Active Message Threads for October 2011

I suppose I can fix it on the client side, but if the time window has
the same start and end day, no result is returned even if there really
was a channel in existence on part of that day. For example, the start
time for PAULI is <StartDate>2011-04-26T15:00:00</StartDate>, but
asking for the resp for one of its channels on that day with this URL
http://www.iris.edu/ws/station/query?net=CO&sta=PAULI&loc=00&chan=HHZ&timewindow=2011-04-26,2011-04-26&level=resp
gives:

Hi
For the resp level output from this URL:
http://www.iris.edu/ws/station/query?net=CO&sta=PAULI&loc=00&chan=HHN&level=resp
The Stage 2 response consists of just a <StageSensitivity> which has a
empty <GainUnits/> element. All of the other stages also have
sensitivities with the <GainUnit> but it is filled in with the same
value as the <InputUnits> of the stage.
<Response stage="2">
<StageSensitivity>
<SensitivityValue>1</SensitivityValue>
<GainUnits/>
<Frequency>.05</Frequency…

Re: GainUnits in StageSensitivity - Yazan Suleiman - 2011-10-28 15:59:57
HI
Time has gotten away from me, but I will try and read the new schema
more carefully soon and send in any more comments I have. But do have
three so far.
First is, please consider some sort of versioning in the schema. I
believe I posted a comment some time back about this, but for an xml
schema to be useful, you need to be able to pair an instance XML
document with the schema that it uses. My understanding is that this
is usually accomplished by adding a version of some kind to the
namespa…

Re: some comments on new staitonXML - Shang-Lin Chen - 2011-10-27 22:43:58
Hi
So two of the three stationXML examples on the SCEC website are
invalid. IMHO, a lot of the value of having a schema is lost if it
isn't used for validation, at least occasionally.
I have to say that writing code to deal with StationXML is made more
complicated than it needs to be when the documentation, the xschema,
and the examples+web services are all slightly incompatible. It would
be really nice if the agreement between these three could be tightened
up a bit, especially if stationxml…

Hi
Small issue, but here is another place where the documentation and the
schema don't line up.
<!-- Positive integers used as counters for stage numbers, component
numbers, etc. -->
<xs:simpleType name="CounterType">
<xs:restriction base="xs:integer">
<xs:minInclusive value="0"/>
</xs:restriction>
</xs:simpleType>
The docs seems to indicate that CounterType should start with 1 but
the schema says it starts with 0. The use in the stage number of a
response, using stage=0 to denote …

Hi
I am looking into pulling responses via the stationXML XML web
service, and am getting a <Response> that contains only a
<StageSensitiviy> but the docs in the xschema it should have one of
<PolesZeros>, <Coefficients>, etc. From the xschema:
<xs:documentation>Choose one of these responses. There should be one
response per stage.</xs:documentation>
</xs:annotation>
An example is <Response stage="2"> in:

Re: stationXML and responses - Philip Crotwell - 2011-10-21 17:21:06
HI
The "Channel" field in the station URL builder puts "cha" in the query
parameters, but from the docs it should be "chan". The result is that
if you use the query builder and specify "BHZ" you end up getting all
active channels at that station instead of just the one you wanted.
For example:
http://www.iris.edu/ws/station/query?net=II&sta=AAK&loc=00&cha=BH1&timewindow=1990-11-30%2C1990-11-30&level=resp

Re: station URL builder - Yazan Suleiman - 2011-10-21 17:18:32
Hi
The schema says that the <Gain> element within a channel <Epoch>
"Corresponds to SEED blockette 58 for stage 0." but the xml from the
web service does not include a <Gain> element and instead includes a
<Response stage="0"> that only contains a <StageSensitivity>. Seems
like using stage=0 is a SEED convention that really shouldn't be used
in stationXML???
This section of StationXML also seems pretty confusing as there are 4
different places you could put the overall gain,
<InstrumentSensit…

Re: Response stage 0 vs Gain in stationXML - Philip Crotwell - 2011-10-20 19:00:57

Hello web service users,
The DMC's primary storage system that contains the archive will be undergoing maintenance today at 2:00pm Pacific time. We expect the maintenance to take no longer than 30 minutes.
This means that the web services that return time series data will not be able to return anything from the archive, data from the real-time buffers should remain accessible. All other services should not be effected.
Thanks for your patience,
IRIS DMC

Hi
This URL generates a large number of duplicate <stationEpoch> elements
for each station. Oddly, if anything, including a *, is put in the
"sta" query item, then the duplicate stationEpoch elements are not
there. Deleting the timewindow also removes the duplicate entries. Not
sure, but wonder if it is picking up a stationEpoch for each channel?
http://www.iris.edu/ws/station/query?net=II&timewindow=1997-06-07%2C2011-06-07&level=sta
thanks,
Philip

Hello web service users,
The DMC's database will be down for maintenance starting at 12:00pm Pacific time today. We anticipate no more than an hour of down time.
During this time most of the DMC's web services will not work. We will post another message when the services are back in working order.

Hello webservice users,
The DMC is pleased to announce the release of the ws-event webservice (version 1.1.0).
http://www.iris.edu/ws/event/
The event web service returns event information in the QuakeML format (schema 1.2 RC3). As with most of our other webservices, ws-event accepts simple HTTP GET query parameters. Events may be selected based on location, time, catalog, contributor and internal identifiers.
The IRIS DMC receives earthquake location and magnitude information primarily fr…
