What additional processing was done to the contours after generation?

Contours with a value of zero were deleted, unless there were also contours with negative elevation values in the same area. This additional processing was done for cosmetic reasons as some of the NED data were not of sufficient quality in coastal areas to facilitate making a satisfactory zero-elevation contour.
