I could probably cook something up for you - I have all the relevant
code already (GPX reading, contouring, etc) ni Java/Processing. 
Processing just added PDF export, which you could then open in
Illustrator or whatever, or I could also do PostScript without too
much trouble.

Send over a sample file and I'll see what I can do.
