Description:
Abstract:
Callisto was observed through the Voyager 1 and 2
spacecraft in 1979 (Smith and others, 1979a, b). 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.

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.
