             abstract = "The objective was to perform the modeling of trunk sections 
                         through the cloud of points. The data were obtained in clonal 
                         plantations of Eucalyptus spp., with multiple terrestrial laser 
                         scanning in circular plots (400m2). The plantation has 2, 4 and 5 
                         years and spacing 3.6 x 2.2 m. The registration of the point 
                         clouds was performed to allow the analysis of multiple scans in a 
                         single coordinate system. Subsequently, the trees were isolated in 
                         a semi-automatic way by Label Connected Components algorithm. The 
                         total height was obtained from the difference of the maximum and 
                         minimum elevation (Zmin and Zmax) for each tree. The filtering of 
                         trees previously isolated was performed using the FDmax algorithm, 
                         which allowed the application of trunk modeling using an irregular 
                         triangular network (TIN). The trunks were divided into 2 meters 
                         sections for the three-dimensional modeling and a posteriori were 
                         compared with the field data obtained by the conventional method. 
                         The volume obtained by modeling of de three different trees were 
                         compared with data obtained by Smalian method, the determination 
                         of the volume in the 2 years tree and 5 years tree until third and 
                         fifth log respectively presented differences smaller than 15% and 
                         below to the volume estimate by Smalian method that tend to 
                         overestimate de volume. And the 4 years tree only the first log 
                         presented volume below and with difference of 15% compared to 
                         Smalian. The main problem was in tree crown, which the branch 
                         interfere in process to obtain points of the trunk.",
