Crisis mapping (also known as disaster mapping) is the real-time gathering, display and analysis of data during a crisis, usually a natural disaster or social/political conflict (violence, elections, etc.). Crisis mapping projects usually allows large numbers of people, including the public and crisis responders, to contribute information either remotely or from the site of the crisis. One benefit of the crisis mapping method over others is that it can increase situational awareness, since the public can report information and improve data management.
Crisis mappers work with data that comes from diverse sources and can be produced for varying purposes. As such, there is some overlap with big data, international development, and community engagement.
