Managing crises requires collecting geographical intelligence and making spatial decisions through collaborative efforts among multiple, distributed agencies and task groups. Crisis management also requires close coordination among individuals and groups of individuals who need to collaboratively derive information from geospatial data and use that information in coordinated ways. However, geospatial information systems do not currently support group work and can not meet the information needs of crisis managers. This paper describes a group interface for geographical information system, featuring multimodal human input, conversational dialogues, and same-time, different place communications among teams.
