What is Cyber Infra-structure (CI)?
“… new research environments that support advanced (spatial) data acquisition, data storage, (spatial) data management, (spatial) data integration, (spatial) data mining, (spatial) data visualization and other (spatial) computing and (spatial) information processing services over the Internet.”
“… technological solution to the problem of efficiently connecting data, computers, and people with the goal of enabling derivation of novel scientific theories and knowledge.”
Q? Is Geography enabling technology or domain science ?
NSF CI Vision 2007, NSF Blue Ribbon Committee 2003, …(a) HPC(b) Data, e.g. DataNet, InterOP( c) Virtual Organization, e.g. VOS(d) Learning Workforce Development
Related initiatives include CDI
2A. CI Research & Development : Spatial Databases
only in old plan
Only in new plan
In both plans
Evacutation Route Planning
Parallelize Range Queries
Storing graphs in disk blocksShortest Paths
2B. CI Research & Development : Spatial Data Mining
Nest locations Distance to open water
Vegetation durability Water depth
Location prediction: nesting sites Spatial outliers: sensor (#9) on I-35
Co-location Patterns Tele connections
3a. Vision and plan you have on CI
Advance Domain Science Computational methods = Third leg of modern science (w/ theory and experiments)
Bring to life theoretical models of phenomena too complex, costly, hazardous, vast or
small for experiments
Advance C.I. , e.g. Spatial Databases, Spatial Data Mining
• Ex. El Nino affects climate at many land locations
Global Influence of El Nino during the Northern Hemisphere Winter(D: Dry, W: Warm, R: Rainfall)
Average Monthly Temperature
(Courtsey: NASA, Prof. V. Kumar)
4a. What role do you see for the new CI Specialty Group?
Build bridge between GIS and CI communitiesWhy challenges/opportunities does CI provide to Geography researchers ?Why challenges/opportunities does Geography provide to CI researchers ?
NSF Programs seeking input to shape CDI and other OCI programs
Computing Research Associates: RFP for grants to organize Visioning Workshops
Q? Should AAG/CI group engage in these initiatives ?- Geography as an enabling technology for other domains, e.g. Epidemiology- Unique CI needs, e.g. Spatio-temporal Google Earth
Computational Challenge: Computing determinant of a very large matrix in the Maximum Likelihood Function:
