obspy.xseed - Dataless SEED, RESP and XML-SEED read and write support for ObsPy¶
XML-SEED was introduced by Tsuboi, Tromp and Komatitsch (2004), it is a XML representation of Dataless SEED. This module contains converters from Dataless SEED to XML-SEED and vice versa as well as a converter from Dataless SEED to RESP files. The xseed module is tested against the complete ORFEUS Dataless SEED archive, the IRIS (US) Dataless SEED archive and against ArcLink response requests.

Allocate a Parser object and read/write¶
>>> from obspy.xseed import Parser >>> sp = Parser("/path/to/dataless.seed.BW_FURT") >>> sp.writeXSEED("dataless.seed.BW_RJOB.xml")
The lines above will convert Dataless SEED, e.g.:
000001V 010009402.3121970,001,00:00:00.0000~2038,001,00:00:00.0000~ 2009,037,04:32:41.0000~BayernNetz~~0110032002RJOB 000003RJOB 000008 ...
to the XML-SEED representation, e.g.:
<?xml version='1.0' encoding='utf-8'?> <xseed version="1.0"> <volume_index_control_header> <volume_identifier blockette="010"> <version_of_format>2.4</version_of_format> <logical_record_length>12</logical_record_length> <beginning_time>1970-01-01T00:00:00</beginning_time> <end_time>2038-01-01T00:00:00</end_time> <volume_time>2009-02-06T04:32:41</volume_time> <originating_organization>BayernNetz</originating_organization> ...
>>> sp.writeRESP(folder="BW_FURT", zipped=False)
The Parser Object¶
SEED files as well as its derived format XML-SEED will be parsed in a Parser structure.
SEED volumes have four different volume types:
- Volume Index Control Headers
- Abbreviation Dictionary Control Headers
- Station Control Headers
- Time Span Control Headers (currently not supported by ObsPy. Some dummy headers will be written in case they are needed by SEED/XSEED conventions.)
After parsing a SEED or XML-SEED file the Blockette objects for each volume will be stored in the attributes``Parser.volume``, Parser.abbreviations and Parser.stations. Each item is a list of all related Blockettes and Parser.stations is a list of stations which contains all related Blockettes.
