Abstract

Currently, the use of measuring methods and laser scanning tools is one of the most relevant and priority areas for solving the problems of monitoring and evaluation of forest plantations. Such measurement can be carried out independently or in combination with aerial video shooting, and can also be carried out by ground studies on test areas. According to a number of indicators, laser scanning surpasses others known today, such as aerial photography, earth sounding, etc., remote methods for assessing the qualitative and quantitative characteristics of the forest fund. The use of aerial and ground laser scanning in combination will allow achieving high accuracy in determining the main forest taxation parameters. It is advisable to use the formed methodological principles and techniques when developing specific methods for determining indicators as separate factors determining the appropriate types of forest availability. Since logging of machine complexes requires more detailed research, namely, it is necessary to have data on the distribution of trees in the stand, their availability, more accurate dimensional and quality indicators taking into account the location of trees, this article discusses a method for measuring the size and quality indicators of a stand based on the use of unmanned aerial vehicles (UAVs) in conjunction with ground-based laser scanners. They allow to measure with high accuracy the main forest taxational characteristics: the species (species) composition of the forest fund, the diameters of the tree trunk at any height, the height of trees, the main defects of wood, the cross-sectional area, the sortable total and sortable stock of wood.
