Abstract

System of direct measurement of heights of trees in foot.consists in the use of mobile abaces, pendulos that rotate on a parallel axis to the axis of turns of the abaces and mark in these the height of the tree, with a single reading and without having make a subsequent correction due to the slope of the ground. The abaces are groups of curves in intervals of 5 meters on a plane, indicating each of them an height h and being able to rotate the bacches by entering the angle bab2 so that for each height h will be a curve in the abacus. For each distance of station there is a different abacus. The parametric equations of the abacus are xfa cos bab2 - b sen (bab1 b bab2) eyfa sen bab2 bb cos (bab1 b bab2), where a is the distance between axis of turns of the abaces and pendulos and b is the length of the same, determining the height of the tree by hfd expression (tg bab1 b tg bab2) fd cos bab (tg bab1 b tg bab2).
