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)
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)
Emergency response requires strategic assessment of risks, decisions, and communications that are time-critical 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)
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)
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 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)
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)
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(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)
A novel interface system for accessing geospatial data (GeoMIP) has been developed that realizes a user-centered multimodal speech/gesture interface for addressing some of the critical needs in crisis management. In this system we primarily developed vision sensing algorithms, speech integration, multimodality fusion, and rule-based mapping of multimodal(More)
