We present a web client-server service WEB-IS for remote analysis and visualization of seismic data consisting for both small and large earthquakes. We show that a problem-solving environment (PSE) designed for predicting of large magnitude earthquakes can be based on this WEB-IS idea. The clustering schemes, feature generation, feature extraction… (More)
We discuss a software tool we have developed for remote visualization and analysis of large-scale geophysical datasets, such as earthquakes. To overcome the limitations created by the current and future deluge of data, our system, called WEB-IS (http://boy.msi.umn.edu/WEB-IS), utilizes a client-server paradigm to harness the power of a large visualization… (More)
The faster growth curves in the speed of GPUs relative to CPUs in the past decade and its rapidly gained popularity have spawned a new area of development in computational technology. In the past several years, non-graphical applications have been adapted to the GPU by means of several improved programming models. There is much potential in utilizing GPUs… (More)
WEB-IS, Web-based Integrated System, allows remote, interactive visualization of large-scale 3-D data over the Internet, along with data analysis and data mining capabilities. In this paper, we discuss the overall view for WEB-IS. We have developed three sub-modules in WEB-IS: WEB-IS1 allows users to navigate through their rendered 3-D data and… (More)
A 3D visualization environment contains domain information about geologic features in seismic data and lets users interactively steer segmentations on the basis of visual sources of information and knowledge. A user study demonstrates this approach's ability to transfer domain knowledge to non experts.
—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… (More)
Wavelet compression methodologies promise significant computational and storage cost savings through the benefit of producing results on adapted grids that significantly reduce storage and data manipulation costs. Yet, with these storage methodologies come new challenges in the visualization of temporally adaptive datasets. Wavelet compressed… (More)
