Overview • Background • Portal development • Combined product • New IT Effort • Web service development • REASoN Data Portal/GPS Explorer • Geophysical Resource Web Services (GRWS) http://reason.scign.org

SCIGN REASoN • NASA Funded project • Going forward • 2 years left • Goals • Generate higher level products from SCIGN data for use by the SCIGN community • Apply modern IT methodology within SCIGN to: • Produce and disseminate higher-level data products to a larger community of • Scientists • Government agencies (Federal, State, and Local) • Surveyors • GIS professionals • Build on current capabilities within SCIGN for data archiving, information systems, and data analysis to disseminate data 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. http://reason.scign.org

Focus • Portal development • Web service development for • Meta data • Data exchange • Combined solution generation • Coordinates from analysis centers • Time Series Calibrations • Time series “jumps” • Velocities (July ’06) • Strain map (early FY07) • Verification and validation of solutions • Product delivery • At web site using standard http pick-up • Via web services http://reason.scign.org

Portal development • Our philosophy • Produce a portal with products that are quantitatively publication quality that we would use for our own research. • Portlet environment • Map server • Interactively browsing and selecting meta-data • SOMI environment • for users to overlay temporal and spatial data sets on • Time series • Interactive exploration • Products • Unfiltered • Filtered • Raw Time series • JPL, SIO, PBO • Combined (JPL, SIO) • Time Series Calibrations • “Jump files” http://reason.scign.org
