  1. 4147 Cyber-Infrastructure (CI) Panel, AAG 2008 Panelist: Shashi ShekharMcKnight Distinguished Uninversity ProfessorUniversity of Minnesotawww.cs.umn.edu/~shekhar OutlineWhat is Cyber Infrastructure (CI) ?How CI relates to your research/development ?Vision and plan you have on CIWhat role do you see for the new CI Specialty Group? Any other information you want to share with the audience

  2. What is Cyber Infra-structure (CI)? 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 DevelopmentRelated initiatives include CDI “… 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 Geographyenabling technologyor domain science ? “… 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.”

  3. Shortest Paths Storing graphs in disk blocks Evacutation Route Planning only in old plan Only in new plan In both plans Parallelize Range Queries 2A. CI Research & Development : Spatial Databases

  4. Location prediction: nesting sites Spatial outliers: sensor (#9) on I-35 Nest locations Distance to open water Vegetation durability Water depth Co-location Patterns Tele connections 2B. CI Research & Development : Spatial Data Mining

  5. 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 • Characterize computational structure • Pattern families, interest measures, computational cost, … • Representations, data-structures, algorithms, … • Example: Evacuation Route Planning • Domain contribution: Walking > Driving for 1-mile radius areas • Computer Science: Scalable algorithm (i.e. CCRP) • Orders of magnitude faster than competition!

  6. Global Influence of El Nino during the Northern Hemisphere Winter (D: Dry, W: Warm, R: Rainfall) Average Monthly Temperature (Courtsey: NASA, Prof. V. Kumar) 3b. Vision: Towards Spatio-temporal • An Inconvenient Truth • Global datasets at many different timeslots • Wouldn’t it be a popular CI tool for scientists ? • Teleconnection • Find (land location, ocean location) pairs with correlated climate changes • Ex. El Nino affects climate at many land locations

  7. 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 programsComputing Research Associates: RFP for grants to organize Visioning WorkshopsQ? 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

  8. SDM: Opportunities for Computer Science Nest locations Distance to open water Vegetation durability Water depth

  9. Computational Challenges from Auto-correlation Computational Challenge: Computing determinant of a very large matrix in the Maximum Likelihood Function:

  10. 2. GeoInformatica: An Intl. Journal on Advances in Computer Science for GIS - Articles on CI advances motivated by GIS are welcome! Any other information you want to share with the audience 1. Encyclopedia of GIS, Springer, 2008 - Provides a computational perspective - Many articles relate to C.I. topics - Many libraries have paper and electronic copies!
