SHADED RELIEF MAP OF PROTEUS, CYLINDRICAL PROJECTION

Proteus2.gif is a shaded relief map of Proteus, a small inner satellite
of Neptune.  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.
A small part of this map was published in:

Stooke, P.J., 1994.  "The Surfaces of Larissa and Proteus", EARTH, MOON
   AND PLANETS, V. 65, pp. 31-54.

Positions in the 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).  The map was compiled in that projection and reprojected to the
Simple Cylindrical projection.  Longitude 0 is at the center of the map
and faces Neptune.  As with all cylindrical projections, this map is
severely distorted near the poles (top and bottom edges).

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