<h1>SeisComP FDSNWS DataSelect Web Service</h1>
<p>The dataselect Web service provides access to time series data in <a
href="http://www.iris.edu/data/miniseed.htm">miniSEED</a> format. The data may
be filtered e.g. by time, station and network parameters. The request type is
<em>HTTP-GET</em> and <em>HTTP-POST</em>. Please refer to
<a href="http://www.fdsn.org/webservices">http://www.fdsn.org/webservice</a>
for a complete service description.</p>

<b>No</b> trimming of miniSEED records to requested time window &mdash;
This FDSNWS implementation returns the records as available in its data
source, e.g., SDS archive. It is guaranteed that the requested time range
is within the returned data (if available in the archive) but not that it
is exactly the requested time range. FDSNWS does not trim and therefore
re-encode miniSEED records. The rationale for that is that miniSEED
records are probably further distributed and stored in other archives and
we do not see the point in modifying them. Furthermore we do not want to
increase the load on the web server with that extra processing step.
