The three-dimensional DigSmart machine automation control system from Leica Geosystems features a TrenchTool mode that can be operator-selected at the onboard computer. This Leica SmartTool will guide the operator as to exactly where to both trench and backfill. A second mode is SlopeTool, which ensures the operator does not over-excavate no matter how complex the specified profile is. A third mode, RampTool establishes height-position planes keyed to GNSS elevation data. The DigSmart 3D is compatible with all Leica 1200 survey instruments. Another Leica machine automation control product, GradeSmart 3D allows most production functions of a dozer or grader to be carried out by commands from the onboard computer.
