Site calibration

Calibration is the process of adjusting projected (grid) coordinates to fit the local control. A calibration calculates parameters for transforming WGS‑84 coordinates into local grid coordinates (NEE).

You should calculate and apply a calibration before:

  • staking out points
  • computing offset or intersection points

If you calibrate a project and then survey in real time, the General Survey software gives real-time solutions in terms of the local coordinate system and control points.
