Custom Formula Entry

The TreeDetect system allows users to enter custom timber volume formulas.
This is useful when you want to apply specific, proprietary, or research-based formulas for stand calculations.

Available Fields​

  • Formula name: a freely chosen name that can be used to retrieve the saved formula later.
  • Saved formulas: previously saved formulas can also be selected.
  • Formula: the mathematical expression to be used for calculation.

Available Variables​

  • D: trunk diameter (cm)
  • H: tree height (m)
  • p1, p2, … pN: arbitrary constants

✅ Advantage: The custom formula feature allows TreeDetect to support personalised forestry calculations, giving the user full control over the calculation model. Custom formulas can be saved and reused in future surveys with a single click.

Example​

v = (p1 + p2*D*H + p3*D + p4*H) * (H/(H-1.3)) * k * D^2 * H / 10^8
