Overview
  • Background
  • Portal development
  • Combined product
  • New IT Effort
  • Web service development
  • REASoN Data Portal/GPS Explorer
  • Geophysical Resource Web Services (GRWS)

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

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

5
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

GRWS Now serving
  1. Over 10 years of data for 500 western US CGPS
    stations.
  2. Dynamic, web-accessible source for vetted GPS
    solution input metadata in XML format.
  3. Rigorous weekly GPS combination using st_filter
    of data from (1) and metadata from (2).
  4. Sophisticated TimeSeries Applet with full suite
    of combination components from (3).
  5. Advanced online spatio-temporal visualization
    tool (SOMI) to be incorporated into ongoing
    portal development.

19
GRWS Currently developing
  1. Additions to Service Oriented Architecture for
    combined GPS solution product delivery,
    registration, request retrieval
  2. Web-accessible components for portal development
  3. Prototype framework for GPS Explorer, a public
    portal for online GPS-related analysis, science,
    teaching and discovery
  4. Machinery to enable complete, on-demand
    re-processing
  5. Public, queryable project metrics and usage
    interface

21
GRWS Moving towards Full automation of...
  • Outlier removal
  • Quality reporting
  • Regional filtering
  • Spatial coherence detection
  • Integration with modeling databases (QuakeSIM)
  • Velocity strain map generation
  • Sub-daily and real-time solutions and the public
    release of GPS Explorer.

22
New NASA IT Effort
  • Merge three related projects under one frame work
    (2006-2008)
  • SCIGN-REASoN (2004-2008)
  • Combination, validation, archive, and delivery of
    high-level data products and data mining
    capabilities from space geodetic measurements,
    specifically continuous GPS (CPS) observations.
  • QuakeSim (2003-2006)
  • Development of linked Web service environments
    for supporting high performance models of crustal
    deformation from a variety of geophysical
    sensors, including GPS and seismic instruments.
  • SENH-Applications GPS/Seismic integration
    (2003-2005)
  • Development of a prototype real-time GPS/seismic
    displacement meter, for use by local agencies
    responsible for seismic hazard mitigation and
    monitoring of critical infrastructure.
