OpenStreetMap is a free, editable map of the whole world that is being built by volunteers largely from scratch and released with an open-content license. The OpenStreetMap License allows free (or almost free) access to our map images and all of our underlying map data.
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 open and accessible maps 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 organizations are trying to meet the needs of people who live at risk of disasters and crises.
Ushahidi is a global not-for-profit technology company that develops integrated tools and services to enable people to generate solutions and mobilize communities for good. We build our open-source software with the intent of strengthening communities and improving lives, empowering users to rapidly and purposefully gather, analyze, respond and act on data and information.
Since our founding in 2008 as a tool to monitor and map post-election violence in Kenya, Ushahidi’s crowdsourcing tools have been used by thousands of groups and millions of people to raise voices, inform decisions, stop suffering and influence change.
The Zooniverse is the world’s largest and most popular platform for people-powered research. This research is made possible by volunteers — more than a million people around the world who come together to assist professional researchers. Our goal is to enable research that would not be possible, or practical, otherwise. Zooniverse research results in new discoveries, datasets useful to the wider research community, and many publications.
