Overview

Benchmark study demonstrates accurate stem curve and volume retrieval in managed boreal forests, highlighting mobile laser scanning efficacy across canopy layers.

Key Points

  • Accurate estimation of stem curve and diameter at breast height is achievable using mobile laser scanning, even under challenging and dense boreal canopy conditions.
  • A root-mean-square error below 10% was achieved for stem curve and diameter estimates, while novel bias compensation reduced diameter bias by 55–99% across laser scanners.
  • Assessment across six laser scanning systems demonstrates that low beam divergence supports robust stem volume estimation, outperforming airborne canopy coverage in dense plots.
