“…Integrating additional controls with a web-based remote visualization service has the potential to facilitate additional remote interaction features with this service. The remote webcam service can be modeled after the Web-Based Data Interrogation System (WEB-IS) (GARBOW et al, 2003 andWANG et al, 2004) / www.vlab.msi.umn.edu], are now in a position to embrace webcam in order to fulfill goals aimed at educational outreach and bridging gaps between disciplines in the geosciences. By allowing different webcam systems to communicate with each other, less commonly used operating systems, such as Macintosh and Linux, are now able to take part in collaboration and outreach where they had previously been neglected.…”

“…We describe a costeffective data exploration system using remote webcam technologies that can be integrated into the iSERVO network as a web-based component. The remote webcam service will be based on the framework of our Web-based Data Interrogation System (WEB-IS) (GARBOW et al, 2003;WANG et al, 2004). This system will allow visualizations and the analysis to be quickly transmitted to collaborating researchers, decision makers, and the broader community.…”

Visualizing and analyzing datasets in the geosciences is becoming increasingly complicated as their volumes are growing explosively. This poses a challenging problem for researchers who must sift through terabytes of data to discover useful relationships inside the information. There is a great need for geophysicists to interactively explore their data sets. Conventional visualization systems lack adequate bandwidth and rendering capabilities necessary for the largest data sets. CAVE and Powerwall display devices are necessary for researchers to explore their data sets in an immersive setting. We describe a utilitarian system targeted specifically at the cost-effective interactive exploration of data sets tens of terabytes in size and harness this system for visualization and analysis of geophysical simulations. Webcams can be used as a steering device to track a local region of interest, which is useful for remote visualization of large data sets. This system will be employed as a web-service under the auspices of Narada-Brokering, while using webcam technologies to enable remote visualization for collaborating researchers. Webcams can be incorporated in a point-to-point network for rapid exchange of information and quickly announcing natural disasters, such as tsunamis, landslides and earthquakes.

“…In order to view the data locally, we have utilized the University of Minnesota Laboratory for Computational Science and Engineering's PowerWall (http://www.lcse.umn.edu), a high-resolution display wall, to achieve high resolution parallel visualization of multiple fields simultaneously. For remote visualization, we have developed a system for web-based image services which is now incorporated into our WEB-IS visualization toolkit (Garbow et al, 2003;Wang et al, 2003;Yang et al, 2003).…”

Visualization of multi-scale dynamics of hydrous cold plumes at subduction zones

et al. 2004

Recent increases in the computational power of high-performance computing systems have led to a large gap between the high-resolution runs of numerical simulations -typically approaching 50 to 100 million tracers and 1 to 5 million grid points -and the modest resolution of one to two million pixels for conventional display devices. This technical problem is further compounded by the variety of fields produced by numerical simulations and the limited bandwidth available through the Internet in the course of collaborative ventures. We have developed a visualization system using the paradigm of web-based inquiry to address these mounting problems. We have employed as a case study a problem involving two-dimensional multiscale dynamics of hydrous cold plumes at subduction zones. A Lagrangian marker method, in which the number of markers varies dynamically, is used to delineate the many different fields, such as temperature, viscosity, strain, and chemical composition. We found commercially available software to be insufficient for our visualization needs and so we were driven to develop a new set of tools tailored to high-resolution, multi-aspect, multiscale simulations, and adaptable to many other applications in which large datasets involving tens of millions of tracers with many different fields are prevalent. In order to address this gap in visualization techniques, we have developed solutions for remote visualization and for local visualization. Our remote visualization solution is a web-based, zoomable image service (WEB-IS) that requires minimal bandwidth while allowing the user to explore our data through time, across many thermo-physical properties, and through different spatial scales. For local visualization, we found it optimal to use bandwidth-2 intensive, high-resolution display walls for performing parallel visualization in order to best comprehend the causal and temporal relationships between the multiple physical and chemical properties in a simulation.
