| description | The two most common ways of measuring the breast height diameter of a tree stem is to use a caliper or a diameter measuring tape. In Sweden there is a tradition of using a caliper when estimating the volume of a forest. From an international perspective the diameter measuring tape is the more common tool.
The purpose of the study is to show which of the two methods that differ the least from the correct area. Furthermore, the study compares the results from usage of different types of cross calipering methods to each other. It also compares the differences in results these methods presents when measuring pine and spruce.
The study started by analyzing and calculate the correct area from 40 tree trundles of pine and spruce. By comparing the result from the cross caliper measuring and the diameter tape measuring it is showed that the caliper is more precise than the diameter tape. The study also indicates that measurements of spruce in thinning forests differ the most from the correct area. |
