Since no one else seems to be answering this, I'll mention what I have:

I have a line segment map of the world.  Points are in latitude and
longitude.  The complete world is 103496 line segments.  Each segment
has 3 decimal places of accuracy, and consists of 4 points (x1,y1)
(x2,y2) for an average of 31 characters per segment, or a total of
3,191,655 bytes -- too large to post or e-mail.  Just North America
is 400,000 bytes of 12534 segments.

I hope someday to convert this world map to a more compact form,
but that's not what I get paid for.
