Crisis Camp is a global network of volunteers with technology and crisis response skills who collaborate to improve tools and practices for humanitarian crisis management and disaster relief. It was founded in 2009 in response to crises like the Haiti earthquake and holds regular camps where volunteers work on open source projects. At camps, volunteers from various skills and backgrounds contribute to tools like Ushahidi, OpenStreetMap, and Sahana to support organizations responding to disasters and emergencies around the world.
