metadata.revistascielo.dc.description: This work evaluate different models for estimating volume and height along the stem, in order to guarantee more precise inputs in the optimization systems for obtaining multi-products. It was tested the taper equations proposed by Demaerschalk, Ormerod, Schoepfer and Hradelzky. These models were tested for the commercial diameter of 7 and 28 cm in Eucalyptus sp. trees. The database was obtained from upper stem diameter measurements of 16 years-old trees, in a total of 32 sample trees for the model fitting and 27 sample trees for the validation test. Based on the graphic residual analysis, on the statistics (correlation coefficient, relative standard error, bias (B), average of the differences (MD) and standard deviation of the differences (DPD) and on the test of Leite & Oliveira (2002), it was verified that the Ormerod model presented better volume estimates and the Schoepfer model provided better height results.
