These data, supplied by the Orbiter Imaging Team, are 4- x 5-in. B/W mosaics. Hand-rendered mosaics are available for much of the coverage obtained by the Viking Orbiter cameras. For the most part, these mosaics provide contiguous coverage of scenes made up from individual images and no attempt has been made to conform to a global control net. Measurements made from these mosaics will be highly inaccurate. Mosaics produced by the US Geological Survey (USGS) designated as MC quads or MC subquads and built upon the appropriate shaded relief map are valid mapping coverage. Each mosaic, identified by the prefix 211- and a four-digit number, is supplied with a footprint plot providing the individual picno as well as roll and file order numbers for the individual frames making up the mosaic. All of these numbers should be specified when ordering individual frames. In a few cases where the particular version of a frame in the mosaic is not available, a similar version of that frame is designated on the footprint plot. The mosaic summary and index (75-083A-01I) should be used to select these data.
