Data Sources Observed: Sensors, experiments, etc… Simulated: Weather, earthquakes, etc… Data Attributes Time varying Multivariate Heterogeneous 2

Problems How to verify and validate ? How to analyze and gain scientific insight ? How to share information among experts and others? 3

Understanding Data Large amount of numbers don’t make much sense to humans Visual information can encode large amount of numbers to gain insight Low Bandwidth High Bandwidth 4

Quest for Visual Representation Desirable Attributes Intuitive Highlights feature of interest Color: Perceptual or Rainbow style? 5

Dirty Data Issues Data Formats Data Translation Data transfer and replication between archival and active file systems Data larger than available memory 17

Lessons Learned (TeraShake) In the north-westward propagating rupture scenario the wave propagation is strongly guided toward the Los Angeles basin after leaving the San Andreas Fault (unexpected) The sediment filled basin acts as an amplification source for trapped waves. A Strong amplification is observed in the LA basin long after the initial rupture (unexpected) Contiguous basins act as energy channels, enhancing ground motion in parts of the San Gabriel and Los Angeles basins. Identification of regions of particularly strong shaking Validation of input rupture model and instability identification Observation of star burst patterns in the Spectral Amplification maps (unexpected) 18

Visualization Issues Domain knowledge Multivariate data representation design Temporal coherence Precision Loss (compression, etc…) Interaction vs. batch visualization Perceptual Issues Personal Bias (author & viewer) 19

“Information is infinite” Information overload Can’t win Can’t break even Can’t get out of the game Can visual representation help? Think Petascale Data Analysis Joseph Kielman Science Advisor Dept. of Homeland Security Comments at VAST2006 Capstone 20
