Using airborne laser scanning data for detecting canopy gaps and their understory type in mature boreal forest

Table 1 Five different exclusive CG-classes based on the six field inventory classes

DDW is gaps with downed deadwood, VEGE is gaps with different vegetation, UNDER is gaps with DDW and VEGE, NO_UNDER is gaps with no DDW and VEGE and OTHERS is gaps with small amount of DDW or some seedlings found in field inventory. Man-made canopy gap is class 1, 2 is seedlings from 0.3 m to 1.3 m tall, 3 is seedlings over 1.3 m tall, 4 is depth of downed deadwood under 0.3 m, 5 is depth of downed deadwood over 0.3 m, and 6 is dense lesser vegetation. Insignificant amount of content is marked with a, and in great abundance of content is marked with b
