SMITH" INSTITUTION_NAME = "UNIVERSITY OF ARIZONA" DATA_SET_DESCRIPTION = "NASA's Voyager Project and Planetary Data System (PDS) have created an archive of planetary digital images acquired by the twin Voyager spacecraft. Compact Disk Read-Only Memory (CD-ROM) is the archival medium used for distribution to interested scientific research organizations and libraries. Each CD-ROM volume contains approximately 2500 images stored in individual compressed files. In addition to the images, supplemental information exists on the CD-ROMs. 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 CD-ROMs 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. This CD-ROM was formatted according to the guidelines specified in the in the document 'Standards for the Preparation and Interchange of Data Sets', (1988), Version 1.0, T.Z. Martin, M.D. Martin, and M.J. Braun, JPL Document Number D-4683, Jet Propulsion Laboratory, Pasadena, Ca. 91109. This standard represents the initial form of the label and object structures within the PDS and does not represent the most current standards supported by the PDS. The most current version of the PDS standards are outlined in the 'Planetary Data Systems Standards Reference', (1992), JPL Document Number D-7669 " END_OBJECT OBJECT = INSTRUMENT_DESCRIPTION_GROUP INSTRUMENT_NAME = {NARROW_ANGLE_CAMERA, WIDE_ANGLE_CAMERA} INSTRUMENT_TYPE = VIDICON_CAMERA 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." END_OBJECT END
