Abstract: Disaster response organizations are ad-hoc assemblies of multiple emergency services that collaborate with the goal to minimize the number of casualties and possible (infra)structural damage. In order to be effective, emergency personnel not only needs shared awareness of the situation but also awareness of the organization. We propose an organization awareness support system that contains a dynamic organigram that provides people with a real-time visualization of the organization that they belong to. © Proceedings ISCRAM 2004.
