A mirror dendrometer and the determination of the form class by means of a dendrometer

Heikkilä T. (1932). A mirror dendrometer and the determination of the form class by means of a dendrometer. Acta Forestalia Fennica vol. 38 no. 3 article id 7269. https://doi.org/10.14214/aff.7269

Abstract

A mirror dendrometer consists of a hollow metal tube and three mirrors that are installed in the tube in a certain way. The tool is used to determine the diameter of a tree trunk above the reach. The article presents the formulas that can be used to correct the measuring mistakes that are caused by the wrong position of the dendrometer.

To determine the form class of a stand with the diameter measurements from a certain height the Jonson’s diameter relations tables can be used. The calculation of the form class for a stand is presented.

The PDF contains a summary in Finnish.
