Humanitarian OpenStreetMap Team

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. Free, collaborative maps are uniquely valuable to humanitarian work, especially in places where base map data is often scarce and out of date. OpenStreetMap is a web project to create a free and open map of the entire world, built entirely from volunteers surveying with GPS, digitizing aerial imagery, and collecting and liberating existing public sources of geographic data.
