The objective of this work was to analyze the accuracy of piling factor estimates using digital photography and software especially developed for this purpose. Six trucks carrying five piles each, owned by ACESITA ENERGÉTICA Ltd., were used in this research. The analysis revealed that the average difference between the factors determined by the photographic method and the actual factors was approximately 3.2%, with a tendency for over estimation of the values obtained by the photographic method. The "t" test analysis suggested that the differences observed between these factors were mainly due to the the poor piling up of the wood.
