6. JPL Status Report, SCIGN Annual Meeting, 4/26/2004 REASoN Goals Apply modern IT methodology within SCIGN to: –Produce and disseminate higher-level data products to a larger community Scientists Government agencies (Federal, State, and Local) Surveyors GIS professionals Product levels adopted by PBO

7. JPL Status Report, SCIGN Annual Meeting, 4/26/2004 REASoN Goals Build on current capabilities within SCIGN for data archiving, information systems, and data analysis to disseminate the following products: –Geodetic position time series –Crustal motion models –Strain rate maps –Geologic fault models –Near-real-time earthquake response information –Geodetic reference systems for precise GIS and surveying Improve capabilities in –Archiving –End-user interfaces –Delivery mechanisms –Data modeling Open source project based on a redundant, multi-tiered “Virtual Archive” for GPS applications.

8. JPL Status Report, SCIGN Annual Meeting, 4/26/2004 How we are organized Around Four systems –Product Input Seamless Archive Web services –GPS Data Processing GAMIT and GIPSY –Product Generation QOCA Based –Product Output Virtual Archive Web services –Meta data –Products Plus two NASA requirements –NASA SEEDs participation Standards Working Group –Open Source Project Virtual Archive

9. JPL Status Report, SCIGN Annual Meeting, 4/26/2004 A High Level Requirement Need Processing centers and processes use the same input data Goal All processing retrieves data from a common source Objective Seamless Archive Web services Pull data at time of analysis Push results into archive Pull products from archive for distribution
