Restore capability to write output miniSEED to stdout by specifying the output file as a single dash, e.g. "-o -"

Added by Chad Trabant about 2 years ago

FetchData 2015.014 includes support for the IRIS Federator system (using the irisws-fedcatalog service interface).

A new command line option of -F instructs FetchData to perform client-side federation, collecting data from multiple FDSN data centers with data matching the request criteria.

FetchEvent 2014.340 released, fix parsing error for depth

Added by Chad Trabant over 2 years ago

A parsing error for event depth values was fixed.

The error was due to the conversion of values from meters to kilometers before the complete value had been parsed, partial values can be returned by the XML parser. This error appears to only occur relatively rarley and for only when parsing very large XML documents, i.e. large requests.

FetchMetadata version 2014.316 released

Added by Chad Trabant over 2 years ago

FetchMeta now includes a new option -mts or -matchtimeseries that includes matchtimeseries=TRUE in the request to the fdsnws-station web service. As documented in the FDSN web service specification, this option limits the results to metadata for which the criteria match the availability of time series data.

Added by Chad Trabant over 2 years ago

FetchData version 2014.253 was released with many changes since the previous release (2014.107).

Highlights include:

* Use POST capabilty of fdsnws-station service, which is much faster to transport and parse over the XML (support is required for 1.1 services).

* Many optimizations for large requests by re-organizing internal metadata handling and removing an unnecessary encoding check during download.

* Translate empty location strings in metadata to "--" identifiers for data requests.

* Add detection of stream truncation identifier, exit and print an error if present.
