Multimedia/Visualization Breakout

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
Whats 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

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?
• --gt Pervasive GIS
