MultimediaVisualization Breakout Spatialization Spatial Metaphors UCSB Advancing Web

Multimedia/Visualization Breakout • Spatialization: Spatial Metaphors – UCSB • Advancing Web GIS – Oregon State • Multimedia and Visualization – University of Oklahoma • VR and Teleimmersion (moved to GIS and Decision-Making)

Spatialization • Tranformation from multidimensional nongeographic to lower-D spatial • Information spaces – Cognitively inadequate • Do they really look like maps? Can they be understood? – Computationally inefficient – Generalization through semantic abstraction • “ 10 + 4” – Cognition, Extensions to Rep. , Scale – Geographic Visualization, Data Mining, Ontology

What’s the meaning of “scale” in non-geographic information visualization?

Simultaneous Overlay of Multiple Cluster Levels to Support Domain Comprehension

Spatialization “Landscapes” with Cluster Validation

“Web GIS” • Recent phenomenon in U. S. , “hot topic” • LBS in Europe • Should not just be transfer of 2 -D desktop to web – Outputs of spatialization - cognitive, computational – Data models, data structures different? – Performance measures, usability – Institutional issues/ethics of access, distribution – collaboratories • “ 10 + 4” – Distributed & Mobile Computing, Interoperability, Scale, GIS & Society, Data Integration – Geographic Visualization, Data Mining, Ontology, Geo. Comp

Conclusion 1 • Spatialization as a standalone challenge – Different from Geographic Viz challenge – GISci research applied to non-geographic data – Multidimensionality • e. g. , 1000 dimensions to 2 or 3 but no 2 -D reality to compare to – Information visualization – Cognitive, computational • If not standalone… – Should be explicit in DM/KD and Geographic Viz

Conclusion 2 • “Web GIS” standalone b/c so crosscutting? Timely? • Revisit and fold into Distributed & Mobile Computing to update that challenge to… “Distributed, Mobile, Location-Based, Cyber GIS”? “Telegeoprocessing”? --> Pervasive GIS
