  1. IT as a Tool to Provide Seamless Access to Diverse Data Sets By Tim Ahern Program Manager Data Management System The IRIS Consortium

  2. Information Technology at IRIS • Diverse Data Holdings of IRIS • Real Time Communications Systems • Streaming data • Automated Quality Assurance • Data Mining Opportunities • Distributed Technologies • CORBA • Web Services

  3. Types of Data Managed at the IRIS DMC 25 distinct data types

  4. Seismological Broadband Seismometers Strong Motion Buildings Structures Free Field Geophones Hydrophones Geophysical Magnetotelluric Magnetometer Electric Field Strainmeter dilatational tensor Tidal Pendulum Gravimeter conventional superconducting Tiltmeter Creep Meters Meteorological Wind Speed Wind Direction Temperature Humidity Rain Gauge Solar Radiaton Insolation/Pyranometer Microbarograph Relative/Absolute Infrasound Microphones Hydrological Water Current Depth Temperature Water Level EarthScope USArray PBO SAFOD Types of Sensor Data IRIS Manages:25 distinct types

  5. More than 5,000 seismic stations have data available through the IRIS DMC

  6. The Time Span of IRIS Data Temporary Networks 1986 - current Permanent Networks 1970 - current Targets of Opportunity 1966 - current

  7. Shipments from the IRIS DMC:A very active archive 220,000 customized shipments 35,000 on-line shipments 10 terabytes of observational data 0.5 billion seismograms (16 per second)

  8. Telemetry Data Reception and Distributionin Real Time Improved quality with reduced costs

  10. Automated Quality Control

  11. Distributed Data Access CORBA Web Services

  12. Global Earth Observation System of Systems (GEOSS) • GEOSS 10 Year Reference Document (p. 135) • Common Object Request Broker Architecture (CORBA) • Web Services Definition Language (WSDL) • Electronic Business Extensible Markup Language (ebXML) • Unified Modeling Language (UML) “GEOSS service definitions are to specify precisely the syntax and semantics of all data elements exchanged at the Service interface, and fully describe how systems interact at the interface. At present, the systems interoperating in GEOSS should use any one of four open standard ways to describe service interfaces: CORBA, Common Object Request Broker Architecture; WSDL, Web Services Definition Language; ebXML, electronic business Extensible Markup Language, or UML, Unified Modeling Language.”
