Transcript Seafloor Mapping and GIS for the FBNMS

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, GeoComp
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”?
