        INFORMATION ABOUT THE VIKING LANDER IMAGE BROWSER

     In this directory are a series of HTML files that provide a
simple method for browsing through the Viking Lander image
archive.  The system is designed to be viewable by many WWW
browsers.  Your browser must be able to handle HTML tables in
order to view the pages properly.  To start the image browser,
open the INDEX.HTM file from this directory in your WWW browser.
If you need detailed instructions on using this image browser,
there is additional help available in the HELP.HTM file.  There
is a separate image browser for images from each Viking Lander.
The browser on this CD-ROM only displays images found on this
volume.

     A browse image exists for each PDS archive image.  The
browse image size is a factor of four smaller in both lines and
samples than the archive image.  Browse images are contrast
enhanced for better viewing of features and are stored in GIF
format.  Browse images are organized into subdirectories using
the same structure as the archive products (see the AAREADME.TXT
file).

     There are five different types of pages in this image
browser.  The top page (file INDEX.HTM) is the starting point.
It has general information about the browser structure.  It also
links to the data dictionary page, help page, and image directory
pages.  The data dictionary page contains keyword definitions for
parameters in the PDS image label.  The help page explains the
components of the browser and ways to navigate through the
browser.  Each browse image directory has an image directory page
that links to the individual browse images.  Finally, each image
has a page that displays the image, some navigation buttons, and
keywords and values from the PDS label.
