What is a Clinometer?

A tool for measuring angles to determine heights of objects without directly measuring them.

An instrument that measures the steepness of slope.

It is used by:

Highway construction engineers to measure angles of the land,

Movie production engineers to

measure the height of the sun, And by forestry engineers to

measure the height of trees.

Things to Remember at the Site

The person holding the clinometer should be at point “X.” Person 2 will go about 50 m out away from “Person X.” A third person is needed to read the clinometer. Slope is labeled on the Hydrology Site Map (p. 38)

You Can Measure A Tree Height

Look at the top of a tree through your straw.Move back (still looking at the tree top) until

your clinometer (the washer) is on 45 degrees.

Then measure your height (only your eyes to the ground).

And the distance from your feet to the tree base.

Lastly, add the measurements together: this is the height of the tree.
