The document introduces the Standby Volunteer Task Force, an online community of over 150 volunteers from 17 countries who assist with crisis mapping during emergencies. The Task Force participated in simulations of earthquakes in Haiti, Chile, and Colombia to test their ability to collect and verify reports, map data, analyze information, and provide support to humanitarian organizations. Feedback from UN organizations was positive, seeing the Task Force as a way to better incorporate community-generated data into emergency response efforts. The document argues that online volunteer communities like the Task Force can play an important role in facilitating communication between affected communities and humanitarian groups during crises.
