The NSW
Natural Resources Commission (NRC) engaged the University of Newcastle to analyse
Airborne Laser Scanning (ALS) for monitoring forest conditions and biophysical
outcomes. The analysis looked at the relationships between topographic
position, fire severity and harvesting history, including harvest intensity.
The ALS
data used was LiDAR LAS data captured across 540,000 hectares of NSW state
forest. These included 27 state forests across 7 regions (Eden, Batemans Bay,
Bulahdelah, Wauchope, Coffs Harbour, Styx River and Casino) across 3 separate
capture years (2012, 2016 and 2023).
The LiDAR
metrics developed include canopy top height, canopy coverage, canopy foliage
density, and skew. The canopy top height and canopy cover LiDAR metrics displayed
in this webmap were calculated at a 30 metre x 30 metre resolution.
