Hi all Since parsing units from a string can be tricky, I have gone through all of the networks available via the fdsnstation web service and pulled the units out. Luckily, there are only 41 distinct strings as unit names. To aid in converting values, I have put together a csv file with three columns: 1) unit name from the xml 2) my best guess at how to "SI" the unit (some are, um, nonstandard) 3) a "description" The only case I found of a unit name meaning two things in two different chann...

Hi Just a packaging question, the current jar file in both the direct download and in the src zip include the classes from dependencies (like log4j, javax.mail, etc). That is nice for someone that just wants to grab the jar and build a simple application on top of it, but can be problematic for a larger package that may already use dependencies like log4j. This will cause potential duplication and may be a bigger deal if the versions of the dependency libraries don't match. Obviously version... [more]

Hi It looks like the edu.iris.dmc.fdsn package is missing from both the source code distribution zip and from the online javadocs. Is that source in a separate download? ls src/edu/iris/dmc/ criteria extensions service ws event sacpz timeseries thanks Philip

Just to make sure I am doing this correctly... If I have a known channel start time, say 1995-03-21T17:16:00, then to limit the returned xml to be just the response for that single channel I should use endafter and endtime like this: http://service.iris.edu/fdsnws/station/1/query?network=IU&sta=ANMO&loc=--&cha=BHZ&endafter=1995-03-21T17:16:00&endtime=1995-03-21T17:16:00&level=response&nodata=404 In contrast, if I use starttime andendtime like this: http://service.iris.edu/fdsnws/station/1/q...

Web service developers, Version 2 of the IRIS Java Web Services access library is now available. This version is not backwards compatible with the 1.x release, primarily due to schema changes. While similar in usage to the 1.x releases, it is expected that developers will need to change code when adopting this new release level. Downloads and more available here: http://www.iris.edu/dms/nodes/dmc/software/downloads/IRIS-WS/2-0-0/ Features of this major new release: * This version uses... [more]

Hi http://service.iris.edu/fdsnws/station/1/query?channel=HHE&level=response&network=3A&station=L001 generates an invalid XML, the FIR has a <ResponseName> element but the schema says it should be a "Name" attribute. >From schema: <xs:attribute name="name" type="xs:string"> <xs:annotation> <xs:documentation>A name given to this filter. </xs:documentation> </xs:annotation> </xs:attribute> >From xml: <Stage number="3"> <FIR...

Hello web service users, The DMC has released an update to our fdsnws-event service (http://service.iris.edu/fdsnws/event/1/). This release also includes many changes to the internal workings of the service. Here is a list of some important updates: * The service now returns a hybrid result when a catalog is not specified. By default, the service returns events from the ISC catalog. The NEIC PDE catalog is used to return events that are too recent to appear in the ISC catalog. * If an ... [more]

I'm tired and might have goofed but here I asked for format=text but got QuakeML. Just a heads up, and I do realize it's beta. The non-beta one did give me text. ‎service.iris.edu/fdsnwsbeta/event/1/query?format=text&starttime=2010-01-01&limit=100

Yes, that fixed my problem using wget and led me to solve my underlying python problem. thanks for your help. Because it might be interesting, my old python bulkdataselect code: with open(input_file_name) as f: post_data = f.read() post_data = dict(selection=selection_data) request_obj = urllib2.Request(url=url_server, data=urllib.urlencode(post_data)) This did not work when switching endpoints, this did fine: with open(input_file_name) as f: post_data = f.read() request_obj = urllib2....
