Hi Nicolas, thanks for your help. I don't think I am getting the same results as you. In answer to an earlier question of yours, I have attached a small (328K) zipped subset of a contour file with a representative set of the type of shapes found in the full size one, but when I apply the sequence of code in your post above, I get very little useful output. But I might doing something wrong. G.
