Hi Folks; I've stalled on trying to figure this one out and need some help.
I have a large database containing elevation steps (polygons) in 1000' increments and want to change these to contours (lines). Simply converting the polygons to lines won't work because I then end up with overlapping contours of different elevations. (For example, a 2000' step would end up having both an inner and outer line, each with a value of 2000'. The outer line would identically overlap with a 1000' contour and the inner contour would be identical to and overlap with a 3000' contour.) How can I convert this polygon dataset to a line-based dataset without having these overlapping lines of different values? Please email your suggestions directly to me and I'll post a summary.
