GLOBAL PHOTOMOSAIC OF EPIMETHEUS

Epmethe2.gif is a photomosaic of the surface of Epimetheus, the 
smaller co-orbital satellite of Saturn.  A shaded relief drawing of
Epimetheus is available as EPIMETHE.GIF.  A map of Epimetheus was 
published in:

Stooke, P.J., 1993.  "The Topography of Epimetheus", EARTH, MOON AND
    PLANETS, V. 63, pp. 67-83.

The mosaic is a composite of three Voyager images.  Some sections of the
satellite were in shadow or beyond the limb in the available images.
The horizontal dark band crossing the centre of the lower part of the
mosaic is the shadow of Saturn's F ring cast on the satellite.  Faint
narrow bands running diagonally across the centre of the lower part are
artifacts caused by dark columns of pixels in the source image.  
Positions in the photomosaic and map are controlled by a digital shape
model, described in that paper.  For this map, the three dimensional 
convex hull of the shape model was projected into the Morphographic 
Conformal Projection (the conventional Stereographic Projection modified
for non-spherical worlds).  As with all conformal (true shape) 
projections, the scale in these maps varies, increasing from the centre
to the outer edge.

The map projection is described in:

Stooke, P.J. and Keller, C.P., 1990.  "Map Projections for Non-Spherical
Worlds / the Variable-Radius Map Projections", CARTOGRAPHICA, V. 27, No.
2, pp. 82-100.
