 Abstract:
 The entire mapped area was covered by near-vertical
 photography from the second encounter, and the eastern
 part, from long 15 to about 110, was covered by oblique
 photography from the first encounter. No third-encounter
 images were acquired. The entire visible area may be viewed
 stereoscopically by combining images from the first and
 second encounters taken at different viewing angles or by
 combining second-encounter images of the same area taken at
 different viewing angles. These combinations provided
 excellent qualitative control of topographic relief and a
 good quantitative photogrammetric base. However,
 sun-elevation angles of the images are limited to less than
 25, and image resolutions are no higher than about 0.5 km
 per picture element. Therefore, the south polar geologic
 map reflects mostly large-scale processes and topographic
 information, whereas other mercurian quadrangle maps
 benefit from greater albedo
 discrimination and, in some cases, higher resolution.
 Purpose:
 Supplemental_Information:
 The imaged part of the Bach region covers about 1,570,000
 km 2 . Its surface consists of craters of a wide variety of
 sizes and morphologies, as well as plains units, scarps,
 and ridges. It includes three double-ring basins that range
 from 140 to 200 km in diameter: Bach (after which the
 region is named), Cervantes, and Bernini. Another large
 crater, Pushkin, is 240 km in diameter and occurs at the
 map boundary at lat 65 S., long 25. Both Bach and Bernini
 display extensive fields of secondary craters. An unusual
 area between lat 69 and 80 S. and long 30 and 60
 consists of young, relatively smooth plains marked by many
 flat-topped ridges unlike any seen in other areas of
 Mercury. Scarps similar to Discovery Rupes (in the
 Discovery quadrangle adjacent to the north) are relatively
 common throughout the Bach region. The most common terrain
 units in the region are the plains units, which display a
 wide range of small-crater densities.

 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.
