机载激光数据已经用于测量树高和推断林分郁闭度,Maclean、Krabill和Nelson(1986,1987)等的研究表明,沿激光断面不连续载线的激光高度测量值可与森林生物量或林木材积的地面测量值相关。研究还包括应用有限的地面抽样结合机载激光测量值估测某大林区面积上的林木材积和生物量。
Airborne laser data has been used to measure tree height and to infer canopy density. Studies by Maclean, Krabill and Nelson (1986, 1987) have shown that laser height measurements along discontinuous lanes of laser cross sections can be correlated with forest biomass Or the ground measurement of the timber volume. The study also included the application of limited ground sampling in combination with airborne laser measurements to estimate forest volume and biomass in a large forest area.
