Formats

Dataless SEED

Dataless SEED is a subset of the SEED data format, and includes instrument responses, instrument coordinates, compression type, etc.. A dataless volume is commonly used to populate a metadata database or in combination with MiniSEED to convert time series to an alternate format such as full SEED (using the IRIS DMC’s rdseed software).

Station XML

A modern alternative to dataless SEED volumes to exchange seismological metadata is the FDSN’s StationXML schema.
