Abstract
Lack of relevant information, particularly geospatial information, is one of the major challenges in emergency management. In the past few years, geospatial information created by volunteers and facilitated by social networks has become a promising data source in time-critical situations. This paper discusses the roles that social networks can play in the crowdsourcing of geospatial information for emergency management, data generation and dissemination through social networks, and investigates the relationships and interactions in social networks. Research issues arise in the areas of data access, data quality, information synthesis, emerging patterns of human behaviors in emergencies, analysis and visualization of nested social networks, implementation of information systems for emergency management, privacy, and equity.
