Hello Web Service users, On Tuesday April 17th the DMC will be installing new load balancers which will effect access to all of the DMC's web services. Work is expected to begin at 2:00pm Pacific (21:00 UTC). Our services will be unreachable for some number of minutes, after which they will likely be intermittent for up to a couple of hours following the switch. We will send a follow up notification when the access is stable again. Apologies for the inconvenience this will cause, unfort... [more]

Hello FetchBulkData users, The FetchBulkData perl script has been updated to fix a problem introduced when parsing the XML for stations that contain channel comments. This only effects the use of the metadata file written by the script, in particular if you are using mseed2sac with the metadata file you will want the new version. New release is available here: http://www.iris.edu/ws/wsclients/ with more overview information here: http://www.iris.edu/ws/wsclients/fetchclients.htm regard... [more]

Hello MATLAB users, The IRIS-DMC is pleased to announce you can now use MATLAB® to access data and information at the DMC. We have created an .m file (irisFetch.m) that contains functions needed to access station metadata, event metadata, and seismic traces. The retrieved data is placed directly into a MATLAB variable and is available for immediate use, no knowledge of web services or internal DMC formats (SEED or XML) is required. Using the irisFetch.m file, you will be able to retrieve: ... [more]

The DMC is pleased to announce the new IRIS Java Web Service Library (IRIS-WS Library). This Java API allows you to access DMC data directly from within your programs. It constructs web service calls based on criteria you define, and then accesses the services behind the scenes. Information is retrieved as java objects that are available for immediate manipulation, bypassing traditional “save to disk, reload into my program, and then parse the data format” steps. No knowledge of web servi... [more]

Hi Is there any interest by the DMC in open sourcing the code to your web services? In particular, I am thinking about putting a compatible web service on some of my databases (likely dataselect, maybe stationxml) and it would be really, really nice if I didn't have to implement them from scratch. And moreover, if many systems implement the same web service then it becomes much more useful as clients can then be easily reused. Thanks, Philip

Hi. While testing the updated station web service, I found that the following returns invalid XML in both the production and beta versions of the service: http://www.iris.edu/wsbeta/station/query?updatedafter=2012-04-01&level=resp&net=NM&sta=PENM&timewindow=1999-07-02,2599-12-31 All of the stations I tried in net NM returned errors. Thanks! -- John

This service returns information for stations belonging to virtual networks, the station details may be returned in XML, comma-separated values (CSV), or MS-Excel (XLS) format based on the value of the output parameter. Virtual networks represent groups of stations and/or seismic networks organized under umbrella organizations or initiatives, rather than traditional seismic networks. These... [more]
