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 (, 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)
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)
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 datasets.(More)
Web-cam is a decade-old technology, but it has received major impetus from recent advancements in both software and hardware. Here we report our experiences from using off-the -shelf web-cam tools for various configurations in collaborative ventures. They span from Macintosh to PC in hardware and IchatAV and SquidCam in software. We work from various(More)
This paper presents a new method for segmenting channel features from commonly noisy 3D seismic images. Anisotropic diffusion using Gaussian-smoothed first order structure tensors is conducted along the strata of seismic images in a way that filters across discontinuous regions from noise or faulting, while preserving channel edges. The eigenstructure of(More)
