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)
In information systems that support knowledge-discovery applications such as scientific exploration, reliance on highly structured ontologies as data-organization aids can be limiting. With current computational aids to science work, the human knowledge that creates meaning out of analyses is often only recorded when work reaches publication – or worse,(More)
Simply placing electronic geoscience resources such as datasets, methods, ontologies, workflows and articles in a digital library or cyberinfrastructure does not mean that they will be used successfully by other researchers or educators. It is also necessary to provide the means to locate potentially useful content, and to understand it. Without suitable(More)
Representations of scientific knowledge must reflect the dynamic nature of knowledge construction and the evolving networks of relations between scientific concepts. In this article, we describe initial work toward dynamic, visual methods and tools that support the construction, communication, revision, and application of scientific knowledge. Specifically,(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)
This paper discusses a portal used by geoscientists and human-environment relations researchers to capture and share the evolution of concepts and the emergence of agreement through collaboration. A concept graph interface to the portal encodes relationships among people, concepts, data, tools, tasks, times, and places. By linking resources in flexible and(More)
