OPTIMUM SURFACE LANDFORMING<br />
• Design software to calculate optimized 3D field topography<br />
that improves irrigation & surface drainage<br />
• Uses 3D GPS machine control for earthmoving<br />
• Advantages over traditional laser grading:<br />
– Much Lower Earthworks (Aim: 70% Lower)<br />
– Much Lower Topsoil Movement<br />
• See OptiSurface.com for more details<br />
