eGY Workshop 2008, Boulder, CO

A nationwide program to …..• Explore the structure and evolution of the North

American continent• Understand processes that cause earthquakes and

volcanic eruptions

What is EarthScope?

Drillhole across San Andreas Fault875 GPS Instruments175 Borehole Strainmeters5 Long-Baseline Laser Strainmeters400 Seismometers at 2,000 sites100 Permanent Seismometers

eGY Workshop 2008, Boulder, CO

Objective

• Provide a central search and data access capability for distributed USArray, PBO, and SAFOD data and data products– Data are distributed at IRIS (USArray), UNAVCO (PBO),

ICDP (SAFOD)

• Distributed implementation– A central Web service invokes Web services at each

location (WSDL/SOAP/XML), which search the local catalogs

• Distributed development– Software design and development by a distributed team

of developers, at SDSC, UNAVCO, IRIS, and ICDP– Leverage portal work already done for GEON

• Production portal to be ready by September 2008

Request Format

• Client can issue requests to– Get Station information– Get Data

• Request structure can specify:– TimeRange– DataClass– SpatialBounds– StationIdentifierFilter

• Schema of the EarthScope Data Portal request available at– http://schemas.earthscope.org/portal/0.4/esdp.wsdl

• Portal will provide ability to add datasets to a “data cart” and request download of data

Sample response to a data discovery query

eGY Workshop 2008, Boulder, CO

Milestones and Next Steps• Successful milestones

– Setup of portal environment at SDSC– Design of the API for station request– Testing of connectivity of the central portal site to all the

component sites (Station query used as an example)– Implementation of the GUI for station query– Design of the data discovery query

• Next steps– Implementation of the data discovery in progress– UI design and implementation for results of data discovery in

progress– Identify early “friendly” users * In progress!– Beta release– Production release in September 2008
