Help Us Map!

We are both “HOT members” and volunteers from the wider OpenStreetMap community. When a disaster or political crisis happens, HOT leaps into action to map the affected area with a global network of volunteers. Disaster responders, such as the Red Cross and Doctors without Borders, are using these detailed maps in the response to these crises.

Anyone can get involved!
