Adaptable Seismic Data Format

Latest revision as of 17:25, 25 June 2024

The Adaptable Seismic Data Format (ASDF, not to be confused with the Advanced Scientific Data Format) is a format for storing seismic data as a replacement for SEED, although the authors claim that in a limited area of application SEED will continue to be useful^{[1], section 3.1}. It is based on HDF5, and has 4 main sections (implemented as HDF5 groups, except for the first, which is a single binary record):

• Non-time series data about seismic events, specified using an embedded QuakeML document^[2]
• Time series waveform data^[3]. Metadata about the station that produced the data is optionally stored in an embedded StationXML file
• "Auxiliary data", which holds anything miscellaneous^[4]
• Provenance of waveform^[3] or auxiliary^[4] data, specified with SEIS-PROV (a spun-off format)^[5]
