1.7 | Terminology & Definitions
Armed
Automatic control is enabled and ready to assume implement control when engagement conditions are met.
Benchmark
A known reference position or elevation used to align or verify machine position relative to the active project or terrain surface.
Blade Shift
A temporary adjustment applied to blade height or cross-slope relative to the active design surface without modifying the underlying project data.
Control Mode
The active automatic control strategy used to determine how the implement responds relative to the target surface or terrain.
Current Height
The measured elevation of the controlled point at the machine’s current position.
Design Height
The elevation defined by the active project surface or plane at the machine’s current position.
Engaged
Automatic implement control is actively controlling hydraulic output to achieve the target surface or control objective.
GNSS
Look Ahead
A predictive control function that anticipates upcoming terrain changes and adjusts implement response to improve surface accuracy and machine stability.
Marker
A user-defined reference point stored within a project for operational, surveying, or alignment purposes.
Original Height
The measured terrain elevation recorded before material movement or grading operations occur.
Plane
A mathematically defined flat grading surface generated using slope, elevation, and orientation parameters.
Position Quality
The estimated reliability of GNSS and sensor data used for terrain positioning and automatic control functions.
Project
The collection of surfaces, planes, linework, markers, terrain data, and operational settings associated with a worksite or job.
Surface
A terrain model or design representation used for guidance, visualisation, and automatic implement control.
Target Height
The elevation the system is attempting to achieve at the controlled point relative to the active surface or control mode.
Terrain Alignment
The process of aligning machine position and elevation relative to known terrain references, benchmarks, or project coordinates.
Zero
A positional or elevation offset applied to align the machine with known terrain or project reference data.
