FDSN Working III on Software Coordination
Minutes of Meeting June 14,
2002
Waikoloa, Hawaii
The
Software Working Group was well attended with 19 people attending. The primary purpose of this meeting was
to provide a forum where current software capabilities and systems could be
enumerated and as such promote sharing of resources across the FDSN community.
The
agenda focused in three areas
and
Chad
Trabant summarized the real time effort taking place within the European
Community, in the form of the MERIDIAN Project. At ORFEUS, the Antelope software is used to create a Virtual
European Broadband Seismic Network presently comprised of 43 real time stations
with latency of 10s of seconds.
They anticipate doubling the data flow rate within the next year by
incorporating more data from Spain, Portugal and France.
ORFEUS is
using Antelope for automated processing of the data to detect and locate events
and produce the corresponding waveform event volumes for distribution through
ORFEUS. They anticipate adding a
capability to export selected data to a finite number of locations from the
Antelope system in the future. The
may be adding an export ORB in the near future.
Trabant
summarized two applications of particular interest that were developed in
Europe. QuakeExplorer was written
by Anthony Lomax that allows one to browse WILBER events, both SPYDER¨ and
FARM. It can make data from many
sites in a seamless manner.
Manfred Baer from ETH has developed an application called
CollectWaves. It leverages autoDRM
technology to collect data from many data centers for specific events.
Joachim
Saul summarized the developments in the SEEDlink arena at GEOFON. This is a data relay and buffering
system that is miniSEED based. It
is robust and reliable. It has
gained significant acceptance in Europe and interest is being expressed in the
US.
Tim Ahern
summarized the IRIS BUD system. In
general this system leverages existing data delivery systems such as Earthworm
and Antelope to move data into a Uniform Format. Currently the BUD system at the DMC is receiving data from
600-700 stations every day with about 3,000-4,000 channels. IRIS is developing a variety of
data access methods from the BUD including LISS, WWW Wiggles applet,
FISSURES/DHI and a soon to be released autoDRM.
Harold
Bolton described the USGS LISS system.
It is a system that relies on a single connection between a data center
(ASL) and Quanterra stations. LISS
acts as a socket copier that allows multiple other centers to then tap into the
real time data feed. The
development of the LISS2 protocol is still taking place.
Dan
McNamara gave a presentation on the Earthworm system. The USNSN and regional networks within the United States use
it heavily. At the present time
Earthworm features web access tools, state of health information, wide
community support. It is being
considered for use by the Volcano Hazards programs. It has a variety of products such as Shakemap and it is
likely to be used as part of the ANSS.
Software
sharing was highlighted first by summarizing the various software modules that
are part of the ORFEUS software library.
More information can be found on the ORFEUS Web site. Ahern summarized applications and
utilities developed and supported by IRIS. They fall into roughly three different categories 1)
applications intended for end users, 2) applications intended for use by data
centers, and 3) new object-oriented based tools.
Ilya
Dricker of ISTI described the new EvalRESP, JEvalRESP and JPlotRESP
applications that ISTI developed for IRIS.
Rob Casey
summarized IRISÕ work on developing SEED classes for the SEED format. Tom Owens
asked about connectivity of these classes to databases through something like
FISSURES. Casey replied that this
was still in development.
Tom Owens
described work within FISSURES for the Standing Order for Data (SOD) in the
FISSURES/DHI system. It uses XML
to configure the system and it is used to formulate a request to a data center
for past present and future information.
The Global Earthquake Explorer (GEE) program is an IRIS E&O application
for use by teachers and perhaps in the future as a research tool.
Several
people reviewed other FISSURES tools.
Ahern described the FISSURES Visualization and Seismogram Extraction
(VASE) application. Casey
described the FISSURES implementation of WEED. Ahern reviewed JEvalRESP in its DHI mode. Ken Creager described the FISSURES
MATLAB interface.
The
meeting was adjourned after about two hours but the discussion was lively and a
large amount of information was shared.
