Basic principle

The so-called trigonometric principle of measuring tree heights is based on the measurement of distances and angles.

info.png Note:
If one uses a measurement device which does not enable to directly measure horizontal distances (or e.g. rely on fixed distances to the tree determined by optical principles) the measured distance has to be corrected. To avoid corrections in sloped terrain a practical solution is to move parallel to the slope and to find a position from which one can directly measure the horizontal distance.
