The photographic coverage of Callisto is incomplete, particularly coverage between longitudes 270° and 310°, and south of latitude 55° S. Additionally, only very poor resolution coverage (>20 km/pxl) was obtained south of 10° N., between longitudes 50° and 160°. Image resolution is as high as 2.3 km per line pair for some Voyager 1 images and as high as 3.9 km per line pair for some Voyager 2 images. In both sets of images, solar incidence angles range from 10° to 90°. The variable and mostly poor image resolution, sun angles higher than about 45°, and smearing by spacecraft motion make the image set difficult to analyze. In addition, bright frosts obscure topographic features in the north polar region (Spencer and Maloney, 1984). Whether bright frosts also occur in the south polar region is unknown. Purpose: Supplemental_Information: Conventional photogeologic techniques for mapping planets (Wilhelms, 1990) were employed for recognizing and mapping material units, structures, and stratigraphic relations. Photogeologic units were identified based on albedo, crater density, surface features, and cross-cutting relations. All craters larger than 60 km in diameter were mapped and classified according to their stage of degradation. Because the poor resolution makes crater counting difficult and correlation of counts between areas uncertain, qualitative estimates of crater frequency rather than quantitative counts were used to gain insight into relative unit ages. The surfaces seen thus far on Callisto seem to be remarkably simple for such a large satellite.
