Emergency response requires strategic assessment of risks, decisions, and communications that are timecritical while requiring teams of individuals to have fast access to large volumes of complex information and technologies that enables tightly coordinated work. The access to this information by crisis management (CM) teams in emergency operations centers(More)
Most work with geospatial data, whether for scientific analysis, urban and environmental planning, or business decision making is carried out by groups. In contrast, geographic information technologies have been built and assessed only for use by individuals. In this paper we argue that, to support collaboration with geospatial information, specific(More)
Most work with geospatial data, whether for scientific analysis, urban and environmental planning, or business decision making is carried out by groups. In contrast, geographic visualization environments and related geographic information technologies have been built and assessed only for use by individuals. In this paper, we describe a prototype(More)
Current computing systems do not support human work effectively. They restrict human-computer interaction to one mode at a time and are designed with an assumption that use will be by individuals (rather than groups), directing (rather than interacting with) the system. To support the ways in which humans work and interact, a new paradigm for computing is(More)
Geovisualization is both a process for leveraging the data resources to meet scientific and societal needs and a research field that develops visual methods and tools to support a wide array of geospatial data applications. While researchers have made substantial advances in geovisualization over the past decade, many challenges remain. To support(More)
This research presents an overview of the implementation strategies, results, and lessons learned from an onsite Work Domain Analysis for the design of a multimodal emergency management GIS for hurricane response. An overview of the onsite visits including details of the knowledge elicitation techniques used (e.g. critical incident analysis, concept(More)
Collaboratories have been deWned as centers without walls, virtual places where teams of scientists can undertake coordinated research. As part of the Human–Environment Regional Observatory (HERO) infrastructure project, we have been developing a geocollaboratory to support work by geographically distributed scientists about geographic problems. Our speciWc(More)
Geospatial information is critical to effective, collaborative decision-making during emergency management situations; however conventional GIS are not suited for multi-user access and high-level abstract queries. Currently, decision makers do not always have the real time information they need; GIS analysts produce maps at the request of individual(More)
Current mapping and related geospatial technologies are not designed to support group work and we have a limited theoretical or practical basis from which to extend (or reinvent) technologies for group use of geospatial information. To address the challenge of supporting group work with geospatial information, we have developed a comprehensive conceptual(More)
Science and decision making activities involving geographic information are usually carried out by groups. However, current mapping and related geospatial technologies are not group-friendly and attempts to extend (or reinvent) technologies for group use have been largely ad hoc. Elsewhere, we have developed a comprehensive conceptual approach to(More)
