  1. Giovanni 3: From Concept to Reality GO-ESSP 2008 Seattle, WA Jianfu Pan*, GES DISC/NASA jianfu.pan-1@nasa.gov *Affiliation: Adnet Systems, Inc.

  2. The Goal • Analyze, visualize, access • Data of any type and from anywhere • Intuitively, flexibly, professionally An infrastructure to integrate data and services

  3. The Simpler Is Better • No software to install • No need to learn data formats • No need to do programming • No need to download large amount of data

  4. Core technologies • Web services • Workflow (WS-BPEL, sciflo, Apache ODE) • OpenGIS (WCS, WMS) • Math ML • Presentation/content • Function extension • Parse and execution

  12. The Future • MyGiovanni • Service sharing • Semantic Giovanni

  13. Conclusion • An intuitive data analysis/visualization tool • Complexity hidden from users • Highly customizable • More than a dozen instances in operation • Continue to expand capabilities

  14. Some operation stats • 21 instances • 193 data products • 17 papers published since 2007

  15. Questions and Answers Thank you!
