A comparative analysis of airborne laser scanning (ALS), terrestrial laser scanning (TLS), and field data collection methods in estimating tree attributes has been performed in the study. Tree height (H), diameter at breast height (DBH), crown base (CB) and crown diameter (CD) have been estimated using manual and automatic methods for spruce and beech. Strong correlation was observed among scanning H and field-measured H for spruce with error of the estimates (SEE) from 1.4 m to 2.2 m. DBH estimates from TLS manual method showed the correlation coefficient, r = 0.96 for spruce and beech with average SEE of 2.9 cm. Automatic TLS method for DBH of beech was poorer than for DBH of spruce. TLS estimates of CB were better both for manual and automatic methods than ALS estimates. CD estimates from ALS showed better agreement with field measurements (r = 0.71, SEE = 1.2 m) than did CD estimates from TLS (r = 0.52, SEE = 1.4 m).
