P. Kovácsová, M. Antalová: PRECISION FORESTRY – DEFINITION AND TECHNOLOGIES Šumarski list br. 11–12, CXXXIV (2010), 603-611 Modern information technologies allow quick and direct communication among single forest operations. This allows reducing costs and increasing yield for forest enterprise and wood processing industry. There are some disadvantages and problems with tools of precision forestry. One of them is that tools of precision forestry are not standard in all forest enterprises. Individual tools of precision forestry must be necessary combined in order to obtain more precise information, not only quantitative but also the qualitative aspects of the forest resource. The most common combination of tools are GIS, GPS and remote sensing technologies, which offer adequate resources of gaining precision data and additional accuracy of information used for decision. The other tools have narrow range of utilization and they are focused on specific field of forestry management. The next disadvantage is the price of some required data types which are significantly influenced by cost of tools operations and their accessibility. Tools of precision forestry are demanding mainly on hardware and some of them also software. Because of high demands on hardware, the acquisition costs are increased and tools are not reachable to all forest enterprise at the present. All recorded data from tools is processed by suitable software and additionally necessary information is gained. Information has been recognized as being of similar importance as the basic production factors in producing enterprises. It plays an important role in planning, implementation and controlling production processes while supporting the management by providing relevant data on how to dispose of all relevant production factors (Kätsch 2006). There are some issues of information quality, mainly problems with poor accuracy, low precision, incompleteness and missing relevancy, all of which can be removed by combination and further development of tools of precision forestry. Obtained information from treated data can be used by all forest operations, wood processing industry and environmental protection professionals. Information for forest operations is used by selecting the suitable stand, harvesting operation, forwarding, storage and transport wood. Knowledge of information significantly influences planning, organization, control and duration of forestry works. For wood processing industry there is important information about wood as dimension, grade, grain, blight disease, stiffness and taper. This information influences production wood products thereby profitability wood industry. For environmental protection there is important information mainly about soil as erodibility, disturbance, Figure 6 Diagram of Precision forestry. Slika 6. Dijagram “preciznog šumarstva”.
