I did some work on random terrain once. You can see the results here:

If this is what you're looking for, I can try to explain it.

Cool. I made these: http://flywheel.be/wouter/maps/

Similar in concept, I guess. What technique are you using? I always start from fractal + voronoi but I think that's fundamentally flawed; going from raster to vector is silly when you could have gone straight to vector.

I'm starting with a triangle and expanding random sides with triangles or trapezoids, filling in tightly acute angles as well.
