Thread: New versions of ws-bulkdataselect, ws-dataselect and ws-timeseries webservices

Hello webservice users,

The DMC has updated it's ws-bulkdataselect, ws-dataselect and ws-timeseries webservices

http://www.iris.edu/ws/bulkdataselect
http://www.iris.edu/ws/dataselect
http://www.iris.edu/ws/timeseries

User's of the DMC's FetchBulkData script should update to the latest version if you wish to select
data with microsecond resolution, older versions should continue to work as usual if microseconds
are not specified.

Users of the DMC's IRIS-WS library or MATLAB irisFetch.m are not effected.

Changes include:

-----------------------------------------
Microsecond time resolution
-----------------------------------------
Time limits may now include microsecond resolution, matching the resolution of the SEED data
in the DMC archive. Previous versions only supported millisecond time resolution.

This change allows selections to be specified at the sample level in all cases. For example,
all samples on day 2004-12-26 are selected with the following start and end times:

2004-12-26T00:00:00 2004-12-26T23:59:59.999999

This also allows users to break very large requests into smaller requests which can be
reassembled on the users end without generating gaps or overlaps.

--------------------------------------------------
Better handling of near realtime data
--------------------------------------------------
This change only effects ws-dataselect and ws-timeseries

Refreshing queries which are near realtime (i.e. cover time ranges close to the present time)
will more reliably result in newer and more current data sets being returned.
Previous versions held data cached for an hour or more.

-------------------------------------
Internal logging changes
-------------------------------------
We now better track returned http status codes to better help identify system problems

regards,
IRIS DMC web services team

  • Hi Bruce,

    Thanks for taking a look at the near realtime services. Unfortunately,
    none of my near realtime timesereis plot requests works now! If I
    request a plot for very near realtime (within minutes of realtime), I
    get two types of errors:

    Error 404: Not Found

    The Timeseries webservice was unable to find any data for your request.No data found for:AU,MTN,--,BHZ,2012-05-04T08:07:30.070,2012-05-04T08:07:30.070

    • Anthony:

      Sorry about that and thanks for the quick feedback.

      I'll take a look. It probably is related to the microsecond time resolution change.

    • New versions of ws-dataselect (1.8.3) and ws-timeseries (1.3.2) have been deployed to fix this problem.

      The problem only existed when the duration parameter was specified (rather than the endtime parameter).

      When the duration parameter was given, the starttime was effectively being set to the endtime and zero data
      was generated causing the data parser to fail.

      Once again, thanks for the quick feedback.

      Cheers,

      • Hi Bruce,

        Thanks very much for the quick fix - all seems to work fine now.

        Great!

        Ciao,

        Anthony

        Subject: Re: [webservices] Errors with Re: New versions of ws-bulkdataselect, ws-dataselect and ws-timeseries
        webservices

        New versions of ws-dataselect (1.8.3) and ws-timeseries (1.3.2) have
        been deployed to fix this problem.

        The problem only existed when the duration parameter was specified
        (rather than the endtime parameter).

        When the duration parameter was given, the starttime was effectively
        being set to the endtime and zero data
        was generated causing the data parser to fail.

        Once again, thanks for the quick feedback.

        Cheers,
        -Bruce


        Hi Bruce,

        Thanks for taking a look at the near realtime services.
        Unfortunately, none of my near realtime timesereis plot requests
        works now! If I request a plot for very near realtime (within
        minutes of realtime), I get two types of errors:

        Error 404: Not Found

        The Timeseries webservice was unable to find any data for your
        request.No data found
        for:AU,MTN,--,BHZ,2012-05-04T08:07:30.070,2012-05-04T08:07:30.070

        If I request a plot for data at around realtime - ~30min or
        earlier, I get the above errors or a blank plot.

        These requests are made using the BRB and HF channel links at:

        Sorry...

        Hello webservice users,

        The DMC has updated it's ws-bulkdataselect, ws-dataselect and
        ws-timeseries webservices


        http://www.iris.edu/ws/bulkdataselect
        http://www.iris.edu/ws/dataselect
        http://www.iris.edu/ws/timeseries


        User's of the DMC's FetchBulkData script should update to the
        latest version if you wish to select
        data with microsecond resolution, older versions should continue
        to work as usual if microseconds
        are not specified.

        Users of the DMC's IRIS-WS library or MATLAB irisFetch.m are not
        effected.

        Changes include:

        -----------------------------------------
        Microsecond time resolution
        -----------------------------------------
        Time limits may now include microsecond resolution, matching the
        resolution of the SEED data
        in the DMC archive. Previous versions only supported millisecond
        time resolution.

        This change allows selections to be specified at the sample level
        in all cases. For example,
        all samples on day 2004-12-26 are selected with the following
        start and end times:

        2004-12-26T00:00:00 2004-12-26T23:59:59.999999

        This also allows users to break very large requests into smaller
        requests which can be
        reassembled on the users end without generating gaps or overlaps.

        --------------------------------------------------
        Better handling of near realtime data
        --------------------------------------------------
        This change only effects ws-dataselect and ws-timeseries

        Refreshing queries which are near realtime (i.e. cover time ranges
        close to the present time)
        will more reliably result in newer and more current data sets
        being returned.
        Previous versions held data cached for an hour or more.

        -------------------------------------
        Internal logging changes
        -------------------------------------
        We now better track returned http status codes to better help
        identify system problems

        regards,
        IRIS DMC web services team
