描述了一种通过在随机点上进行测量的组合来估算森林中箔纸的技术:(1)在三脚架下方的垂直线上的叶片接触计数,(2)(2)在最低叶子上的高度上的瞄准镜(2)点,以及(3)叶子不遮挡的天空比例。
A technique is described for estimating a foilage profile in a forest by a combination of measurements over random lines of points: (1) counts of leaf contacts on a plumb line below a tripod, (2) sightings on the heights of lowest leaves over grids of points, and (3) the proportions of sky unobscured by leaves.
