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.
