The SMOOTHING of TIN CONTOURS

These views present three stages of a TIN process. The left one shows in red lines the breaklines measured for a highway project. No mass points are visible because none were included in the survey. The resulting TIN is shown in black lines. The raw contours derived from that TIN are in the central view. On the right the contours have been smoothed following the general lines of the method we have called eclectic in the previous pages. No matter how tightly packed they might be, the smoothed contours never intersect each other nor they cut the edges on the wrong side of the TIN vertices
