High tree is one dimension that is used in the measurement timber.<\/span> Tree height is defined as the distance or length of the shortest line between a point on the tree by its projection on a flat surface (more details can be seen in Figure 24).<\/span>

From the picture, it is instructive:<\/span>
\n 1) The total height is the shortest distance from point to point treetop projection on a flat plane.<\/span>
\n 2) High-tree bole (Tbc) is the shortest distance from point to point bole projection on a flat plane.<\/span><\/p>\n

Things to remember!<\/strong><\/span>
\n The term applies only tree height for trees that are still standing, while for tree felling of trees used long term.<\/span> Furthermore, the question may arise in your mind is how to measure the height of a tree?<\/span> To answer these questions, let you see the following description!<\/span><\/p>\n

The formula is based on the angle-degree<\/strong><\/span>
\n The formula is based on a formula high goniometry ie tangent formula.<\/span> Height measurement is illustrated in the form of an isosceles triangle with a corner in the second leg of 45o.<\/span> Keidentikkan associated with range-degree angle (\u03c6 = \u03b4) against the angle-percent (\u03c6 = \u03b4), so that the amount of 45 ^{o<\/sup> identified with 100% (Figure 25).<\/span>

Furthermore, the formula developed by considering the position \/ position of the eyes when aiming tree or trees opposite position when shot.<\/span> There are three positions on the eye when shooting a tree, namely:<\/span>
\n 1) The position of the eye located between the base and the top rod (rod tip \/ canopy, bole or certain high) and shoot direction parallel to the flat \/ flat crosshairs direction (Figure 26).<\/span>
\n<\/a>
\n Figure 26. The basic formula of high based on the position (1)<\/span><\/p>\n

From the images could be obtained high trees formula, namely:<\/span>
\n T = (t1 + t2)<\/span>
\n T = (Sn x tangent \u03b1) + (Sn x tangent \u03b2)<\/span>
\n T = Sn x (tangent to tangent \u03b1 + \u03b2)<\/span><\/p>\n

Information :<\/span>
\n T = total tree height (m)<\/span>
\n t1 = BC tree height (m)<\/span>
\n t2 = AB tree height (m)<\/span>
\n Sn = distance between the viewfinder flat with trees (m)<\/span>
\n \u03b1 = angle formed when shooting treetops (m)<\/span>
\n \u03b2 = angle formed when aiming the base of the tree (m)<\/span><\/p>\n

2) The position of the eyes is still located between the base and the top of the stem, but the direction is not parallel to the plane shutter panel \/ viewfinder upward direction (Figure 27).<\/span>
\n<\/a>
\n Figure 27. The basic formula of high based on the position (2)<\/span><\/p>\n

From the images could be obtained high trees formula, namely:<\/span>
\n T = (t1 + t2)<\/span>
\n T = (Sn x tangent \u03b1) + (Sn x tangent \u03b2)<\/span>
\n T = Sn x (tangent to tangent \u03b1 + \u03b2)<\/span><\/p>\n

Information :<\/span>
\n T = total tree height (m)<\/span>
\n t1 = BC tree height (m)<\/span>
\n t2 = AB tree height (m)<\/span>
\n Sn = distance between the viewfinder flat with trees (m)<\/span>
\n \u03b1 = angle formed when shooting treetops (m)<\/span>
\n \u03b2 = angle formed when aiming the base of the tree (m)<\/span><\/p>\n

3) The position of the eyes is lower than the base of the stem \/ shoot upward direction (Figure 28).<\/span>
\n<\/a>

From the images could be obtained high trees formula, namely:<\/span>
\n T = (t1 – t2)<\/span>
\n T = (Sn x tangent \u03b1) – (Sn x tangent \u03b2)<\/span>
\n T = Sn x (\u03b1 tangent – tangent \u03b2)<\/span><\/p>\n
