CYLINDRICAL PROJECTION MAP OF JANUS

Janus2.gif is a shaded relief map of Janus, the 'larger coorbital'
satellite of Saturn.  It is the same map as Janus.gif, but has been
reprojected to the Simple Cylindrical projection.  As with all maps, it
is the cartographer's interpretation and not all features are necessarily
certain given the limited data available - this interpretation stretches
the data as far as is feasible.  The original map was published in its 
full form with latitude-longitude grid, in:

Stooke, P.J. and Lumsdon, M.P., 1993.  "The Topography of Janus", 
    EARTH, MOON AND PLANETS, V. 62, pp. 223-237.

Positions in the map are controlled by a digital shape model, described
in that paper.  For that 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).  That relief drawing was scanned and reprojected to this
cylindrical projection.  Longitude 180, which faces away from Saturn,
runs down the centre of the map.

This version of the file, with labels intact, is in the public domain.
