The Crisis Mappers Network

The International Network of Crisis Mappers (Crisis Mappers Net) is an international community of experts, practitioners, policymakers, technologists, researchers, journalists, scholars, hackers and skilled volunteers engaged at the intersection of humanitarian crises, new technology, crowd-sourcing, and crisis mapping. The Crisis Mappers Network was launched at the first International Conference on Crisis Mapping (ICCM) in 2009 at John Carroll University in Cleveland, Ohio. Since then we convened conferences for the global community in Boston, Geneva, Washington, Nairobi, New York, and Manila, with different hosts in each location, including Harvard, Tufts, the Swiss Confederation, the European Union's Joint Research Centre, the World Bank's GFDRR & World Bank Institute, George Washington University, the United Nations Office at Nairobi, UN-Habitat, Spatial Collective, The Humanitarian Design Lab at Parsons The New School of Design, Google Crisis Response, & Map the Philippines. Our last ICCM took place in 2016.

Crisis Mappers leverage mobile & web-based applications, participatory maps & crowdsourced event data, aerial & satellite imagery, geospatial platforms, advanced visualization, live simulation, and computational & statistical models to power effective early warning for rapid response to complex humanitarian emergencies. As information scientists we also attempt to extract meaning from mass volumes of real-time data exhaust.

This group includes 9,600+ members in over 160 countries, who are affiliated with over 3,000 different institutions, including  more than 400 universities, 50 United Nations agencies & projects, first responders operating in both the civilian and military space, dozens of leading technology companies, several volunteer & technical community networks and global, national, and local humanitarian and disaster response and recovery organizations.

Crisis Mappers Net is not an organization or institution, and deliberately so. All of us connected here have very different goals, aims, strengths, interests, and backgrounds. As a network, we offer a neutral space for conversation and information sharing.  As volunteer administrators, we manage the website & google group to facilitate collaboration. Thus, it is the important work of the members themselves that makes this group what it is.
