Abstract
Investigation of Benefit of Applying Handheld Scanner to Measure Tree Height and Diameter at Breast Height
Highlights
Many countries have recently established a national forest survey and monitoring system to analyze the exact amount of forest resources and identify changes in forest ecosystems.[1,2,3] In Korea, a national forest resource survey is conducted to obtain basic data on forest statistics and assess the health of forest ecosystems.[4,5,6,7] The most basic part of a forest survey consists of several measurement tasks in the forest.[8,9,10] In forestry, measurement generally involves measuring, for example, the size and range of a tree using an instrument
Since the study site is an experimental forest, accurate diameter at breast height (DBH) measurements can be made using calipers. These results indicate that DBH can be measured using a handheld scanner
The tree heights were within 10 cm of the reference values
Summary
Many countries have recently established a national forest survey and monitoring system to analyze the exact amount of forest resources and identify changes in forest ecosystems.[1,2,3] In Korea, a national forest resource survey is conducted to obtain basic data on forest statistics and assess the health of forest ecosystems.[4,5,6,7] The most basic part of a forest survey consists of several measurement tasks in the forest.[8,9,10] In forestry, measurement generally involves measuring, for example, the size and range of a tree using an instrument. The geometric information obtained from a 3D laser scanner is actively used in reverse engineering and quality inspection in various industries, and it is expected to be used as a new technology for tree management among the mobile technology trends in the field of forestry.[23] In this study, we obtained data on forests by measuring DBH and tree height using a handheld scanner.
