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)
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)
Vast digital data resources are being produced that include geospatial referencing, from precise geographic coordinates (e.g., generated by GPS receivers in vehicles , PDAs, cell phones, and other devices), through street addresses, to codes for administrative and other regions (e.g., zip codes, census tracts FIPS codes, drainage basin indices). A few(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)
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)
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)
Crisis events have dramatic impact on human society, economy and our environment. Geographical information and intelligence play a key role in crisis management activities. However, the use of geographical information technologies in responsible government agencies has been mostly confined to single users, and within single agency. An interdisciplinary team(More)
