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

Started in 2010 from the Earthquake in Haiti, HOT's goal grew out of the need to add everyone to the map.

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

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.
