Information Visualization

Description

This project is aimed at building interactive models to achieve (a) multivariate, time-series data visualization of a multi-component hydrological system, and (b) time-series data of flows in a localized region, for statistical analysis. Similar to the previous work, our paradigms are a combination of information visualization and scientific visualization methods, for example, two-dimensional and three-dimensional glyphs, focus+context methods, representation of multiple parameters, color-mapping, color matrices, and radar plots. We have developed two visualization systems, with varying scopes, to study the water bodies in Northern California. On a global scale, we focus on the reservoir-riverdelta system in Northern California, and on a local scale, we focus on the Sacramento-San Joaquin Delta. The motivation in the former is to develop a tool to see a global behavior in multiple parameters, and study their interplay with flow, on a temporal basis. The motivation in the latter is to develop a statistical analyzer to microscopically analyze variations of flow in the Delta over time. Further information is available in the detailed project description.
