A Scalable System for Visual Analysis of Ocean Data
This provides oceanographers with a more efficient tool for visual analysis of large-scale ocean data, though it is incremental as it builds on existing visualization frameworks.
The authors tackled the challenge of visualizing complex ocean data by developing pyParaOcean, a scalable system that integrates with ParaView to enable interactive analysis, as demonstrated in a case study on the Bay of Bengal with scaling studies showing efficiency improvements.
Oceanographers rely on visual analysis to interpret model simulations, identify events and phenomena, and track dynamic ocean processes. The ever increasing resolution and complexity of ocean data due to its dynamic nature and multivariate relationships demands a scalable and adaptable visualization tool for interactive exploration. We introduce pyParaOcean, a scalable and interactive visualization system designed specifically for ocean data analysis. pyParaOcean offers specialized modules for common oceanographic analysis tasks, including eddy identification and salinity movement tracking. These modules seamlessly integrate with ParaView as filters, ensuring a user-friendly and easy-to-use system while leveraging the parallelization capabilities of ParaView and a plethora of inbuilt general-purpose visualization functionalities. The creation of an auxiliary dataset stored as a Cinema database helps address I/O and network bandwidth bottlenecks while supporting the generation of quick overview visualizations. We present a case study on the Bay of Bengal (BoB) to demonstrate the utility of the system and scaling studies to evaluate the efficiency of the system.
