What is EarthScope?

• A nationwide program to ..
• Explore the structure and evolution of the North
  American continent
• Understand processes that cause earthquakes and
  volcanic eruptions

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

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
