Forestry and environment
Canopy, ground and change: forests measured tree by tree, and the ground beneath them.
Canopy height, structure and stand inventory across the estate, from LiDAR and multispectral imagery captured together. Each repeat survey is aligned to the last, so growth, harvest, fire and dieback are measured between captures.
- On stable open ground, checked independently of the alignment, the 2011 survey agrees with the 2024 survey to a median −6 mm (NMAD 64 mm, 95th percentile 157 mm; 94.4 % within 15 cm): relative agreement between surveys, not absolute accuracy. Hobart 3D city model
