FDSNWS Dataselect Webservice Implementation

The FDSNWS-Dataselect service provides access to raw waveform data for requested channels and time windows. Data can be selected using SEED stream identifiers (network, station, location, and channel) in addition to a starttime and endtime. Waveform data are returned in mSEED format.


This service is an implementation of the FDSN web service specification version 1. For a complete service description refer to fdsn.org/webservices.

Making a GET request

Waveform data can be downloaded from ORFEUS EIDA using GET request by contacting the webservice address with specific request options inside the URL query. Webservice requests are generally formatted as follows:


Example! Copy the following URL


This request will return mSEED data from station NL.HGN between 2017-01-01T00:00:00 and 2017-01-01T00:01:00 from ORFEUS Data Center.
