PH5: Why Another Archival Data Format?



       The impetus to provide a new data format for archiving stems from the inherent limitations with respect to the use of SEG-Y as a data archiving format, limitations such as: requiring vetted meta-data prior to converting the data into SEG-Y files, un-editable meta-data within the file, and inflexible, static data gathers.

PH5 addresses these limitations of SEG-Y as it:

  • allows the user to archive all waveforms early in the archiving process, minimizing meta-data problems from inhibiting the start of the archiving process. 
  • allows for the editing of the meta-data in data sets already archived, saving the archiver time and effort, otherwise necessary for reprocessing and re-archiving a data set.

  • provides for customizable data requests, where the user may request data, defining a unique start time and duration, in multiple formats; current formats available include SEG-Y and PASSCAL SEG-Y.
