1. INTRODUCTION
This archive contains part of the Mars Orbiter Camera (MOC)
Reduced Data Record (RDR) archive.
This archive contains ancillary data files that support the MOC DSDP
archive. These files include browse images stored in a Joint
Photographic Experts Group (JPEG) format, an index file
('imgindx.tab') that tabulates the contents of the archive and gives useful
ancillary information, and documentation files. For more information
on the contents and organization of the archive volume set refer to the
"Archive Contents, Directory, and File naming conventions" section of this
document.
The MOC RDR archive was compiled for the National Aeronautics and
Space Administration (NASA) by the PDS Imaging Node, using data products
provided by Malin Space Science Systems.
The image files are organized according to NASA's Planetary Data
System (PDS) standards. An image file is organized as a PDS
labeled file containing an "image object".
2. DISK FORMAT
This disk has been formatted so that a variety of computer systems
(e.g. IBM/PC compatible, Macintosh, Sun) may access the data.
Specifically, it is formatted according to the ISO 9660 level 1
Interchange Standard. For further information, refer to the ISO 9660
Standard Document: Reference Number ISO 9660-1988, 15 April 1988. The
extended attribute records (XAR) supported by the ISO are not used in
this volume series.
3. FILE FORMATS
All document files and tables are stored as ASCII stream-record files.
In a stream-record file, records (lines of text) are separated by a
carriage-return <cr> and line-feed <lf> character sequence. The
<cr>/<lf> sequence marks the end-of-record and the start of a new
record. This organization works well for the Microsoft-DOS systems
because the <cr>/<lf> sequence is identically used on these systems.
On Macintosh systems, an end-of-record mark is simply a <cr>
character. Macintosh text editors can read and access these files,
but a special-character indicator (usually a "square box" character)
will mark the "extraneous" <lf> character at the beginning of each
line. On UNIX systems, an end-of-record mark is simply a <lf>
character. UNIX text editors can read and access these files, but a
special-character (usually a ^M sequence) indicator will mark the
"extraneous" <cr> character at the end of each line. File names with
extension "TAB", "LBL", "LAB", "TXT", and "CAT" are formatted as ASCII
stream-record files.
Tabular files are formatted so that they may be read directly into
many database management systems of various computers. All fields are
separated by commas, and character fields are enclosed in double
quotation marks ("). Character fields are left justified, and numeric
fields are right justified. The "start byte" and "bytes" values
listed in the labels that describe the tabular files do not include
the commas between fields or the quotation marks surrounding character
fields. The records are of fixed length, and the last two bytes of
each record contain the ASCII <cr>/<lf> characters. This scheme
allows a table to be treated as a fixed- length record file on
computers that support this file type and as a normal text file on
other computers.
PDS labels are object-oriented. The object to which the label refers
(IMAGE, TABLE, etc.) is denoted by a statement of the form:
^object = location
in which the carat character (^) indicates that the object starts at
the given location. In an embedded label, the MOC RDR archive uses
the form:
^object = n <BYTES>
where "n" points to the starting byte location of the object. (The
first byte in a file is designated as byte location 1.) For detached
labels (labels existing in their own file) the object location is
signified as:
^object = "file.nam"
In this form, the object of the label description exists in the file
named "file.nam". For a description of the PDS object label
specifications, consult JPL document D-7669.
4. ARCHIVE CONTENTS, DIRECTORY, AND FILENAMING CONVENTION
The files on this archive are organized starting at the root or 'parent'
directory. Below the parent directory is a directory tree containing
data, documentation, and index files. In the table below directory
names are indicated by brackets (<...>), upper-case letters indicate an
actual directory or file name, and lower-case letters indicate the
general form of a set of directory or file names.
