Mseed data format

Mseed data format-SWC retrieves data in miniSEED format (no instrument response metadata) Instrument response metadata can be retrieved through web services as dataless seed (readable with rdseed), resp file format, or station XML Full network IR metadata is available in our network directoriesThe SeedLink protocol is a robust data transmission intended for use on the Internet or private circuits that support TCP /IP The protocol is robust in that clients may disconnect and reconnect without losing data, in other words transmissions may be resumed as long as the data still exist in the servers buffer
