When disasters strike, the first thing responders need is an accurate map. But for much of the world, detailed maps don’t exist. Humanitarian OpenStreetMap Team (HOT) has been fulfilling that need since 2010. Today, HOT is a global network of over 500,000 contributors across 94 countries. By combining local ground-truth mapping, regional hubs, and open source tools, HOT coordinates massive, crowdsourced efforts to provide immediate data to responders without licensing costs or procurement barriers.
