Network-Day Tape

Latest revision as of 18:53, 30 May 2019

The Network-Day Tape format, sometimes referred to along with the name of its creator, the Global Digital Seismograph Network, as the GDSN Network-Day Tape format or simply as the GDSN format, is a format for storing seismic station data in use primarily in the United States from somewhere around 1980^[1] to 1987, when the SEED format largely supplanted it, in the United States as well as internationally^[2]. As the name would suggest, it was meant for storing data on magnetic tape. It may have been designed by a "Madeline Zirbes" at the United States Geological Survey.^[3]
