By Tim Ahern Program Manager, IRIS Data Management System Secretary, FDSN 9-11 May 2007 Kiel, Germany The International Federation of Digital Seismographic Networks (FDSN): Building International Collaborations

The FDSN The History of the FDSN FDSN’s Role in International Coordination Membership Goals FDSN Network Data Exchange at many Levels Real Time Data Exchange Distribution of Data Coordination at many scales using standards Overview of the Talk

Raison d’etre In the early 1980s broadband seismology was in its infancy The scientific problem was global Costs were high No one country could build a global network by itself The FDSN was formed to address the above situation Bottoms Up Lead by leaders in seismology This should sound familiar

Coordination of the siting of seismic stations 2000 km spacing in the FDSN Backbone Higher density Regional Networks Establishment of standards in instrumentation 24 bit, 20 sample per second continuous Broadband (World Wide Long Period and World Wide Short Period channels can be derived from a single a stream) Establishment of Data Exchange Formats S.E.E.D. Standard for the Exchange of Earthquake Data Providing Open Access to Data The FDSN Network Promotes Near Real time data access Access to Quality Controlled Data with minimum delay FDSN Goals

Bottoms up is usually good in drinking and in building organizations Focus on a few key and active players that can really make things happen Data Sharing in Real Time and without restrictions is optimal But develop methods to provide credit Interoperabilty with other Domains is increasingly important Web services and web mapping services Some Thoughts
