That's a nice piece of kit, but it doesn't really do what I want;

Ideally the poly vertices would lie on the contour lines so I can apply the correct texture.
Here's a partial sketch of what I'd like to get to for the high-poly version;

(The low-poly version would only use the contours bordering different terrain types).
My current plan is to walk the contour lines, breaking them into line segments as I go, then use the segments to somehow generate triangles. A bit vague! Maybe I should just use the end-points of the line segments as vertices and use *gulp* Delaunay triangulation?
