- NOTES ON USING THE IMAGE INDEX TABLE
-
-
- The image index table contains one row (record) for each image file on
- the Voyager Uranus CD-ROM disk set. The table contains a total of 6538
- rows, where rows 1 to 2838 identify the compressed images on volume
- VG_0001, rows 2839 to 5389 describe the images on volume VG_0002,
- and rows 5390 to 6538 describe the images on volume VG_0003.
-
- The image index table is formatted so that it may be read directly
- into many data management systems on various host computers. All
- fields (columns) are separated by commas, and character fields are
- enclosed in quotes. Each record consists of 512 bytes, with a
- carriage return/line feed sequence in bytes 511 and 512. This allows
- the table to be treated as a fixed length record file on hosts which
- support this file type and as a normal text file on other hosts.
-
- The structure and content of the image index table are described in
- file VOLINFO.TXT located in the DOCUMENT directory. A label coded in
- the Object Description Language (ODL), providing a formal description
- of the index table structure, is located in file IMGINDEX.LBL.
-
- Users of most commercial data management systems should be able to
- use the list below to define the names and characteristics of each
- field and then to load the table into their data manager using a
- delimited ASCII text input format. If necessary the specific column
- start positions and lengths can be used to load the data.
-
- For personal computer users a DBASE III DBF structure is also provided
- in the file IMGINDEX.DBF. This file can be used to load the
- IMGINDEX.TAB file into DBASE III with the following commands:
-
- USE IMGINDEX
- APPEND FROM IMGINDEX.TAB DELIMITED
-
- Once the table is loaded into DBASE III, it can generally be
- automatically loaded into other data managers or spreadsheets which
- provide search and retrieval capabilities.
-
- The list below presents each field in the image index table, along
- with a 10 character terse name for each field, the full PDS data
- dictionary name, the data type which would normally be used for
- loading the field into a data management system, the field width and
- the number of decimal places in numeric fields.
