SDDPT Viking Orbiter Archival Imaging Data on CD-WO


Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Time span: 1976-06-22 to 1980-07-30


This data set consists of processed versions of the Viking Orbiter archival imaging data. These include archive mosaics and stereo pairs, as well as other archive products. The majority of the data files are comprised of fixed length records, typically 6020 or 6336 bytes per block. The disk does contain some tapes which had variable length records - for more detail on the exact file structure, consult the COPY_LOG file accompanying each tape. Each CD-ROM has been formatted so that a variety of computer systems (e.g. IBM PC, Macintosh, Sun, VAX) may access the data. Specifically, the discs are formatted according to the ISO 9660 level 1 Interchange Standard, and file attributes are specified by Extended Attribute Records. These data were copied from magnetic tapes to CD-WO as part of the Science Digital Data Preservation Task.

This data set was created at JPL as part of its Science Digital Data Preservation Task (SDDPT), and a copy was provided to NSSDC for safekeeping. Numerous SDDPT data sets are not readily usable, as they represent bit copies of old data tapes and do not contain user documentation. Persons interested in ordering these data should contact the NSSDC person listed for this data set.

This is SPDSS ID 75-075A-0073, volumes VO_2001 - VO_2004
