This paper analyzes the potential of airborne laser scanner data for measuring individual
tree height growth in a boreal forest using 82 sample trees of Scots pine. Point clouds (10
points/m2, beam size 40 cm) illuminating 50 percent of the treetops were acquired in
September 1998 and May 2003 with the Toposys 83 kHz lidar system. The reference height
and height growth of pines were measured with a tacheometer in the field. Three different
types of features were extracted from the point clouds representing each tree; they were the …
