- •
An indirect method to estimate the woody surface area proportion in forests was validated.
- •
A 3D modelling and simulation framework was implemented for highly detailed 3D models.
- •
Sensitivity to stem distribution, stem density and PAI values was quantified.
- •
The method agreed to within 0.05 α of reference values and was robust to canopy structure variations.
