1. 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)

2. Spatialization Tranformation from multidimensional non- geographic 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

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

4. Simultaneous Overlay of Multiple Cluster Levels to Support Domain Comprehension

5. Spatialization “Landscapes” with Cluster Validation

6. “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, GeoComp

7. 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

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