| Aug 10, 2011 at 15:44 | comment | added | Patrick | I've accepted whuber's answer, as it gives me exactly what I was looking for, but I think there may be other answers for the general case. Several I had found include using XTools or ET Geowizards to convert the polylines to polygons, or else removing the holes from the non-overlapping polygons. | |

| Aug 10, 2011 at 14:06 | comment | added | Patrick | Yes, that's correct. In many forums it seems as though many people have had the opposite problem of trying to convert overlapping polygons to cocentric, non-overlapping ones. (including this particularly thorough one from our own whuber: link) | |

| Aug 10, 2011 at 11:24 | comment | added | artwork21 | what do you mean by a set of contour lines, is this one contour layer or more than one? A single contour layer lines should not cross/overlap. | |
