Geographic data and tools are essential in all aspects of emergency management: preparedness, response, recovery, and mitigation. Geographic information created by amateur citizens, often known as volunteered geographic information, has recently provided an interesting alternative to traditional authoritative information from mapping agencies and corporations, and several recent papers have provided the beginnings of a literature on the more fundamental issues raised by this new source. Data quality is a major concern, since volunteered information is asserted and carries none of the assurances that lead to trust in officially created data. During emergencies time is the essence, and the risks associated with volunteered information are often outweighed by the benefits of its use. An example is discussed using the four wildfires that impacted the Santa Barbara area in 2007Á2009, and lessons are drawn. 1. Introduction Recent disasters have drawn attention to the vulnerability of human populations and infrastructure, and the extremely high cost of recovering from the damage they have caused. In all of these cases impacts were severe, in damage, injury, and loss of life, and were spread over large areas. In all of these cases modern technology has brought reports and images to the almost immediate attention of much of the world's population, and in the Katrina case it was possible for millions around the world to watch the events as they unfolded in near-real time. Images captured from satellites have been used to create damage assessments, and digital maps have been used to direct supplies and to guide the recovery effort, in an increasingly important application of Digital Earth. Nevertheless it has been clear in all of these cases that the potential of such data, and of geospatial data and tools more generally, …
