Note:This is the same field in Example 1 using OptiSurface4D instead if the field is planted without furrows.

Proposed Cut/Fill Map
An OptiSurface4D design has been calculated instead of OptiSurface1D. This shows how close OptiSurface Designer can follow the lay of the land resulting in significantly reduced earthworks. This resulted in a smooth design with earthworks of 92 m3/ha (35 yd3/ac).
