fdsnws_scripts is a collection of next generation distributed data request tools that are based on FDSN web services and the EIDA routing service.

You may use these tools to request

• seismic waveform data, as mini-SEED, using the fdsnws-dataselect web service,

• seismic metadata, as FDSN Station XML, using the fdsnws-station web service.

• availability information, as JSON or POST format, using the fdsnws-availability web service.

There are four tools here:

• fdsnws_fetch can request waveform data or metadata, from multiple data centres (access points) with a single command. It does this using the EIDA routing service to discover which data centre(s) holds the data requested.

• fdsnws2sds supports requests for larger amounts of data, saving it in an SDS tree-like file system structure (the SeisComP Data Structure). SDS is defined here.

• fdsnws2seed provides full SEED and dataless SEED using EIDA FDSN web services. Modern applications should use FDSN StationXML instead of SEED.

• fdsnavail lets the user interact with the new FDSN availability web service and compare to their local data holdings to find missing data.
