Abstract
We describe our distributed systems research efforts to build the “cyberinfrastructure” components that constitute a geophysical Grid or more accurately a Grid of Grids Serviceoriented computing principles are used to build a distributed infrastructure of Web accessible components for accessing data and scientific applications Our data services fall into two major categories Archival databasebacked services based around Geographical Information System GIS standards from the Open Geospatial Consortium and streaming services that can be used to filter and route realtime data sources such as Global Positioning System data streams Execution support services include application execution management services and services for transferring remote files These data and execution service families are bound together through metadata information and workflow services for service orchestration Users may access the system through the QuakeSim scientific Web portal which is built using a portlet component approach
