Evaluation of a novel mobile device app for value-maximized bucking by chainsaw

Cross-cutting of felled trees into logs (“bucking”) is a critical step in converting standing timber end products, as it predetermines and limits number, type value products that can be produced from the logs. Bucking by chainsaw currently not aided information technology volume recovery depend on operator’s proficiency. A recently presented novel mobile device-based application (“T4E App”) for assisting value-maximized bucking was evaluated during harvesting mature beech stand regarding taper curve estimation accuracy. Further, its patterns were benchmarked against an experienced choice time consumption app operation determined. Taper curves inadequately approximated log mid diameters (1.0 cm, SD=2.4) (0.02 m3 under bark [UB] m3, SD=0.04) significantly overestimated. Consequently, total observed (–8.7%) (–8.1%) smaller than estimated. Inappropriate pricing insufficient top caused further reductions. Thus, recovered (59.61 UB; –8.8%) (€2,099.66; –8.6%) Chainsaw totals differed marginally (58.59 €2,117.99). About 85% variation working with explained tree number grade sections. After accounting consumption, net 5.1% lower case. The T4E App nevertheless represents first towards digitalization motor-manual may soon enhanced more accurate derived terrestrial laser scanning data.
