 Description:
 Abstract:
 Ganymede, the largest of the Jovian satellites discovered
 by Galileo, is a Mercury-sized object having a diameter of
 5,268 km. Ganymede's Jupiter-facing side is always the
 same. The low density of 1.93 . 10 3 kg m -3 suggests that
 Ganymede has a large component of water ice; its component
 of rock is unknown (Smith and others, 1979a). Absorption
 bands at 1.55 and 2.0 mm are evidence for water-ice
 abundance at its surface (Pilcher and others, 1972).
 Ganymede's two major terrain types are dark and light
 materials, each covering about
 50 percent of the surface. Also, many of the impact craters
 dispersed across the map region have bright ejecta or
 bright rays; some have dark rays.
 Purpose:
 Supplemental_Information:
 Overall coverage of the map region is poor (see resolution
 diagram). Only about a quarter, which is located in the
 sub-Jovian hemisphere (long 270° to 0° to 90°) imaged by
 Voyager 1, is covered by images of less than 2.0 km/pixel
 resolution. The area between long 120° and 240° is covered
 by Voyager 2 images with poor resolution due to
 foreshortening. Part of Galileo Regio, the largest expanse
 of dark material on Ganymede, is in this area. The map
 region and surrounding areas are covered by a light-colored
 polar cap extending down to a mean latitude of about 48° N.
  (Squyres, 1980a). The cap is visible
 on far-encounter images only and does not affect the
 contrast on the images used for geologic mapping.

 Attribute_Accuracy:
 Attribute_Accuracy_Report:
 All attributes created during the creation process were
 verified by displaying the lines in both the database and
 the spatial coverage, but no formal tests were performed.
 Logical_Consistency_Report:
 These data are believed to be logically consistent, though
 no tests were performed. Line geometry is topologically clean.
