UN agencies and programmes, government agencies, and local NGOs and communities.
