Always use a clinometer to measure the gradient of a paths slope a clinometer is a hand held instrument used for measuring a gradient in degrees or percentage to measure the gradient of a paths slope requires both the observer (the person holding the clinometer) and target to be a constant height above the ground, so generally a height of. A simple version of surveying equipment, a clinometer can be used to find the angle you are looking, for instance from where you are standing to the top of a tree combined with the distance to the base of the tree (and a little bit of trigonometry), this can be used to calculate the height of the tree. Height measurements equipment needed you only need three pieces of equipment to properly measure a tree: a measuring tape, a calculator (with cosine and tangent functions), and an inclinometer to measure angles.
These are some of the questions that can be answered by using an instrument called a clinometer, which can measure both height and the gradient of an incline many jobs, from surveying to forestry, use clinometers to precisely make calculations. Instrument used for measuring a gradient in degrees or percentage to measure the gradient of a paths slope requires both the observer (the person holding the clinometer) and target to be a constant height above the ground, so generally a height of. Students with a solid geometry background could be asked to estimate the height of an object (ex: tree, flagpole), using the clinometer and a measuring tape (or electronic range finder if you are lucky enough to have access to one.
Height = (tangent of its angle from horizontal) x (its distance in plan) the suunto clinometer is used to measure a point’s degrees from horizontal and a surface’s slope in percent or slope angle. Measuring slope with a clinometer a forester using a clinometer makes use of basic trigonometry first the observer measures a straight-line distance d from some observation point o to the object then, using the clinometer, the observer measures the angle a between o and the top of the object. Read this to learn how to measure the height of a tall tower using a clinometer, a friend, and simple physics formulas slide 1 of 8 in my last article, we discussed three measuring techniques and the construction of a clinometer. Instruction for tangent measurement using a clinometer + tape + calculator a measure the angle to the top of the tree as seen with the clinometer = a b measure the baseline = the distance from the observer to the trunk c calculate with the calculator: a = tan angle a x d (a is the height from eye level to the measured top) d measure the.
Using page 4 and 5 of today’s flipchart_clinometer project day 1, i am going to introduce the concept of indirect measurement using the eiffel tower problem on page 5, i am going to try to draw out of students the idea that they would be able to accurately measure the distance they are standing away from the tower. Because you held the clinometer at eye level, you actually measured the height of the object starting at your eye's height above the ground use a tape measure to find out how tall you are from the ground to your eye level, add the result to the number you measured in the last step. Alternatively use a protractor (in fact the clinometer can be made using a protractor to replace the paper plate) now look through the straw so that the treetop is visible. View of data collector using clinometer to measure tree height figure 5 top of tree crown this example is a silver maple (acer saccharinum), a dendritic tree form in middle age figure 6 example of height measurement with the tree base below eye level base of tree reading is -85 ft and top of tree reading is 278 ft total height is 355 ft.
My students need 14 100-foot tape measures to measure distances on the ground which will be used to calculate the height of a tall tree or building for the past 2 years, my geometry class has measured objects indirectly by using a handmade clinometer and a meterstick for good results, the students. Is there an easy way to measure the height of a tree up vote 113 down vote favorite 38 foresters use a clinometer to determine the height of a tree since another answer mentioned the use of a phone, i looked to see if a clinometer app was available for my iphone there are several and one has a very strong 5 rating.

Tree height measurement jump to navigation jump to search this article outlines the basic in general, the clinometer is used to measure the angle θ from the eye to the top of the tree, and then the horizontal distance to the tree at eye level is measured using a tape. Calculate the height of the tree by using the proportion of your own shadow’s length measure how far they are from the base of the tree with a tape measure this is the height of the measure the distance between you and the tree 3 use a clinometer to measure the angle of elevation to the top of the tree 4 find the tangent of the. How tall is this tree using a clinometer to the distance away from the tree should be at least equal to the height of the tree 2) measure the distance to the tree and the height that the clinometer will be from the ground 3) look through the clinometer with one eye and at the tree with the other eye (this takes a bit of getting used. Using the clinometer to measure a vertical angle in degrees 17 if you must measure a vertical angle in degrees instead of a slope, you may use the model 4 clinometer (as described above.
• measure slope in percent using a suunto clinometer • measure height of trees and other objects using a suunto clinometer as needed in soil survey work. Students will use the clinometer and the trigonometric ratios to measure the height of various structures students will complete a poster describing the process of creating and using the clinometer to find the heights. Pick a spot to measure your object (i measured a telephone pole) you should be far enough away from your object that you can see the top of it, and you need to be on level ground with the base of the object. Intro: using a clinometer to measure height in this instructable, i'll show you how to use a clinometer to measure the height of a tall object (for help constructing your own clinometer from basic classroom materials, click here .
