  skos:definition """The Federation of Digital Broad-Band Seismograph Networks (FDSN)
is a global organization. Its membership is comprised of groups
responsible for the installation and maintenance of broad-band
seismographs either within their geographic borders or
globally. Membership in the FDSN is open to all organizations
that operate more than one broadband station. Members agree to
coordinate station siting and provide free and open access to
their data. This cooperation helps scientists all over the world
to further the advancement of earth science and particularly the
study of global seismic activity.

The FDSN goals related to station siting and instrumentation are
to provide stations with good geographic distribution, recording
data with 24 bits of resolution in continuous time series with at
least a 20 sample per second sampling rate. The FDSN was also
instrumental in development of a universal standard for
distribution of broadband waveform data and related parametric
information. The Standard for Exchange of Earthquake DATA (SEED)
format is the result of that effort.
