A volume table is a chart to aid in the estimation of standing timber volume. These tables are based on volume equations and use correlations between certain aspects of a tree to estimate the volume to a degree of certainty. The diameter at breast height (DBH) and the merchantable height are used to determine the total volume. Difficulties ...
A number of different units were used in Brazil to measure length. One pé (foot) was equal to 0.33 m (with local variations). Some of other units are given below: [1] [5] 1 polegada (inch) = 1 ⁄ 12 pé [5] 1 palmo (palm) = 2 ⁄ 3 pé 1 vara (yard) = 3 + 1 ⁄ 3 pés 1 passo geométrico (pace) = 5 pés
The cord is a unit of measure of dry volume used in Canada and the United States to measure firewood and pulpwood. A cord is the amount of wood that, when "ranked and well stowed" (arranged so pieces are aligned, parallel, touching and compact), occupies a volume of 128 cubic feet (3.62 m 3). [43]
In contrast the volume of the Sag Branch Tuliptree (Liriodendron tulipifera), height 167.7 feet, dbh 7.08 feet, crown spread 101 feet) had a trunk volume of 2430 ft 3 (68.6 m 3) and a branch volume of 1560 ft 3 (44.17 m 3). [15] The volume of the branches on the tuliptree was only 64.2% that of the trunk. [15]
Alternatively, the crown area can be measured and crown spread calculated from that value. EasyAcreage [8] is a Google Earth area measurement tool that calculates the area of any shape outlined on the Google Earth display. The perimeter of the tree can be traced on a satellite photo, and the software will calculate the area.
Tree height is the vertical distance between the base of the tree and the highest sprig at the top of the tree. The base of the tree is measured for both height and girth as being the elevation at which the pith of the tree intersects the ground surface beneath, or "where the acorn sprouted."
In this case a better option would be to measure the standard girth measurement at 4.5 feet above ground level on the high side of the tree and note this in the measurement description [13] [17] The height of this measurement point above the standard base point at midslope should also be noted. If measuring a mountaintop forest of stunted trees ...
More specifically, geometrical size (or spatial size) can refer to three geometrical measures: length, area, or volume. Length can be generalized to other linear dimensions (width, height, diameter, perimeter). Size can also be measured in terms of mass, especially when assuming a density range.
