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.
