obspy.io.xseed - (X)SEED and RESP 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.
All files can be converted to ObsPy’s internal inventory objects at which point they can be written out to any format ObsPy supports. In the case of RESP files these are potentially incomplete as RESP files lack vital information like geographical coordinates.

Allocate a Parser object and read/write
>>> from obspy.io.xseed import Parser >>> sp = Parser("/path/to/dataless.seed.BW_FURT") >>> sp.write_xseed("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.write_resp(folder="BW_FURT", zipped=False)
The Parser Object
SEED files as well as its derived format XML-SEED will be
parsed in a
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.stations. Each item is a list of all
related Blockettes and
Parser.stations is a list of stations which contains
all related Blockettes.
