Voyager Project and Planetary Data System (PDS) have created
an archive of planetary digital images acquired by the twin Voyager
spacecraft (Voyager 1 and Voyager 2). This initial collection includes
all of the images acquired by Voyager 2 as it passed by the planet
Uranus, and selected near-encounter images of Jupiter, Saturn, and
their satellites taken by both spacecraft.
The current Voyager archive resides on eight CDROM volumes. Each volume
contains approximately 2500 images stored in individual files. The
Uranus volumes, (volumes one through three), store the entire image
collection acquired during Voyager 2's encounter with Uranus. The Saturn
volumes, (volumes four and five), and the Jupiter volumes, (volumes six
through eight), contain the best nearest-encounter images for the
respective planets and their moons.
In addition to the images, supplemental information exists on the
CDROMs. This includes documentation providing a user with information
about the organization and contents of the disk. Software source code
is included to provide programmers with tools to process the image files.
There are browse images, sub-sampled versions of the full-resolution
images, which allow users to rapidly view the archive collection with
their interactive display. Finally, there are image index files
containing information about all the images stored in the archive.
The set of images on the CDROMs are raw; no processing has been
performed other than organizing the original telemetry into
raster-formatted files and compressing the image data using a Huffman
encoding algorithm. To make full scientific use of the image
collection, it is necessary to understand the radiometric and geometric
properties of the camera system and perform corrections to the data."

INSTRUMENT_DESCRIPTION = "
There are two cameras onboard each Voyager spacecraft, one with a wide
field of view and the other with a narrow field of view. Both cameras
return data in a digital raster-format containing 800 scan lines and 800
samples per scan line. Each picture element (pixel) in the two
dimensional image array is represented as an 8-bit value, and the
value--in the range 0 to 255--is proportional to the amount of light
detected at that point. The cameras are equipped with color filters so
images taken through complementary filters can be combined during ground
processing to produce color images."
