Abstract:

Visualizing and analyzing the explosive datasets coming from observation and simulation in the geosciences is becoming great challenge. Using parallel visualization technique to visualize the large-scale geosciences data is an effective solution. We discuss the usage of large-scale data parallel visualization in the geosciences in the paper. We firstly introduce the several parts of large-scale data parallel visualization, then characterize the features of large-scale data of geosciences, at last, we discuss the usage of parallel visualization of large-scale data in the visualizing simulation results of mantle convection, seismic wave propagation and tsunami.

Key words: Large-scale Data, Parallel Visualization, Mantle Convection, Seismic Wave Propagation, Tsunami
