Humanitarian OpenStreetMap Team (HOT) is a global NGO that creates and provides digital and print maps to address the world's toughest challenges. In times of crisis and natural disaster, HOT rallies a network of volunteers to rapidly produce maps relied upon by humanitarian relief organizations to reach those in need.

Your donation is needed urgently to map the world’s most vulnerable and least mapped places through Microgrants, before the next disaster. 100% of each Microgrant donation goes to a local leader who is transforming their country by filling in critical data gaps.

  • HOT has trained more than 3,000 people in mapping in some of the world’s most vulnerable places over the past 5 years

Mapping vulnerable places in the world takes a global community. HOT is your community, your map, and is supported by your generosity. Could you donate any amount today to help make this life-changing work possible?

As a registered 501(c)(3) nonprofit organization your donation is tax deductible in the United States.

HOT and OSM communities around the world rely on the OpenStreetMap Foundation (OSMF). Become an OSMF member today.
