The KNMI FDSN Station Web Service provides access to network, station, channel and response metadata in FDSN Station XML format, as well as other useful formats, from the seismic network in The Netherlands. The metadata may be filtered e.g. by geographic region and time. Also, the information depth level is selectable. The request type is HTTP-GET.

Please refer to for a complete service description.

Feature notes

Feature notes regarding this implementation of the FDSN web service specification:

  • Back-end software: SeisComP4
  • includeavailability request parameter not implemented
  • updatedafter request parameter not implemented: The last modification time in SeisComP4 is tracked on the object level. If a child of an object is updated the update time is not propagated to all parents. In order to check if a station was updated all children must be evaluated recursively. This operation would be much too expensive.
  • matchtimeseries request parameter not implemented
  • Additional request parameters, effective only for xml output:
    • formatted: boolean, default: false
  • Additional values of request parameters:
    • format
      • standard: [xml, text]
      • additional: [fdsnxml (=xml), sc3ml]
      • default: xml
