Hi.
Is there a preferred way to get a list if networks, for which IRIS is
the "authoritative" data center? If I try with the Station-WS I get many
networks that do *not* belong to IRIS. Even with "matchtimeseries".

Thanks in advance.

    Hi Javier-

    Give the new FDSN fedcatalog service a try. By default, it removes overlaps of the same station data between data centers, displaying the primary provider for each. This can be adjusted with the includeoverlaps option. Since it defaults to false, this example shows just the primary stations.

    http://service.iris.edu/irisws/fedcatalog/1/query?net=GE&cha=BHZ&start=2008-09-01&end=2009-01-01

    The output from this service can be sent by POST to each data center providing fdsn/station and fdsn/dataselect services to access data conveniently.

    If you add a '&format=text' term, you can get more detailed metadata about each station.

    Since you asked about getting a list of networks, that may blur the lines a bit if IRIS has some stations it is considered primary for but (as shown with GE 2008-2009) a majority of the stations are primary with GFZ. I don't think there is an abbreviated representation of just network codes as a result, but you could do some parsing to break down the network codes if that's what you are after.

    More documentation can be found here: http://service.iris.edu/irisws/fedcatalog/1/

      Dear Rob,

      thanks for your answer. The problem is that the fedcatalog will give me
      exactly the wrong answer. If I ask for GE, everyone knows that this is
      archived at GEOFON(GFZ) and not somewhere else. It's good or could be
      useful to have an idea of other replicas, but for me it's mandatory to
      know who has the "main/original" copy.

      In any case, I appreciate a lot your suggestion.

      Thanks!

      Javier

        Dear Rob,

        I think I was not so clear in my answer and I don't want to be
        misunderstood. :-(

        The fedcatalog provides valuable and detailed information about replicas
        of the waveforms at the *channel* level, but it's not exactly what I was
        looking for.

        I'm interested in finding the authoritative datacenter for a particular
        network, what is conceptually different from location of replicas for
        particular channels. It's only in that context that I meant the answer
        from the fedcatalog would be wrong for my purpose.

        And of course, the idea is to know if there is an *automatic* way to
        discover what I need. Something that does not need the interaction from
        a human.

        I hope I could clarified this now.

        Again, thanks a lot for your answer!

        Javier

          Hello Javier, the concept of primary or authoritative data center is still something the FDSN is discussing. In fact the meeting at EGU will be taking the first step in this direction.

          Right now what IRIS has done is come up with a concept of federation from an IRIS perspective, what is needed is the concept from the FDSN which does not yet exist.
          Note that we call this the IRIS federated catalogue not the FDSN catalogue…. for that reason

          Cheers
