There are places in SEED into which everything, albeit awkwardly in some cases, has to fit. This creates a format that everybody may grouse about equally, but lives within. As a result, there has been a remarkable level of data sharing across networks. We were one of the early part... [more]

Hello all, In our effort to be as inclusive as possible the next generation miniSEED proposals were sent to a long list of recipients including two FDSN Working Groups. Unfortunately many of the replies to these messages are only going to the FDSN Working Group lists. If you are not already a member of one of these mailing lists you can follow the ongoing discussions in the FDSN Message Center here: http://www.fdsn.org/message-center/topic/fdsn-wg3-products/ http://www.fdsn.org/message-c...

Hi all, Apologies for the flurry of emails about change proposals, but ideally we now will have somewhat organized feedback on each of them. I did not include the following two proposals: #4 was to fix a typo in the straw man, which will be fixed. #10 was to accommodate non-integer sample rates in the header. The 2016-3-30 straw man already accommodates this by denoting the sampling rate as an IEEE float. Please let me know if anything is unclear or if I have missed any proposals. We ... [more]

Hello everyone, You are receiving this email because either you were in the initial list I sent the announcement to, are a member of FDSN WGII or WGIII or have expressed an interest in attending these discussions at the EGU. This includes a good mix of FDSN Network and data center personnel as well as representatives from equipment manufacturers. I am attaching a draft agenda that identifies the topics of discussion as well as giving the time and meeting place. I am also attaching a straw ma... [more]

Dear Colleagues and Members of Working Group II: I have been observing some of the discussions and exchanges in WGII concerning the efforts of developing a standard for a new/updated miniSEED format. It is clear from these discussions, as well as from input from users, data managers, and equipment manufacturers, that the time is right for FDSN to address -- with a new standard -- the shortcomings of the current miniSEED format. The development, adoption, and promotion of standards thr... [more]
