The Digital Humanitarian Network (DHN) is a network of organizations that provide information-based response and relief services to communities affected by disaster events and formal response actors directly servicing these populations. HOT is a Network Member of DHN.

The Global Facility for Disaster Reduction and Recovery (GFDRR) works together with HOT on data collection efforts in a number of countries. Past projects have included Bangladesh, Malawi, Sri Lanka, and Vietnam. HOT is a contributing author to GFDRR's Planning an Open Cities Mapping Project guide and the second round of the Challenge Fund initiative.

A 2014-15 grant from the Hewlett Foundation supported building HOT's capacity to respond to the West Africa Ebola epidemic as well as future crises. This grant supported development of training as well as technology tools including Field Papers and the OSM Export Tool.

Support from the Humanitarian Innovation Fund's Large Grants facility supported the development and launch of OpenAerialMap in 2015.


The Knight Foundation Prototype Fund provided generous support for the development of OpenMapKit (2014) and the OSM Data Analysis Tool (2015-16).


MapGive, an initiative of the U.S. Department of State’s Humanitarian Information Unit, makes it easy for new volunteers to learn to map and get involved in online tasks. HOT works closely with MapGive on training material and coordinating the work of volunteer mapping projects.

Each year, disasters around the world kill nearly 100,000 and affect or displace 200 million people. Many of the places where these disasters occur are literally 'missing' from any map and first responders lack the information to make valuable decisions regarding relief efforts. Missing Maps is an open, collaborative project in which you can help to map areas where humanitarian organisations are trying to meet the needs of vulnerable people. HOT is a founding member of Missing Maps alongside the American Red Cross, British Red Cross, and Medicins Sans Frontieres.

HOT and the U.S. Peace Corps (via the Peace Corps' Office of Innovation) have worked together since 2013 to help integrate the use of OpenStreetMap into Peace Corps Volunteers' deployments. In 2016, HOT joined the Peace Corps in promoting International Women's Day with a series of mapping events led by and focused on women.

The World Bank and HOT have collaborated on the Open Cities project, and the World Bank currently supports HOT OpenStreetMap training and data collection projects in a number of countries.

The U.S. Department of State Bureau of Population, Refugees, and Migration, through the Urban Innovation Program, supports HOT programming in northern Uganda and Istanbul, Turkey in response to refugee crises.

YouthMappers is an international network of university student group chapters dedicated to mapping real-world challenges. YouthMappers is an activity of MappersU, a mapping for resilience international university consortium co-founded by Texas Tech University, George Washington University, West Virginia University, and the USAID GeoCenter. In 2015, the program formalized collaboration through a public launch and a four-year grant from the USAID GeoCenter.
