Querying and Visualizing Gridded Datasets for e-Science

We demonstrate a web service and client application for querying and visualizing datasets defined over arbitrary topological grids. Such gridded datasets are produced by Earth science simulations, 2D and 3D visualization software, and image processing systems. Existing systems for manipulating gridded datasets capture only simple grids or do not support remote access. We exercise a novel data model by using it to build a web-enabled visualization system. We show that complex visualizations, including animations, can be expressed using our data model and associated algebra. Further, we demonstrate a standards-based, service-oriented architecture for processing the algebra expressions and returning results over the web.
