Information

These CD-ROM's contain the archive of raw images from the Mars Global Surveyor camera (The Mars Orbital Camera, or MOC). There are two distinct sets of CD-ROMs in this collection. The first set contains images in decompressed format from the pre-mapping aerobraking orbits and the second set contains compressed images from the mapping orbit. The images are stored with PDS labels and have undergone packet decommutation, removal of the MOC communications protocol headers, and reformatting. No additional geometric or radiometric processing or calibration was done.

The first set starts at volume 1 and contains raw images as Decompressed Standard Data Products (DSDP's). These images are all from the initial aerobraking orbit phases which preceded the mapping orbits. The CD's also contain ancillary data files and browse images in JPEG format, HTML documents that support a web browser interface to the CD's, an index file that tabulates the contents of the CD, and documentation files.

The second set, from the MGS science mapping orbit, starts at volume 1001. These volumes contain compressed images. The CD also contains ancillary data files that support the MOC SDP archive. These files include an index file ('imgindx.tab') that tabulates the contents of the CD and gives useful ancillary information, and documentation files. Decompression software is included on the CD for Windows and Unix machines, there is no decompression software provided for Macintosh.
