Ocena przydatności danych skanowania laserowego do inwentaryzacji drzew rosnących pojedynczo i w zadrzewieniach liniowych
Use of a laser scanning data to inventory of single trees and trees groving in tree-lines

Summary/Abstract: Because of many functions, of trees in agricultural land, they are protected. Preservation of woodlots is one of requirements of «Good Agricultural Practises» . is also condition for receiving subsidies to farmers for agricultural production. To take of them, it is necessary to monitor woodlots condition. This paper deals with the use of laser scanning data to trees inventory. Data acquired by LiDAR are good material for the measurement of trees, because they do not have distortions, which are typical by aerial images. The paper contains the results of measurements of trees with normalized Digital Surface Models obtained from laser scanning data acquired 2007 and 2015. Achieved results are compared with field measurement. The results, even thought are not accurate enough to measure trees crowns dimensions, may indicate changes in the field and be applied as a practical basis to carry out the Rapid Field Visit.
