If the finished "thing" (I avoid the word object) is to be 2-D, try the
SATELLITE projection in MAP_SET.

If you want a 3-D "thing", you could do a CYLINDRICAL EQUIDISTANT plot
with MAP_SET. CONTOUR will return the coordinates of the isopleths
(PATH_INFO, PATH_XY). Then transform the longitude-latitude coordinates
into 3-D space and use direct or object graphics to display the resulting
lines.
