Visualizing Hurricane Katrina: large data management, rendering and display challenges

The onslaught of Hurricane Katrina has highlighted the need for effective information display. Visualization of geoscientific data faces challenges of size, integration and representation. Rendering methods need to cope with the surge of data due to advancements in acquisition techniques and computing power. Moreover, data stemming from different application communities are not compatible a-priori. Holistic representations are important to communicate the causes and impact of natural catastrophes to the scientists themselves, decision-makers and the general public. To address these issues, we have developed efficient data layout mechanisms to ensure fast and uniform access to diverse data. We apply effective rendering techniques that intuitively and interactively convey the phenomena. Finally, we discuss the use of high-resolution displays connected via high-speed networks to support collaboration. These components establish a framework for application in hurricane research, coastal modeling and beyond.
