Laser Scanning Measurements on Trees for Logging Harvesting Operations
Logging harvesters represent a set of high-performance modern forestry machinery, which can finish a series of continuous operations such as felling, delimbing, peeling, bucking and so forth with human intervention. It is found by experiment that during the process of the alignment of the harvesting head to capture the trunk, the operator needs a lot of observation, judgment and repeated operat...
متن کاملModelling environmental limits to light use efficiency for a canopy of two broad-leaved tree species with contrasting leaf habit
We used outputs from a model of canopy carbon uptake [Dungan et al. (2004) Functional Ecology 18: 34–42] and measurements of irradiance (PAR, 400–700 nm) intercepted by the canopy to investigate the effect of daily changes in environmental conditions on daily light use efficiency, ε, for a canopy comprising two broadleaved New Zealand tree species with contrasting leaf habit. Irradiance absorbe...
متن کاملIndustrial harvesting of olive tree pruning residue for energy biomass.
In Mediterranean countries, olive tree pruning residue represents an abundant source of energy biomass, still largely unexploited for lack of cost-effective harvesting technology. The authors tested two industrial pruning harvesters, capable of overcoming the limits of lighter units appeared in the past years. One of the machines was designed for application to a powerful farm tractor, whereas ...
متن کاملOperational monitoring of forest logging activities: an application of Precision Forestry approach for monitoring cable cranes logging operations
An important aspect to Precision Forestry (PFOR) is implementing operational monitoring of forest chain logistics. PFOR can be considered as the application of information technology (IT) to the forest sector. Its introduction has the aim to improve the efficiency and the performances of the forest sector, including all the related monitoring activities to satisfy management tasks. So PFOR has ...
