Proposed Topics
Multimedia and Visualization
Spatialization: Spatial Metaphors
Advancing Web GIS
VR and Teleimmersion (moved to GIS and Decision-Making)
1. What are the important
-research issues?
-research questions?
2. WHY are they important?
3. Relation to 10 + 4?
- Progress still needed?
- Language/Jargon different?
- Problem solved and therefore new challenge needed?
'Tulluch Criteria'
1. Important, Meaningful, Valuable?
2. Cutting Edge, Hot?
3. UCGIS members can/want to pursue
4. UCGIS benefits from promoting the challenges?
e.g., Grad students picking up research challenges, research focuses/projects
1. What are the Important Research Issues?
Spatialization
a. lack of theoretical background--cognitively inadequate
b. computational efficiency improvements--often looks good on a web page but often breaks down computationally
Representing text documents with spatial metaphors:
Need computational assessment of algorithms for the process of spatialization
Move beyond the limits of MDS and Spring algorithms
InfoViz field is now dominated CS & Info Science, not much by geographers/cartographers
Text is often the data that are processed used but could use Imagery--Remote Sensing data, etc.
Could be used for 9/11 issues, such as breakdowns in intelligence
Research dollars are available from NIMA, DOD, etc.
User testing needed to examine the cognitive foundations of Spatialization
Cognitive user testing - does it really work like a map?
Related to KDD & DM, distributed, Ontology, Data Integration yet Visualization is the most related area.
Spatialization is already in the Viz White paper (+4)
This is an example of a GI Science outreach towards other fields: such as CS, Info Sciences, Library Sciences, Arts & Multimedia studies, entertainment industry
No underlying space - non-geographic, high dimension (1000+ dimensions!), so there is much room for GI scientists to contribute...
"Web GIS"
At OrSt looking at journal articles, reports, other documents related to marine protected area designation off Oregon Coast. Putting them into a geographic context for Information Access via ArcIMS
.
Info Access these documents through a web-GIS as well as mobile computing and LBS
Move beyond just linking docs and maps
Are there research issues from looking at maps using the web as the medium:
Performance issues; the web server
Data Models and Data Structures for web-based GIS; unique?
Could be an update to the distributing computing challenges
Related to spatialization, data archives, KDD & DM, collaborative work via the web--simultaneous uses of the web-based GIS, real-time data use, could help develop interactive and collaborative research from a distance--i.e., collaboration between Africa and WVU.
A Core Problem: what should a web-based GIS data model be and how is different from typical desktop GIS...
Discussion
Spatialization queries are similar to GIS queries, the differences tend to be differences in geometry and levels of interactivity.
Possibly think about web-based GIS as its own research challenge--considering its breadth and different aspects of interaction. An area for soliciting research dollars.
Many issues for web-based GIS so it doesn't become mixed under the other visualization topics.
Policy issues also need to be examined considering access to information from the web
Mobile & distributed could be part of the web-GIS topic, vice versa, etc...
The Distributed Computing paper is somewhat dated now, could possibly enhance this research areas with web GIS, and mobile, the OGC and standards/interoperability...
Increasing use of cell phones & LBS services hold promise
Possible collaboration with industry...US is behind in LBS
Web GIS could be under the Geocomputation Group or an research area could be comprised of web-GIS, LBS, cybergeography, mobile & distributed, OGC, VR, performance issues, etc. as an unnamed research area...suggestions?
Multidimensional GIS?
Yet, don't want to eliminate the spatialization---geographic approach to handling non-geographic data, still distinct from the issues of KDD
Possibly non-geographic GI science, very challenging working in n-dimensions, adding the cartographic processes for representation
Could possibly be related to spatial autocorrelation and scale issues....
Might want to also add qualitative GIS...
VR & Tele are still visualization challenges
Is this issue in spatialization an issue of transformation and also visualization issues
The research question: if they are spatializations the computational elements are more related to KDD in terms of spatializations...
Geographers would want to be on the wave of Info Viz and scientific generalization generally.
Summary
1. Spatialization
as a research topic to the big group---lets see what the larger group feels about having spatialization as a research group. But if it's voted down; add to another group.
Can you take these to Congress as a research group?
2. Geographic visualization will remain, enhanced in part by Spatialization, "Web GIS", and VR and Teleimmersion
3. Distributed GIS.
CyberGIS- the summary of mobile, distributed, web & mobile GIS.
Vs. geocomputation--, others: telegeoprocessing, pervasive, distributed GIS?
Faciliator, Dawn Wright
Notetaker, Chris Badurek
Addendum:
Research Plenary - June 28, 2002
Groups that made connections to us:
Geographic Data Mining and Knowledge Discovery - strong linkages to visualization and spatialization
Dynamic and Intelligent GIS - intelligent GIS tied in a small way to web GIS via SDSU topic on intelligent (smart) GIServices (web-based mapping facilities, real-time GIS analysis tools via web, etc.)
