Lunar Consortium Data Historical Archive
Assorted Lunar Images and Data from 1965 to 1992
Presented here are safed versions of variety of data selected from a collection of data commonly referred to as the Lunar Consortium Data. This pre-Clementine data set consists of products derived from Apollo, Lunar Orbiter, Galileo, and Zond 8 missions. Select data collected from Earth-based observations are also included as part of this collection.
Introduction
This zip file contains a variety of data selected from a collection of data commonly referred to as the Lunar Consortium. Compilation of this Lunar Consortium Data was initially directed by Dr. Philip Davis (now retired).
An included Hypertext Markup Language (HTML) file is intended as a user interface to information and data provided in the archive. Using a web browser,, open the 'index.htm' file located in the 'root' directory. This HTML document will direct you to browse versions of each image data product in the zip file.
Data Formats
All document files, detached label 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-based systems because the CR/LF sequence is identically used on these systems. On UNIX-based systems, the expected end-of-record mark is simply a LF character. However, UNIX text editors can read and access the text 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. In addition to the standard ASCII text file format used for documentation files, some documentation files may additionally exist in other forms to facilitate easy access to these files. File names with extension "DOC" are formatted as Microsoft Word Version 6.0 documents. File names with extension "PDF" are formatted as Adobe Portable Document Format (PDF) 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 (v3) 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 Clementine Base Map image archive uses the form:
^object = n
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.
