Table 3 Dominant height difference statistics (1999–2002) by damage class as estimated by photointerpretation (source: NFI) (the damage levels, associated to the damage classes, are given in parenthesis)
From: Stand-level wind damage can be assessed using diachronic photogrammetric canopy height models

2 | (10–50%) | − 13.1 | − 0.2 | 2.1 | 6.2 | 12.6 | 37.9 |
