Some methods of sampling triangle based probability polygons for forestry applications Errico, Darrell
Abstract
There is interest in forest sampling methods which have the ability to provide reliable estimates of volume without incurring unreasonable costs. Fraser (1977), to this end, described an individual tree variable probability sampling method which selects sample trees with probabilities based on the areas of polygons derived from triangles. A comparison of some alternative methods of sampling these polygons confirms Fraser's work and demonstrates that the method proposed by him probably has the greatest potential for practical forest sampling.
