Abstract: Modern forest harvesters and processors have the capacity to generate and record a lot of data using onboard sensors and computers. Outputs contain detailed data for stems, logs cut and time. When the Global Navigation Satellite System (GNSS) function is available geospatial coordinates and time stamps can also be included. Not only does it offer a navigation tool to aid the machine operator, it also generates opportunities for detailed production reports, machine productivity assessment and forest inventory reconciliation. A possible further application of such technology is the generation of forest productivity maps that can help us to predict, with a high level of detail, the characteristics of the forest across the terrain. Having a detailed forest productivity map could serve as a means of understanding variations across sites and exploring the possibility of site-specific management for future rotations, a concept also known as precision forestry. Future Forests Research supported this project as part of their harvesting research programme goal to realise gains in productivity and reduce the cost of harvesting by introducing improved harvesting technologies. Innovation is not only finding and developing new technologies, but also taking full advantage of what is already available.
