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.


fdsnws/dataselect/1/query

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:

http://webservice-address/label?options

Example! Copy the following URL

http://www.orfeus-eu.org/fdsnws/dataselect/1/query?network=NL&station=HGN&start=2017-01-01T00:00:00&end=2017-01-01T00:01:00

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.


Description of request parameters

The webservice supports the following parameters that can be used to fine-tune your request.

Wildcards and Lists

A question mark represents a single character, while an asterisk represents zero or more characters. Multiple items may also be retrieved using a comma separated list. SEED identifiers support wildcards and lists.

Time Formats

Times must be specified in the ISO-8601 format (e.g. 2017-01-01T00:00:00 or 2017-01-01) and are assumed to be in UTC.
